Speed Up Your Internet

1. First, open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ServiceProvider
2. Note the following lines (all hex dwords):
Class = 008 ( biggrin.gif - indicates that TCP/IP is a name service provider, don't change
LocalPriority = 1f3 (499) - local names cache
HostsPriority = 1f4 (500) - the HOSTS file
DnsPriority = 7d0 (2000) - DNS
NetbtPriority = 7d1 (2001) - NetBT name-resolution, including WINS
3. What we're aiming to do is increase the priority of the last 4 settings, while keeping their order. The valid range is from -32768 to +32767 and lower numbers mean higher priority compared to other services. What we're aiming at is lower numbers without going to extremes, something like what's shown below should work well:
4. Change the "Priority" lines to:
LocalPriority = 005 (5) - local names cache
HostsPriority = 006 (6) - the HOSTS file
DnsPriority = 007 (7) - DNS
NetbtPriority = 008 ( biggrin.gif - NetBT name-resolution, including WINS
5. Reboot for changes to take effect

2. Windows 9x/ME

1. The tweak is essentialy the same as in Windows 2000/XP, just the location in the Registry is slightly different. For a more detailed description see the Windows 2000/XP section above
2. Open the Windows Registry using Regedit, and (after backing up) navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider
3. You should see the following settings:
Class=hex:08,00,00,00

LocalPriority=hex:f3,01,00,00
HostsPriority=hex:f4,01,00,00
DnsPriority=hex:d0,07,00,00
NetbtPriority=hex:d1,07,00,00
4. The "priority" lines should be changed to:
LocalPriority=hex:05,00,00,00
HostsPriority=hex:06,00,00,00
DnsPriority=hex:07,00,00,00
NetbtPriority=hex:08,00,00,00
5. Reboot for changes to take effect

3. System.ini IRQ Tweak - Windows 9x/ME ONLY

1. Find your Network Card's IRQ

1. In order to add the entry to your System.ini file, you'd first have to find your NIC's IRQ
2. Right-click on My Computer icon on your Desktop, then left-click on Properties (a shortcut for that would be to press the 'Windows' + 'Pause' keys). Navigate to Device Manager and double-click on Computer. Under "View Resources" you will find a list of IRQs, each with description of the device that's using it. Note the IRQ number used by your Network Adapter

2. Adding the entry to System.ini

1. Once you've found the IRQ of your Network Card, you need to reserve some RAM for its use, by adding an entry to the System.ini file. You can edit the file in any text editor, however the easiest way is to use Windows' built in "System Configuration Editor"
2. Navigate to Start > Run and type sysedit . Find the [386enh] Section in the System.ini file and add Irq[n]=4096 under it, where [n] is the IRQ number of your NIC and 4096 is the amount of RAM you want to reserve in Kbytes. We recommend using 4096, however you can experiment with different values if you want. Save changes in the file, exit and reboot for changes to take effect.
Note: If you choose to try different values, keep in mind that reserving too much RAM for your NIC will decrease the amount of RAM available for applications, while reserving too little might not give the desired effect

3. Additional Thoughts
1. The only negative effect of the System.ini IRQ tweak is that it will reduce the amount of RAM available for running applications a bit, by reserving some specifically for your Network Card's use. The gain in performance usually outweighs the negative effect by far, considering any Computer with 32Mb of RAM or more
2. This tweak may or may not work for you. It is not a documented tweak by Windows
3. Keep in mind that if you add hardware to your system the IRQ of the Network Adapter might change, in which case you will need to modify the setting in System.ini
4. In systems with multiple NICs, you might want to add the setting for both IRQs. Also, you could reserve RAM for other IRQs if you wish, just use common sense and don't forget it reduces the amount of RAM available for running applications
5. If you are using an USB device, it does not have a specific IRQ, however you can try adding the entry using the IRQ of the USB Controller
6. For internal Cable Modems, you'd have to add the entry using the IRQ of your modem, rather than the IRQ of a Network Card



RESULTS WILL VARY
No matter how good your systems may be, they're only as effective as what you put into them.

Delete An Undeletable File

Open a Command Prompt window and leave it open.
Close all open programs.
Click Start, Run and enter TASKMGR.EXE
Go to the Processes tab and End Process on Explorer.exe.
Leave Task Manager open.
Go back to the Command Prompt window and change to the directory the AVI (or other undeletable file) is located in.
At the command prompt type DEL <filename> where <filename> is the file you wish to delete.
Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
Close Task Manager.

