There are always some people who find pleasure in snooping into your computer screen and see what we are doing. What you can do to prevent such people from looking at your screen is to lock your screen with a free software called ScreenBlur. This is specially useful at work.

If a file is in use by a program or Windows itself, then it cannot be deleted as long as the program is using it.

Sometimes when you try to delete a file in Windows, it fails to be deleted no matter how many times you try.

This freeware tool can set any locked file to be deleted on Windows restart.
