This software is without a doubt one of the easiest and fastest ways to optimize system performance by cleaning up the Windows registry. I noticed an immediate improvement in startup and shutdown times and programs open faster as well. Overall, the computer just runs a whole lot smoother and it only took a few minutes from start to finish. The interface is straightforward and designed in such a way that just about anyone will feel comfortable using it, and with backups automatically performed there's little to worry about in the way of any problems arising.