Or you can try this

Open Notepad.exe

Click File>Save As..>

locate the folder where ur undeletable file is

Choose 'All files' from the file type box

click once on the file u wanna delete so its name appears in the 'filename' box

put a " at the start and end of the filename
(the filename should have the extension of the undeletable file so it will overwrite it)

click save,

It should ask u to overwrite the existing file, choose yes and u can delete it as normal


Here's a manual way of doing it. I'll take this off once you put into your first post zain.

1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:\*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~1
6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

Create An FTP Server On Your Pc With Serv-U




Requirements:
Serv-U
No-IP.com Website

Quote:
Step 1. Getting a static IP address.
Get a static address for your FTP server. You will want to do this as opposed to using your IP address for several reasons. First, it’s easier keeping up-to-date. Imagine having to change all of your setting every time your IP changed. With No-IP, the No-IP service runs in background on your computer and updates your current IP address with your FTP server’s URL (for example, you get ftp://rkchoolie.serveftp.com). Second reason, you don’t want your IP address posted out there for everyone to see.

1. Go to www.No-IP.com to create a new user account.
2. Fill in the information that is required and the click Register button.
3. Your account has now been created and your account password has been emailed to you.
4. Check your email mailbox and wait for the mail that contains your password
5. Go back to www.No-IP.com and type your email address and password to login to your account.
6. Once in your account, click on Add a host in the left menu
7. Type in the Hostname you want (example: rkchoolie) and pick a Domain from the list (example: ftpserve.com)
8. Check Allow Wildcards and click the Submit button
9. You now have your static address (example: rkchoolie.serveftp.com)
10. Click on your OS link in the Dyn-Update Client in the bottom right menu and follow links to download the client
11. Once downloaded, install the software and type in your email address and password when asked.
12. Finally tick the checkbox near your static address.

You now have a static web address .


Quote:
Step 2. Installing and setting the FTP server
1. Install Serv-U 4.0.
2. Start Serv-U and use the wizard to setup your ftp.
3. Click next until you're asked for an IP address, leave it blank and then click next.
4. Type the domain name you've just registered above (example: preacher.serveftp.com) in the domain name field and then click Next.
5. You are asked if you want to allow anonymous access, select No and then click next.
6. You are then asked to create a named account, check yes and then click next.
7. Type in the user name you wish for this account (example: Harrie) and click next.
8. Type a password for this account (example: $p3c1aL). For security reasons, try to create a password with some letters, numbers and special characters. Then click next.
9. You will then be asked for the Home directory of the account you just created. Select the directory and then click next.
10. Select yes to lock this account to the Home directory. You want to do this so that the user can not go any further up that his home directory. Click next.
11. The account is now set so click finish.

Quote:
Step 3. Configuring user accounts
1. In the left tree-menu, select the account you've just created and then click on the General tab.
2. Check Hide ‘Hidden’ Files.
3. Check Allow only and enter the number one in the box.
4. Set the Max. download speed to what ever you want. If this is an account that many will be using, set it low to save on your bandwidth. I usually have mine set between 10 – 20. If you leave it blank, users will be able to download from you at full bandwidth.
5. Set the Max no. of users to how many you want to be able to log on at one time. This depends on your connection speed but try these (56 - 1, ISDN - 3, ADSL or cable - 5-6 users.)
6. Now, click on the Dir Access tab.
7. You should see the home folder in there. Highlight it and make your permissions.
8. If you only want users to be able to download check only Read, List, & Inherit.
9. If you want users to be able to upload, but to only one particular folder but not download, click the add button and then select that folder. Now highlight the folder and set these permissions on that folder. Check Write, Append, List, Create, & Inherit. Once you have made the permissions click on the up arrow that is located at the bottom right-hand corner. You want this special upload folder to be list first, before the home folder.
10. If there is a folder that you don’t want anyone to have access to, but it is inside the home folder, then click the add button and then select that folder. Now highlight the folder and make sure that all checkboxes are left. Once you have made the permissions click on the up arrow that is located at the bottom right-hand corner. You want this no access folder to be listed at the very top.
11. There are many other different sets of permissions you can play with. I just covered your basics.
12. Your server is now set!
13. Try logging on with the username and password and see if it works.

Converting to NTFS

Convert your File system to NTFS


Your hard drive must be formatted with a file system such as FAT, FAT32 or NTFS so that Windows can be installed on to it. This system determines how files are named, organised and stored on the drive. If you’re not using it already, NTFS (New Technology File System) is recommended for Windows XP because of the additional functionality it offers. If your PC came with Windows XP pre-installed then there’s a chance that you’re already using NTFS. If you’ve upgraded from Windows 98 or Windows Me you may still be using FAT or FAT 32. The option to change over to NTFS would have been available during the upgrade process. Don’t worry if you skipped this as it’s possible to convert at any time from within Windows XP without losing any data.

