So, from an online tutorial, I learn about this software called "Winternals ERD commander" bootable CD to hack into your own PC, and reset the password if you want. It is a pretty good tool if one day I forgot my password to my laptop. So, what other usage from this software, does anyone know? Is this software only used on Win XP, what about Windows 7, or Vista? I have the version with Year 2007, can it be used on Windows 7? If anyone can show me how to used it?
