No one has the PC's admin password
If the wrong person leaves your company in a huff, one or more PCs could be left stranded. With no one in the company knowing the password to an administrator-level account, you can't install software, change important settings, or possibly access encrypted data.
Fortunately, you can remove the password, letting you log on to that account. You do that with the Offline NT Password & Registry Editor, a bootable, text-based free program that you download as an .iso file. Double-click that file, and Windows 7 will start the process of burning it to a CD.
