Windows - Installing Windows installer CleanUp utility

Windows installer CleanUp utility software for Microsoft Windows operating systems is made to eliminate uninstalled fragments of programs. The software uses registry references and files related to Windows Installer installed by several programs, and compulsorily wipes invalid entries. It can be used in 32-bit and 64-bit Microsoft OS's. It's to clean up installed programs that either refuse to be, or pretend not to be deleted from the add/remove programs feature in Microsoft Windows.

It modifies registry values and files related with the Windows Installer part. It will not remove most of files on the system but must be used as last option when facing an infected program. The utility is available only with system administration rights.
