Large amount of HD space (70%, 136gb) and increasing, is being used by System Volume Information on Windows 7 Pro. I ran Windows Cleanup System Files several times. Most it reduces is 2 to 4 gbs. Considering the size of usage, the cleanup amount has virtually no impact. I got no help from Microsoft. I don't want to fool around with manual deletion or cleaning. Since Daniweb is the the most extensive, from a professional aspect, on the web, I'm hoping someone here can help.
