Today as I was installing the latest and the greatest I got a annoying warning telling me I was running out of disk space on my C-drive. I quickly started up the very useful tree size tool. Using this I was quickly able to establish that most of the used disk space was coming from the C:WindowsInstaller folder. As much as 24GB was taken up only in this folder!

Make sure you DO NOT DELETE or empty this folder. This folder is needed for uninstalling and upgrading programs and service packs on your pc. However there is another tool which can easily help you determine which files are still in use and needed and which ones can be safely removed. The tool is called WICleanup. While this tool worked perfectly for me, I advise to use it at your own risk as I am not the author of this tool and thus take no responsibility for it.

You can launch the UI version of the tool which will provide you the following interface:

After pressing the scan button you will get a list of all files which can safely be removed. While you can select multiple lines at once (using shift combination) and check all lines, we do advice you to use the command line version of the tool is you want to remove all of these files at once. In the UI you will get an annoying pop-up to confirm the deletion of each file, which does not make this very usable.

Instead you can open up a command prompt, go to the directory where the tool is installed and type in the following command:

WICleanup.exe -s

Once done you can confirm this by running the same command again.

This saved me 18 GB of disk space 🙂
