The USB Windows Icebox is a device that looks like a flash drive, but it can do a lot more. It has a unique ability to plug into your computer, and it will immediately “freeze” any changes on the hard disk. So another user can jump on to your laptop or PC, but after you turn it off, your computer will return to the state it was in before you stuck in the Icebox.

This is good for parents who have kids who love to play on their mommy or daddy’s computer. The little tykes can do anything they want on purpose or accident, and the parent can simply turn it off at bedtime to eradicate any non-parent approved changes. All of this for just $18.99.
