I'm not sure if this is new topic worthy, or if I should just reply here.
I upgraded from windows 8 to windows 8.1 and ccleaner marks about 5 GB of files for deletion. I checked my c drive, and the windows.old file is 4.4 GB
What could make up that difference of .6 GB? Unused .net files or something? I tried looking at the files marked for deletion, but since there are 124,000+ files, I couldn't really sort through.
Should I delete it and trust in ccleaner? That's a good amount of space on my SSD (its fresh so not many programs on it at the moment).
I double-checked what was in the windows.old users folders and didn't see any files, so I doubt it would delete any important things.