The recommended option
There are a number of features in Windows XP that will only work if the NTFS file system is present, which is why it’s suggested you make use of it. File and folder permissions, encryption and privacy options are just some of those you’ll be able to access. In particular, those of you who have set up user accounts will find NTFS invaluable. For instance, if you continue to use FAT or FAT32 anyone with physical access to the drive will be able to access the files and folders that are stored there. However, with NTFS you’ll be able to use a level of encryption (Professional Edition only) that will enable you to protect your data.

You’ll also find NTFS more reliable in that it’s more able to recover from disk errors than its FAT or FAT32 counterparts. A log of all disk activity is kept so should a crash occur, Windows XP can use this information to repair the file system when your PC boots up again. To find out what file system you’re using, open My Computer, right-click your main hard drive and choose Properties. Take a look at the General tab to see confirmation of the file system that’s in use.

Convert now
You can use the convert tool in Windows XP to change the file system on your hard disk from FAT or FAT32 to NTFS. The whole process is safe and your existing data won’t be destroyed. To begin, click Start -> Run, type cmd and press [Return]. At the command prompt type convert c: /fs:ntfs and press [Return] (where ‘c’ is the letter of the drive you’re converting). When you try and run the convert utility, it’s likely that Windows XP will be using your paging file so the process won’t be completed immediately. Therefore, you’ll see a brief message on screen informing you that the conversion will take place instead the next time Windows starts up. Having restarted, the Check Disk utility will run, the conversion will be performed automatically and you may find that your PC will reboot twice more.

The benefits
With your drive now running NTFS, it’s time to take advantage of the new options that are available. Having created a number of different user accounts you can now control the level of access that’s granted to individual users. For example, there are going to be certain files and folders that you’ll want some users to be able to access but not others. If you have Windows XP Professional Edition you can do this immediately.

Right-click any file or folder, choose Properties and select the Security tab. A dialog will be displayed showing the names of all your users. Alongside will be two columns which enable you to select levels of access for each of them, the permissions include Full Control, Modify, Read and Write. You can then check the appropriate box to determine whether or not to Allow or Deny a particular permission. For Windows XP Home Edition users, the Security tab won’t be immediately available. To access this option you’ll need to restart your PC, pressing [F8] until a menu appears. Next select Safe Mode and wait for Windows XP to start up. You can then set your options in the same way.

Another feature is NTFS compression. It’s quick and seamless as your file or folder is decompressed automatically when you access it. (Don’t confuse this with a Zip compression utility where the files need to be extracted before they can be accessed.) Although you may have used NTFS compression on a file or folder, there’s no way of telling just by looking at it. To remedy this, open My Computer, click Tools -> Folder Options and select the View tab. Under Advanced settings, scroll down and check the option ‘Show encrypted or compressed NTFS files in color’, then click Apply and OK. Take a look at your compressed items in My Computer and you’ll see the text label has changed from black to blue. Something else that’s exclusive to Professional Edition users is the Encrypting File System (EFS). You can use this to protect your important data so that no one else can read it. Your encrypted files and folders will only be accessible when you have logged into your user account successfully.

Convert to Basic and Dynamic Disks in Windows XP

Windows XP Professional supports two types of disk storage: basic and dynamic. Basic disk storage uses partition-oriented disks. A basic disk contains basic volumes (primary partitions, extended partitions, and logical drives).

Dynamic disk storage uses volume-oriented disks, and includes features that basic disks do not, such as the ability to create volumes that span multiple disks (spanned and striped volumes).

General Notes
Before you change a basic disk to a dynamic disk, note these items:


You must have at least 1 megabyte (MB) of free space on any master boot record (MBR) disk that you want to convert. This space is automatically reserved when the partition or volume is created in Microsoft Windows 2000 or Windows XP Professional. However, it may not be available on partitions or volumes that are created in other operating systems.

When you convert to a dynamic disk, the existing partitions or logical drives on the basic disk are converted to simple volumes on the dynamic disk.

After you convert to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk, and then convert the dynamic disk back to a basic disk. If you want to keep your data, you must first back up or move the data to another volume.

After you convert to a dynamic disk, local access to the dynamic disk is limited to Windows XP Professional and Windows 2000.

If your disk contains multiple installations of Windows XP Professional or Windows 2000, do not convert to a dynamic disk. The conversion operation removes partition entries for all partitions on the disk with the exception of the system and boot volumes for the current operating system.

