PatchCleaner 1.4.2.0

[tarekma7]

When applications are installed and updated on the Windows Operating System a hidden directory "c:\Windows\Installer" is used to store the installer (.msi) files and the patch (msp) files. These files are important as during updating, patching or uninstalling software. If you blanketly delete all the files in this folder, you will find yourself needing to rebuild windows. Over time as your computer is patched and patched again, these installer files become outdated and orphaned. They are no longer required, but they can take up many gigabytes of data. PatchCleaner identifies these redundant/orphaned files and allows you to either, move them to another location; or Delete them. You will reclaim GB's of space. Most users of older machines reclaim between 5Gb and 10Gb, the best I have seen reported is over 20 Gb.
 
How it works:

HomeDev has had many queries about how PatchCleaner works and if it can be trusted to do the right thing.
Its pretty simple. The windows operating system holds a list of current installers and patches, that can be accessed via WMI calls, (Windows Management Instrumentation ).
PatchCleaner obtains this list of the known msi/msp files and compares that against all the msi/msp files that are found in the c:\Windows\Installer directory. Anything that is in the folder but not on the windows provided list is considered an orphaned file and is tagged to be moved or deleted.
HomeDev cannot warrant that PatchCleaner will not find a false positive and delete a required patch which is why we recommend using the move feature, that way you can always copy the patches back if required. Please see the Known Issues List at the bottom of the page
