Horinius - you have to reboot for the clean up to occur. WHen I did, it cleaned up the amount of disk space that the Cleanup manager said, but my winsxs folder had about 8 GB more, most of which is files and folder that at 3+ years old. My theory is that
this is garbage that my IT department left behind when they build the standard image.
Anyone know how to delete the rest of the trash in WinSxS?
Of course we have to reboot for the clean up.  Did I say we didn't have to?
If you want to do the "Windows Update cleanup" (as specified in the original post), there's no need to use this "Cleanup manager".  You just need to open "C:\Windows\SoftwareDistribution\Download" and delete everything inside it.