Dynamic disks are not supported on portable computers or Microsoft Windows XP Home Edition.

Before you change a dynamic disk back to a basic disk, note that all existing volumes must be deleted from the disk before you can convert it back to a basic disk. If you want to keep your data, back up the data, or move your data to another volume.

How to Convert a Basic Disk to a Dynamic Disk

To convert a basic disk to a dynamic disk:

1) Log on as Administrator or as a member of the Administrators group.

2) Click Start, and then click Control Panel.

3) Click Performance and Maintenance, click Administrative Tools, and then double-click Computer Management.

4) In the left pane, click Disk Management.

5) In the lower-right pane, right-click the basic disk that you want to convert, and then click Convert to Dynamic Disk.

NOTE:You must right-click the gray area that contains the disk title on the left side of the Details pane. For example, right-click Disk 0.

6) Select the check box that is next to the disk that you want to convert (if it is not already selected), and then clickOK.

7) Click Details if you want to view the list of volumes in the disk.

8) Click Convert.

9) Click Yes when you are prompted to convert, and then click OK.

How to Convert a Dynamic Disk to a Basic Disk

To change a dynamic disk back to a basic disk:

1) Back up all the data on all the volumes on the disk you want to convert to a basic disk.

2) Log on as Administrator or as a member of the Administrators group.

3) Click Start, and then click Control Panel.

4) Click Performance and Maintenance, click Administrative Tools, and then double-click Computer Management.

5) In the left pane, click Disk Management.

6) Right-click a volume on the dynamic disk that you want to change to a basic disk, and then click Delete Volume.

7) Click Yes when you are prompted to delete the volume.

8) Repeat steps 4 and 5 for each volume on the dynamic disk.

9) After you have deleted all the volumes on the dynamic disk, right-click the dynamic disk that you want to change to a basic disk, and then click Convert to Basic Disk.

NOTE:You must right-click the gray area that contains the disk title on the left side of the Details pane. For example, right-click Disk 1.

Learn how to Crack Windows



Debug is a program that comes with modern versions of DOS (I do not know when I started shipping out with DOS). Anyway, all Windows users should have it already.

It's a great tool for debuging programs, unassembling and cracking, and reading "hidden" memory areas like the boot sector, and much more.

The following was copied from an assembly tutorial who's author we cannot credit, because we have no idea who he is.

Get into DOS and type "debug", you will get a prompt like this:
-

now type "?", you should get the following response:
assemble A [address]
compare C range address
dump D [range]
enter E address [list]
fill F range list
go G [=address] [addresses]
hex H value1 value2
input I port
load L [address] [drive] [firstsector] [number]
move M range address
name N [pathname] [arglist]
output O port byte
proceed P [=address] [number]
quit Q
register R [register]
search S range list
trace T [=address] [value]
unassemble U [range]
write W [address] [drive] [firstsector] [number]
allocate expanded memory XA [#pages]
deallocate expanded memory XD [handle]
map expanded memory pages XM [Lpage] [Ppage] [handle]
display expanded memory status XS

Lets go through each of these commands:
Assemble:

-a
107A:0100

At this point you can start assembling some programs, just like using a assembler. However the debug assembler is very limited as you will probably notice. Lets try to enter a simple program:

-a
107A:0100 MOV AH,02
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-g
A

Program terminated normally

That's the same program we did at the end of the previous chapter. Notice how you run the program you just entered with "g", and also notice how the set-up part is not there? That's because debug is just too limited to support that.
Another thing you can do with assemble is specify the address at which you want to start, by default this is 0100 since that's where all .COM files start.
Compare:

Compare takes 2 block of memory and displays them side by side, byte for byte. Lets do an example. Quite out of debug if you haven't already using "q". Now type "debug c:\command.com"

-c 0100 l 8 0200
10A3:0100 7A 06 10A3:0200

This command compared offset 0100 with 0200 for a length of 8 bytes. Debug responded with the location that was DIFFERENT. If 2 locations were the same, debug would just omit them, if all are the same debug would simply return to the prompt without any response.
Dump:

Dump will dump a specified memory segment. To test it, code that assembly program again:

C:\>debug
-a
107A:0100 MOV AH,02
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-d 0100 l 8
107A:0100 B4 02 B2 41 CD 21 CD 20
...A.!.

The "B4 02 B2 41 CD 21 CD 20" is the program you just made in machine language.

