Do you feel like you need to change things up a bit on your Windows machine? The free Logon Screen Rotator is able to give your logon screen a fresh new look each time your computer starts up. That way the next time you go to login you'll be surprised with the background that is there to greet you.

Windows can be configured to lock your computer after the screen saver kicks in, which means when you return you'll need to login again. The security this offers is nice but it's not very customizable, and one such example is that you can't easily the screen to turn off and lock the computer at the same time.

If you're one of those people that have to suffer with a PC that takes minutes to boot up this is something you'll want to consider doing. It can be frustrating when restarting a computer that takes forever because many times you can't just walk away and come back to it ready to be used.

Most people carry a USB drive around for storing files on-the-go, but that's not all they are good for. A free (for non-commercial use) program called Predator will actually let you use a USB drive as a key for your computer. Basically, when you remove the drive the computer will lock itself, and it will be unlocked the next time you insert the drive.
