POWERFUL WINDOWS LOCK
Most Powerful Windows Lock
Commonly we can find a user lock in the welcome screen in windows which can give a hint when asked for, A second or third option for logging is also available in windows 8 or windows 8.1 but there is another lock which will neither give you a hint nor any kind of different logging options. The only thing you have to do is not to be dunked and enter the password in syskey lock or SAM lock Tool
after entering the pasword and restarting you will be able to see a box asking for password before the welcome screen appears.. It dosens’t have any password hint..nor any other sign-in options availabe..
you can find syskey in windows 8 by winlogo+s and then typing syskey..in older version goto run and write syskey then enter..
if you forget its password the only option that would be available to you is FORMAT..
so please handle with care
