Quickly Lock Your Windows - Keyboard Shortcut

There are many ways to quickly lock your Windows and the soul purpose of doing that is to protect your computer from anyone's access. At offices you should lock your Windows so that when you are not at your seat, no one else can take a look at what you were doing or they cannot steal anything from your computer and beleive me you should do that (make it a practice). To make it more secure, you can lock your PC with a single click and Unlock It With USB.   

At
home, if you have a movie or a program running on your computer that you want
your kids or your brother / sister to see while you are away and also dont
want them to mess up with the computer, then you can transparent lock your desktop which will help you a lot.
The traditional method to lock your Windows is to press CTRL+ALT+Delete button
and than select Lock
this Computer option in Win 7 and Lock Computer option
in WinXP.
In WinXP

in Win 7

Though it's already a very simple and easy method but still it takes a bit time to bring that option on your screen. In order to make the whole process more fast in 1 click, you can simply press WIN Key (windows key) + L.By pressing that combination, it will immediately lock your computer in a second. I found this keyboard shortcut quite an effective way in order to lock my windows quickly.
