You've been a good boy or girl, and you regularly update your system's drivers. In theory, that should keep your system in tip-top shape, and running at peak performance.
But there's a downside as well: If you don't properly remove your old drivers, they can cause system instability, slowdowns, hardware woes, and system crashes.
Driver Sweeper to the rescue. This clever little utility does exactly what it says. It sweeps through your system, finds old drivers, then lets you remove them. For safety sake, it backs them up as well, so that you can restore them, if need be.
