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.

This covers general cleaning of a Windows installation. The windows installer cleanup is quite specific though :). Also I'd have refered to all the other questions regarding Windows cleanup then. – sinni800 Jul 11 '11 at 11:20
CCleaner also allows removal of uninstallers and caches for installed updates, which can be a significant chunck of disk space if you've never cleaned them before. – music2myear Jul 11 '11 at 22:11

Try BleachBit This application is similar to ccleaner, it frees cache, deletes cookies, clears Internet history, shreds temporary files, deletes logs, and discards junk.

Use BleachBit to:

  • Free disk space
  • Reduce the size of backups and the time to create them by removing unnecessary files -
  • Maintain privacy Improve system performance
  • Clear applications cache

BleachBit includes a growing list of cleaners. Typically each cleaner represents an application such as Firefox or Internet Explorer. Within each cleaner, BleachBit gives options covering components that can be cleaned such as cache, cookies, and log files.

Could you please edit your answer to include a bit of info about what the software is and how it solves the problem? Just including a link is not very helpful. – nhinkle Jul 11 '11 at 20:00
Also info on how it relates to my problem. I got ccleaner. But does BleachBit also clean the Windows Installer Cache? – sinni800 Jul 11 '11 at 20:49

You can try revo uninstaller. I don't know how good the free version is though.

I don't actually want to delete programs. I just want to clean the Windows installer CACHE. I know that uninstalling programs would also make the cache smaller ;), but this is not what I am asking for... EDIT: Holy crap it does try finding artifacts of not completely uninstalled programs. I'll try it out! – sinni800 Jul 11 '11 at 19:15
I think the "Junk Files Cleaner" option might do what you're asking. – Kevin Qiu Jul 11 '11 at 19:18
Yes, I am testing it now! – sinni800 Jul 11 '11 at 19:30
