Slightly more work needed if you lose or forget the Windows XP administrator password.

1.First reboot Windows XP in safe mode by re-starting the computer and pressing F8 repeated as the computer starts up.

2.Then (in safe mode) click Start and then click Run. In the open box type "control userpasswords2" without the quotes - I have just used quotes to differentiate what you have to type.

3.You will now have access to all the user accounts, including the administrators account and will be able to reset the lost password.

4.Just click the administrators user account, and then click Reset Password.

5.You will need to add a new password in the New password and the Confirm new password boxes, and confirm by clicking OK.


All done, you have recovered the lost adminitrators password!

Many times Windows users face a common problem. The “Folder Options” in “Tools” menu is not visible. Even It can’t be accessed from Control Panel. Also “Registry Editor” is disabled.
Follow the simple steps mentioned in this tutorial and your problem will be solved:

1. If Folder Options is disabled but Registry Editor is still working in your system, then you can enable Folder Options by editing Windows Registry.
Type regedit in RUN dialog box and press Enter.
it’ll open Registry Editor, now go to following keys:
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\ExplorerHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\Explorer
In right-side pane, check whether a DWORD value named NoFolderOptions exists or not? If it exists, delete it.

2. If you are not familiar with editing the registry, then you can simply download following file, extract it and then run the .REG file:
Folder_option.zip

If u cant run regedit ....

Boot up with DOS and delete the sam.exe and sam.log files from Windows\system32\config in your hard drive. Now when you boot up in NT the password on your built-in administrator account which will be blank (i.e No password). This solution works only if your hard drive is FAT kind.
