Whats the "safest" way to clean up large files in the Windows Installer cache? Is deleting the files the only way, or is there a better way to "unregister" the cached files or something?

You'll want to be careful about this. The cached installation packages may be necessary for installing application patches, uninstalling certain applications, or repairing applications and the OS.
However, if your computer is running well at this point and having more free HDD space is more important than being able to remove patches or repair applications, then CCleaner is the tool you'll want to use.
In Windows XP, in the Cleaner tool in CCleaner, in the Windows tab, 3rd from last option should be "Hotfix Uninstallers".
In Windows 7 you cannot remove the OS patch cache because it isn't really quite the same thing anymore and cannot be handled the same way. But it also doesn't store nearly as much info. If you hadn't noticed, Windows 7 patches tend to be much smaller than comparable WinXP patches due to efficiencies developed in the patching system for 7.
CCleaner cleans up the patches? I'm not sure where to find the option... – user541686 – 2011-10-14T19:55:31.217
What OS are you running? Please update your question with that info. – music2myear – 2011-10-14T19:57:01.927
Windows 7; updated. – user541686 – 2011-10-14T23:43:08.280
Then you're talking about the C:\Windows\WinSXS directory? – music2myear – 2011-10-15T15:12:14.167
Uhm, no. I'm talking about C:\Windows\Installer
, which behaves the same way as in XP. – user541686 – 2011-10-15T19:21:09.847
Can't find the option either. – fschmitt – 2013-09-05T13:43:22.807
As I stated in the answer above, if you're running Windows 7 you will NOT see the option to clean up Hotfix Uninstallers in CCleaner. This option is ONLY available when running Windows XP (I have not tested with pre-XP versions). – music2myear – 2013-09-06T16:29:26.583
CCleaner is a good, safe tool for cleaning up unneeded files on Windows. I don't know if it specifically cleans the installer cache, but if anything will do it safely, CCleaner should. http://www.piriform.com/CCLEANER
