Thanks! Your tool just freed over 50 GB on my 120 GB SSD! Everything was Office 2013 related and I'm running Windows 8.1.
Nice tool My installer folder has historically been 3GB. Yesterday I clean installed Windows and then installed office 2016 and lost 8.5GB of disk space. I've installed O2016 several times and that has never happened. The installer folder is 5GB. After running this script I got back 1.5GB of space, so I don't know where the other 7GB went. Installer folder is now 3.5GB 78 patches were uninstalled, which confuses me as only 40 had been installed? The script also offered to uninstall an Acrobat patch which I installed to fix a bug where Acrobat drops to the desktop about 10 seconds after opening a pdf file. Fortunately it didn't uninstall it. Great work though!
