ClearLock

ClearLock is a simple application that allows you to lock your desktop (like when you set the screen saver password), while you can still see what is in it.

Thus, you will be able to leave your computer while it is downloading, defragmenting, or performing any other task that requires a lot of time, while your desktop is locked.

The computer will be restricting the access but you'll be able to see what's happening. We could say it is as a transparent password protected screensaver.

The only problem, which would usually be a real advantage is that the program requires no installation and it is impossible to integrate it in Windows. You'll have to double click the executable every time you want to use it, so if you want to use it often, place the shortcut in an accessible place.

ClearLock is an interesting tool for any user who values his privacy and don't want other people using his computer. They'll password protect the computer in just one click.
