Tested on: NT 3.51, NT 4 (all versions and SPs), Windows 2000 (all versions & SPs), Windows XP (all versions, also SP2 and SP3), Windows Server 2003 (all SPs), Windows Vista 32 and 64 bit (SP1 also), Window 7 (all variants). Some also say that it works on Windows Server 2008 too.
If used on users that have EFS encrypted files, and the system is XP or Vista, all encrypted files for that user will be UNREADABLE! and cannot be recovered unless you remember the old password again. If you don't know if you have encrypted files or not, you most likely don't have them (except maybe on corporate systems).
Follow the steps for resetting your password:
1) Boot your computer from Hiren’s BootCD. Follow the steps in change the boot order in bios document if you are having problem to do that.
2) With Up & Down keys select "Dos BootCD" and press Enter on the main menu of Hiren's BootCD.
3) And then enter "Password & Registry Tools ..."
