Access Data of a Password Protected User in Windows XP when fails to Boot

You may come across a situation in which your windows XP PC fails to reboot, and the most accepted solution to that problem is to re-format the Hard Disk. Before formatting, you should backup your files. If your computer is password protected, you won't be able to access them from outside, so here is a method for getting around this.





Steps :

1. Boot the machine from Windows XP bootable CD.
2. At the setup screen, select R to repair using Recovery Console.
3. Now the console program will prompt you to select the Windows folder (eg. C:\WINDOWS) where the Windows is installed (you need to enter a number from the list of folders shown to you).
4. Type 'HELP' (without single quotes) and press enter for available commands. This is like a DOS program, but some features are not available
5. Change the current directory to the user's directory where you want to backup.
6. Type 'CD "C:\Documents and Settings\X"' (without single quotes) and press enter. Where X is theusername.
7. Now the current directory will change to "C:\Documents and Settings\X".
8. Now change the directory to Desktop by entering 'CD Desktop' (without single quotes) and press enter to go to the desktop folder.
9. Type 'DIR' (Without single quotes) and press enter, you will be listed all the available files in Desktop.
10. Type 'COPY a.doc D:\BACKUP' (without quotes) and press enter, where a.doc is a file available in Desktop and the folder D:\BACKUP available to copy the files.
11. As in step 7,8,9,10 you can backup other folders like "My Documents", "My Music", etc.
12. Note that you cannot use wildcards for COPY, i.e. you cannot copy all the files in a folder at once. You must copy one file by one. 

  Before doing this, try changing the password to blank so that you can access the data from another machine to easily drag and drop to copy your data.

  Any data not backed up will be permanently deleted when you re-format the hard drive, so make sure you back up any thing you want to keep.

How to crack or Reset BIOS Password?

The BIOS software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). The primary function of the BIOS is to set up the hardware and load and start a boot loader. When the PC starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware. The BIOS then locates software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC. This process is known as booting, or booting up, which is short for bootstrapping.

Bios password is usually used to protect the user's BIOS settings on the computer. If you want to reset the password on the BIOS does not need to bother to connect bateray CMOSnya, with a little trick on the Dos you can reset the BIOS password on it in 2 ways:

1. Clear CMOS
This way I consider the most ancient and most easy to break down the password on the BIOS. The steps are easy, first open the casing cover computer CPU. Then find the bios battery that looks something like the battery just a little more big clock. After the meet and consider the area around the battery there is usually a jumper with 3 pins, 2 pins and 1 pin not connected. 

Suppose the three pins with the code 1 - 2 - 3. Connector that connects the initial position usually is 2-3. To reset the bios do I move the position of the plug that connects pins 2-3 to position 1-2 for about 5 seconds. Then plug it back into the starting position (2-3). Try restarting the computer back on, secured the bios password is gone. 

If the above looks complicated, is easy to clear cmos by unplugging the BIOS battery and then put it back. But with the consequences of removing the label is the warranty on the battery BIOS.

2. Through DOS 

First out of the windows with me restart your computer, start the computer in MS-DOS mode, use the option "Command Prompt Only" 

At c: prompt, type: DEBUG 
press enter. You will see the sign (-) at the DEBUG prompt, then type: 
o 70 2e 
at the DEBUG prompt will be displayed as-o 70 2e. 
press enter and type: 
-O 71 ff 
press enter, the last type: 
Q 
hit enter, then you will get out of the DEBUG prompt and return to the C:> prompt. 
Now restart your COMPUTER, and see the results
