Well Windows Locking is a nice feature presented by Microsoft.
According to this feature, if you are working on a Windows based Operating System, you can lock your PC by pressing Windows Key + L. But what if you need to lock your computer from some distance.
Imagine you are not at your office and suddenly it came in your mind that you forgot to lock your computer, what to do then?
Will you go back there and lock it?
