Lock your computer in 2 secound

Very useful when you have to leave your system on for some time and you have to go some where else...

Right click on an empty area of the desktop and choose 'new' then 'shortcut.' The create shortcut wizard will open. in the

first text box, type '%windir%\System32\rundll32.exe user32.dll,LockWorkStation' and then give your shortcut an

appropriate name on the next page, and hit 'finish.'

You will notice that the shortcut you created has a blank icon. To select a more appropriate one, right click on the

shortcut and hit 'properties.' In the 'shortcut' tab, click the 'change icon' button.

else u can simply press the "window key + l" to lock your computer...
