Nobody can start your system without U(Only for windows)...

Hello Friends this time i am here for a very interesting TRICk..from this trick nobody can log into your system.
Because here we first create a boot device that will be a pd and without that pd your system will not start.It means some boot up files is into that drive.
So, we send some boot up file into that drive this is our moto & then nobody can start your system untill that drive is not attach with your system. Basically this is for those who got hesitate to say "NO" from giving laptop or desktop to others.

Step 1) Go to run , Then type "Syskey" then this will pop-up.





Step2) Click on Update.





Step 3) Select what u want
