Download.com Staff Feb 27, 2009
If your Registry is as cluttered as grandma's attic, you'll find WinASO RegDefrag a simple and free way to do spring cleaning. Just press a couple clearly marked buttons, and restart your computer if necessary when the process is completed. Don't expect a dramatic change, but you may free up a bit of disk space and slightly improve your computer's response time.
