Clean the Windows Installer Folder


The c:\Windows\Installer folder contains windows .msi installers and .msp patch files that are used when installing and updating software on your windows computer.

Over time as more and more programs are patched the size of this directory gets very large and some of the files are actually orphaned and no longer required on your system.

The problem is you cannot just delete the entire directory as these files are used when upgrading or uninstalling your software. What you need to do is only delete those files that are not in use any more


Patch Cleaner

This is a simple piece of software that will clean your windows installer folder in one easy click.



If you are unsure of the program just use the move function to move the detected orphaned patches off onto an external drive. If the program has done something wrong you can just copy them back.

This software is 100% free. >> Download Here <<

    “PatchCleaner has stopped working.
    A problem caused the program to stop working correctly.
    Windows will close the program and notify you if a solution is available.”

    Ant ideas? Im running Windows 7 Ultimate 64 bit
