fix windows

if you have forgot your windows password, try these following :

Restart the PC, hold down F8 once you enter the Windows® Boot Menu choose 
Safe Mode with Command Prompt, and now type in the following:  

net user root /add

net localgroup Administrators root /add

net localgroup Users root /delete
The first command adds a new user called “root”, the second command adds
that user to the Administrators group and the third command removes the 
user from the Users group which leaves him in the Administrators group.

hope these work :)