B4 02 = MOV AH,02
B2 41 = MOV DL,41
CD 21 = INT 21
CD 20 = INT 20

The "...A.!." part is your program in ASCII. The "." represent non-printable characters. Notice the A in there.
Enter:

This is one of the hard commands. With it you can enter/change certain memory areas. Lets change our program so that it prints a B instead of an A.
-e 0103 <-- edit program at segment 0103
107A:0103 41.42 <-- change 41 to 42
-g
B

Program terminated normally
-
Wasn't that amazing?
Fill:

This command is fairly useless, but who knows....
It fills the specified amount of memory with the specified data. Lets for example clear out all memory from segment 0100 to 0108, which happens to be our program.
-f 0100 l 8 0 <-- file offset 0100 for a length of 8 bytes with 0
-d 0100 l 8 <-- verify that it worked
107A:0100 00 00 00 00 00 00 00 00 .......
Yep, it worked.
Go:

So far we used go (g) to start the program we just created. But Go can be used for much more. For example, lets say we want to execute a program at 107B:0100:
-r CS <-- set the CS register to point to 107B
CS 107A
:107B
-g =100

You can also set breakpoints.
-a <-- enter our original program so we have something
107A:0100 MOV AH,02 to work with
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-g 102 <-- set up a break point at 107A:0102

At this point the program will stop, display all registers and the current instruction.
Hex:

This can be very useful. It subtracts and adds two hexadecimal values:
-h 2 1
0003 0001 <-- 2h + 1+ = 3h and 2h - 1h = 1h

This is very useful for calculating a programs length, as you will see later.
Input:

This is one of the more advanced commands, and I decided not to talk about it too much for now. It will read a byte of data from any of your computers I/O ports (keyboard, mouse, printer, etc).

-i 3FD
60
-

Your data may be different.
In case you want to know, 3FD is Com port 1, also known as First Asynchronous Adapter.
Load:

This command has 2 formats. It can be used to load the filename specified with the name command (n), or it can load a specific sector.

-n c:\command.com
-l

This will load command.com into debug. When a valid program is loaded all registers will be set up and ready to execute the program.
The other method is a bit more complicated, but potential also more usefull. The syntax is

L <address> <drive letter/> <sector> <amount to load>
-l 100 2 10 20

This will load starting at offset 0100 from drive C (0 = A, 1 = B, 2 = C, etc), sector 10h for 20h sectors. This can be useful for recovering files you deleted.
Move:

Move takes a byte from the starting address and moves it to the destination address. This is very good to temporary move data into a free area, than manipulate it without having to worry about affecting the original program. It is especially useful if used in conjunction with the r command to which I will get later. Lets try an example:
-a <-- enter our original program so we have something
107A:0100 MOV AH,02 to work with
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-m 107A:0100 L 8 107B:0100 <-- more 8 bytes starting from 107A:0100 into 107B:0100
-e 107B:0103 <-- edit 107B:0103
107B:0103 41.42 <-- and change it 42 (
-d 107A:0100 L 8 <-- make sure it worked
107A:0100 B4 02 B2 41 CD 21 CD 20 ...A.!.
-d 107B:0100 L 8
107A:0100 B4 02 B2 42 CD 21 CD 20 ...B.!.
-m 107B:0100 L 8 107A:0100 <-- restore the original program since we like the changes.
Name:

This will set debug up with a filename to use for I/O commands. You have to include the file extension, and you may use addition commands:

-n c:\command.com
Output:

Exactly what you think it is. Output sends stuff to an I/O port. If you have an external modem with those cool lights on it, you can test this out. Find out what port your modem is on and use the corresponding hex number below:

Com 1 = 3F8 - 3FF (3DF for mine)
Com 2 = 2F8 - 2FF
Com 3 = ??? - ??? (if someone knows, please let me know)

Now turn on the DTA (Data Terminal Ready) bit by sending 01h to it:
-o XXX 1 <-- XXX is the com port in hex

As soon as you hit enter, take a look at your modem, you should see a light light up. You can have even more fun with the output command. Say someone put one of those BIOS passwords on "your" computer. Usually you'd have to take out the battery to get rid of it, but not anymore:

MI/AWARD BIOS
-o 70 17
-o 71 17

QPHOENIX BIOS
-o 70 FF
-o 71 17

QGENERIC
-o 70 2E
-o 71 FF

These commands will clear the BIOS memory, thus disabling the password.
Proceed:

Proceeds in the execution of a program, usually used together withy Trace, which I will cover later. Like the go command, you can specify an address from which to start

using =address
-p 2

Debug will respond with the registers and the current command to be executed.
Quite:

This has got to be the most advanced feature of debug, it exits debug!

