I have a 111GB SSD. Out of that, I had about 500MB free. I have moved all the applications that I can to other drives, deleted temp files and have been over AppData folder. From AppData I'd guess it's still possible to squeeze out a GB or 2.
Running disk cleanup as admin says that windows update cleanup could give me 45GB of free space. But it's not deleting anything.
At first, it was ending in an instant and nothing changed. Then I did all the pending updates, then at least it took some time to finish, but still, nothing. I disabled hibernate to gain some extra space, and tried again, still nothing.
It seems that disk cleanup does not want to remove them, even though they are obsolete. I'm out of disk space on my C: drive, and this is the last place to gain some space. How can I make it remove the old updates?

, as Windows 8.1 doesn't get new major upgrades. See link for how.
