Usually, we can recover Windows admin password in two traditional ways.
A.) The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example,
1.) At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window.
2.) Insert the password reset diskette into the computer and click Next.
3.) If the correct diskette Windows XP will open a window prompting for the new password you wish to use.
If u forgot to create Password Reset Disk, then there is still the last way that can unlock your computer without reinstalling – erase Windows password with Windows password reset CD, which can recover admin password for Windows 7/XP/Vista/NT/2000/2003…. Take Windows Password unlocker for example, followings are the steps to create the reset CD
1.Download Windows Password Unlocker from Password Unlocker Official site (it’s free)
2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker.
3.Insert the newly created CD into the locked computer and re-boot it from the CD drive.
4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, this software can remove screen password instantly.
