I thing the title is clear.how to block you're windows and you cant do anything just after typing the correct password or you will reboot you're computer.To do this trick you need a smale software cold ''CLEAR LOCK''and it's easy to use.

after downloding this software it will look like a 2 folder "x64" and "x86"

so if you have 1 gb ram or less open "x86" folder and "clearlock" and type you're password.

If you have more then 1gb of ram so open "x64" and do the same.