-q
Register:

This command can be used to display the current value of all registers, or to manually set them. This is very useful for writing files as you will see later on.

-r AX
AX: 011B
:5
-
Search:

Another very useful command. It is used to find the occurrence of a specific byte, or series of bytes in a segment. The data to search for can by either characters, or a hex value. Hex values are entered with a space or comma in between them, and characters are enclosed with quotes (single or double). You can also search for hex and characters with the same string:
-n c:\command.com <-- load command.com so we have some data to search in
-l
-s 0 l 0 "MS-DOS" <-- search entire memory block for "MS-DOS"
10A3:39E9 <-- found the string in 10A3:39E9

NOTE: the search is case sensitive!
Trace:

This is a truly great feature of debug. It will trace through a program one instruction at a time, displaying the instruction and registers after each. Like the go command you can specify where to start executing from, and for how long.
-a <-- yes, this thing again
107A:0100 MOV AH,02
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
-t =0100 8

If you leave out the amount of instructions that you want to trace, you can use the proceed (p) to continue the execution as long as you want.
Unassemble:

Unassembles a block of code. Great for debugging (and cracking)
-u 100 L 8 <-- unassembles 8 bytes starting at offset 100
107A:0100 MOV AH,02 <-- debut's response
107A:0102 MOV DL,41
107A:0104 INT 21
107A:0106 INT 20
Write:

This command works very similar to Load. It also has 2 ways it can operate: using name, and by specifying an exact location. Refer to back to Load for more information.

NOTE: The register CX must be set the file size in order to write!
NOTE: Write will not write .EXE or .HEX files.[SIZE=7][SIZE=14]

Create Shutdown and Reboot Shortcuts

First, create a shortcut on your desktop by right-clicking on the desktop, choosing New, and then choosing Shortcut. The Create Shortcut Wizard appears. In the box asking for the location of the shortcut, type shutdown. After you create the shortcut, double-clicking on it will shut down your PC.

But you can do much more with a shutdown shortcut than merely shut down your PC. You can add any combination of several switches to do extra duty, like this:

shutdown -r -t 01 -c "Rebooting your PC"
Double-clicking on that shortcut will reboot your PC after a one-second delay and display the message "Rebooting your PC." The shutdown command includes a variety of switches you can use to customize it. Table 1-3 lists all of them and describes their use.

I use this technique to create two shutdown shortcuts on my desktop—one for turning off my PC, and one for rebooting. Here are the ones I use:

shutdown -s -t 03 -c "Bye Bye m8!"
shutdown -r -t 03 -c "Ill be back m8 ;)!"

Switch
What it does

-s
Shuts down the PC.

-l
Logs off the current user.

-t nn
Indicates the duration of delay, in seconds, before performing the action.

-c "messagetext"
Displays a message in the System Shutdown window. A maximum of 127 characters can be used. The message must be enclosed in quotation marks.

-f
Forces any running applications to shut down.

-r
Reboots the PC.

Cracking BIOS Password using DOS Prompt

Here is the best way to crack the BIOS password in win 95/98:

Follow the steps below:

1) Boot up windows.
2) Go to dos-prompt or go to command prompt directly from the windows Start menu or Type COMMAND on RUN and hit Enter.
3) Type the command at the prompt: "debug"
4) Type the following lines now exactly as given..***

o    70    10        
o    71    20        
 quit                    

4) Exit from the dos prompt and restart the machine


Now the Password Protection gone For BIOS!!!!!!!!!!!!! 

***Note: I tested this in Award Bios........
There seems to be some issue regarding display drivers on some machines if this is used. Just reinstall the drivers, Everything will be fine...........
I  have not found any other trouble if the codes are used.
To be on safe side, just back up your data..........
The use of this code is entirely at ur risk.......... It worked fine for me..........

Computer Maintenance Tips

You may not realize it, but your computer and your car have something in common: they both need regular maintenance. No, you don't need to change your computer's oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware. Read on to learn what you can do to help improve your computer's security.

Getting started

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.
* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.
* Install software updates immediately.
When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.)
An ounce of prevention

A few simple steps will help you keep your files safe and clean.

* Step 1: Update your software
* Step 2: Backup your files
* Step 3: Use antivirus software and keep it updated
* Step 4: Change your passwords


Developing ongoing maintenance practices

Now that you've done some ground work, it's time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.

* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.


* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program's user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk
.
* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords
.

Making a schedule

One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular "appointment" with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.

Choosing A Good Domain Name

Another good tip for successful web experience...

