There are several good and safe registery cleaners available. Check them out at cnet.com and other software review sites. If you reinstall windows, you will lose all your music and folders that you put on your pc and start with a "clean" machine. It is easier to clean out "junk" using special software such as System Mechanic. It will do the work for you after you tell it to.
