When you uninstall a program sometimes they make a mess and do not clean up after themselves. Programs sometimes leave behind code fragments and registry settings that can slow down your computer or prevent other programs to run properly.

Microsoft’s Windows Installer CleanUp utility can clean up  the mess these programs leave behind. The program is free from Microsoft support and it can be downloaded from their support website. It will allow you to remove the messy program and allow you to reinstall the program if needed. 

The Window Installer CleanUp Utility works with all versions of Windows including Vista.