Choosing a domain name for your site is one of the most important steps towards creating the perfect internet presence. If you run an on-line business, picking a name that will be marketable and achieve success in search engine placement is paramount. Many factors must be considered when choosing a good domain name. This article summarizes all the different things to consider before making that final registration step!


Short and Sweet

Domain names can be really long or really short (1 - 67 characters). In general, it is far better to choose a domain name that is short in length. The shorter your domain name, the easier it will be for people remember. Remembering a domain name is very important from a marketability perspective. As visitors reach your site and enjoy using it, they will likely tell people about it. And those people may tell others, etc. As with any business, word of mouth is the most powerful marketing tool to drive traffic to your site (and it's free too!). If your site is long and difficult to pronounce, people will not remember the name of the site and unless they bookmark the link, they may never return.


Consider Alternatives

Unless a visitor reaches your site through a bookmark or a link from another site, they have typed in your domain name. Most people on the internet are terrible typists and misspell words constantly. If your domain name is easy to misspell, you should think about alternate domain names to purchase. For example, if your site will be called "MikesTools.com", you should also consider buying "MikeTools.com" and "MikeTool.com". You should also secure the different top level domain names besides the one you will use for marketing purposes ("MikesTools.net", "MikesTools.org", etc.) You should also check to see if there are existing sites based on the misspelled version of the domain name you are considering. "MikesTools.com" may be available, but "MikesTool.com" may be home to a graphic pornography site. You would hate for a visitor to walk away thinking you were hosting something they did not expect.

Also consider domain names that may not include the name of your company, but rather what your company provides. For example, if the name of your company is Mike's Tools, you may want to consider domain names that target what you sell. For example: "buyhammers.com" or "hammer-and-nail.com". Even though these example alternative domain names do not include the name of your company, it provides an avenue for visitors from your target markets. Remember that you can own multiple domain names, all of which can point to a single domain. For example, you could register "buyhammers.com", "hammer-and-nail.com", and "mikestools.com" and have "buyhammers.com" and "hammer-and-nail.com" point to "mikestools.com".


Hyphens: Your Friend and Enemy

Domain name availability has become more and more scant over the years. Many single word domain names have been scooped up which it makes it more and more difficult to find a domain name that you like and is available. When selecting a domain name, you have the option of including hyphens as part of the name. Hyphens help because it allows you to clearly separate multiple words in a domain name, making it less likely that a person will accidentally misspell the name. For example, people are more likely to misspell "domainnamecenter.com" than they are "domain-name-center.com". Having words crunched together makes it hard on the eyes, increasing the likelihood of a misspelling. On the other hand, hyphens make your domain name longer. The longer the domain name, the easier it is for people to forget it altogether. Also, if someone recommends a site to someone else, they may forget to mention that each word in the domain name is separated by a hyphen. If do you choose to leverage hyphens, limit the number of words between the hyphens to three. Another advantage to using hyphens is that search engines are able to pick up each unique word in the domain name as key words, thus helping to make your site more visible in search engine results.


Dot What?

There are many top level domain names available today including .com, .net, .org, and .biz. In most cases, the more unusual the top level domain, the more available domain names are available. However, the .com top level domain is far and away the most commonly used domain on the internet, driven by the fact that it was the first domain extension put to use commercially and has received incredible media attention. If you cannot lay your hands on a .com domain name, look for a .net domain name, which is the second most commercially popular domain name extension.


Long Arm of the Law

Be very careful not to register domain names that include trademarked names. Although internet domain name law disputes are tricky and have few cases in existence, the risk of a legal battle is not a risk worth taking. Even if you believe your domain name is untouchable by a business that has trademarked a name, do not take the chance: the cost of litigation is extremely high and unless you have deep pockets you will not likely have the resources to defend yourself in a court of law. Even stay away from domain names in which part of the name is trademarked: the risks are the same.


Search Engines and Directories

All search engines and directories are different. Each has a unique process for being part of the results or directory listing and each has a different way of sorting and listing domain names. Search engines and directories are the most important on-line marketing channel, so consider how your domain name choice affects site placement before you register the domain. Most directories simply list links to home pages in alphabetical order. If possible, choose a domain name with a letter of the alphabet near the beginning ("a" or "b"). For example, "aardvark-pest-control.com" will come way above "joes-pest-control.com". However, check the directories before you choose a domain name. You may find that the directories you would like be in are already cluttered with domain names beginning with the letter "a". Search engines scan websites and sort results based on key words. Key words are words that a person visiting a search engine actually search on. Having key words as part of your domain name can help you get better results.

