How to Perform a Clean Install
Programs installed on a computer sometimes become corrupt and freeze due to system updates and changes. When these programs are uninstalled with a basic uninstallation process, they leave registry values, settings and files that have to be removed before you can perform a clean install or reinstallation. With a free, easy-to-use registry cleaner, you can easily remove all corrupted leftover registry values before performing a clean installation to ensure that the clean install will not be affected by the previous corrupted settings.
