How To Find Directories That Are Taking Up Space On Your Hard Disk
Follow the windows tip of using diruse. click
Turns out a hidden folder called C:\WINDOWS\Installer contained 21GB of data, used for uninstalling and repairing installed programs. Most of this data appears to be either duplicated or from software that didnt unstall correctly. It is not safe to delete this data, so I downloaded the Windows Installer CleanUp Utility tool as recomended.
It turns out that the tool itself dosn’t help, but comes bundled with an unsupported command line utility called MsiZap.exe which can remove orphaned files.
Usage
C:\Programme\Windows Installer Clean Up\MsiZap.exe G
This deleted 99% of the data without affecting anything else. I now have around 400mb of data in the installer directory which shounds about right.

Thanks.
I had about 13Gb in that C\windows\installer directory. Cleanning it that way removed 9Gb. I still have 4Gb wich is far less than before. For now it is something that I can live with.

Same problem again on the same laptop a year later. This time 16GB of data gone in one command. Still no idea why that happens.
