Recover windows passwd with this simple trick
Boot off the Windows disk (if you don’t have one, you can make one) and select the “Repair your computer” option from the lower left-hand corner.
Follow through until you get to the option to open the Command Prompt, which you’ll want to select.
copy c:\windows\system32\sethc.exe c:\
Then you’ll copy the command prompt executable (cmd.exe) over top of the sticky keys executable:
copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe
Now you can reboot the PC.
Once you get to the login screen, hit the Shift key 5 times, and you’ll see an administrator mode command prompt.
Now to reset the password—just type the following command, replacing the username and passwd with the combination you want:
net user geek MyNewPasswd
That’s all there is to it. Now you can login.
