Windows XP forgotten password | Unlock My Password
The developers of Unlock My Password software created a three-step process that quickly allows the computer user instant access into their Windows-based PC. The technician or computer user can use an accessible Windows based computer to download the software application. Next they will be required to copy the software file onto an auxiliary storage device such as a CD, DVD or USB stick. Finally, when a login issue arises, the technician or user simply inserts the storage device into the accessible computer and reboots.