Recover Your Forgotten Windows Password

Because of the security features built into Windows XP, it is virtually impossible to get back into the system without the password.
You have several options to try and get around this problem.

If you have access to another user account with administrator rights, you can use that account to change the password
of the account that is locked out. You can also use the default Administrator account that is built into Windows XP.

First you need to boot the system into Safe Mode.
1.Restart your system.
2.When you see the blue Dell globe or screen, press the ( F8 ) key about 3 times a second.
3.You should get the Windows startup menu. Use the (Up or Down) arrow keys to highlight (SafeMode)
4.Press (Enter) on (Safe Mode), then press (Enter) on (Windows XP).
5.The system should boot to Safe Mode.

Once you are at the Account Log on Screen, click on the icon
for the user account with administrator rights, or click on the icon
for the administrators account.
Note: For Home the Administrator account isn't normally shown & in Safe Mode you have to press Ctrl+Alt+Delete keys twice to show.
For PRO you can do this in normal mode

When the system has booted to the desktop, use the following steps to change the accounts password.
1.Click Start, Control Panel, Administrative Tools.
2.Click Computer Management.
3.Double click Local Users and Groups, double click the folder Users.
4.Right click on the account name that is locked out, and click on Set Password.
5.You may get a warning message about changing the password, simply click proceed.
6.Leave the New Password box blank, also leave the Confirm Password box blank.
7.Click OK, and OK again.
8.Then close all Windows, reboot the system and try to log in.


There are also applications that can recover the password for you.
The following companies provide these applications at a cost.
iOpus® Password Recovery XP here.
LostPassword.com, here.
Asterisk Password Recovery XP v1.89 here.
Windows XP / 2000 / NT Key here.


If the above information does not help in recovering the password, the only option left is to
format the hard drive then reinstall Windows and the system software.

Change The Default Location For Installing Applications

As the size of hardrives increase, more people are using partitions to seperate and store groups of files.

XP uses the C:\Program Files directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/or directory by using a Registry hack.

Run the Registry Editor (regedit)and go to

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

Look for the value named ProgramFilesDir. by default, this value will be C:\Program Files. Edit the value to any valid drive or folder and Your Windows will use that new location as the default installation directory for new programs.

Change Your Start Button Name

Step 1 - Modify Explorer.exe File

In order to make the changes, the file explorer.exe located at C:\Windows needs to be edited. Since explorer.exe is a binary file it requires a special editor. For purposes of this article I have used Resource Hacker. Resource HackerTM is a freeware utility to view, modify, rename, add, delete and extract resources in 32bit Windows executables and resource files (*.res). It incorporates an internal resource script compiler and decompiler and works on Microsoft Windows 95/98/ME, Windows NT, Windows 2000 and Windows XP operating systems.


The first step is to make a backup copy of the file explorer.exe located at C:\Windows\explorer. Place it in a folder somewhere on your hard drive where it will be safe. Start Resource Hacker and open explorer.exe located at C:\Windows\explorer.exe.

The category we are going to be using is "String Table". Expand it by clicking the plus sign then navigate down to and expand string 37 followed by highlighting 1033. If you are using the Classic Layout rather than the XP Layout, use number 38. The right hand pane will display the stringtable. We’re going to modify item 578, currently showing the word “start” just as it displays on the current Start button.

There is no magic here. Just double click on the word “start” so that it’s highlighted, making sure the quotation marks are not part of the highlight. They need to remain in place, surrounding the new text that you’ll type. Go ahead and type your new entry. In my case I used Click Me!

You’ll notice that after the new text string has been entered the Compile Script button that was grayed out is now active. I won’t get into what’s involved in compiling a script, but suffice it to say it’s going to make this exercise worthwhile. Click Compile Script and then save the altered file using the Save As command on the File Menu. Do not use the Save command – Make sure to use the Save As command and choose a name for the file. Save the newly named file to C:\Windows.


Step 2 – Modify the Registry

!!!make a backup of your registry before making changes!!!

Now that the modified explorer.exe has been created it’s necessary to modify the registry so the file will be recognized when the user logs on to the system. If you don’t know how to access the registry I’m not sure this article is for you, but just in case it’s a temporary memory lapse, go to Start (soon to be something else) Run and type regedit in the Open field. Navigate to:

HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon

In the right pane, double click the "Shell" entry to open the Edit String dialog box. In Value data: line, enter the name that was used to save the modified explorer.exe file. Click OK.

Close Registry Editor and either log off the system and log back in, or reboot the entire system if that’s your preference. If all went as planned you should see your new Start button with the revised text.
