I am running out of space on my C: drive on my Windows 7 machine and using JDiskReport to analyse where the storage is being used I find these big ones:
C:\Windows\winsxs: 24.5GB (of which "Other" is 21.8GB)
C:\Users\All Users\Package Cache: 5.4GB (most in "Other")
Are any of those targets for either deletion or some form of cleanup?
Is there a utility that could get rid of anything *really* not necessary (and that won't break my system)?
