So the Windows\installer folder (and the WinSxS folder, but that's another story) is eating up quite a LOT of space on my hdd. Windows Installer Cleanup utility was the tool of the trade before, but now Microsoft zapped it with the reason that it's insecure and might delete something that shouldn't be deleted.
So my question is: If I shouldn't use this tool to try freeing some space, what else? My Windows directory is, alone, using like 25 gb. Most of it comes to the installer and winsxs folder.
