The software program PE Builder can be used to create a Bart's Preinstalled Environment disc, or BartPE, which you can use to boot your computer from a disc. The bootable CD also enables users to write and read files to their computers' hard drives. You can use this program instead of WinPE to restore operating systems. One feature of the BartPE program is the ability to reset your Windows administrative password. If you must have access to an administrative account to make program changes, you can use BartPE to reset the password.
