A relatively easy way unlock a PC laptop after forgetting the password is to use the Windows installation CD to reset the password. However, when using this method, expect to lose all of the data on the laptop. Another method to unlock a laptop is to use a password reset disk. Though this is the best method for unlocking the laptop, it is only possible if the creation of this disk already took place. For some users, it is also possible to use Windows Password Genius, but it has to download before the lockout occurs.
Restoring the laptop to factory mode unlocks a laptop without a password, but it takes the laptop to factory settings. This erases all of the data on the laptop, and the Windows system is then totally clean. A final method for gaining access to a laptop without having a password is to restore the laptop to a time when the password was not on the system. Depending on how long it has been, however, the restoration may not be practical.
