I am running Windows 7 x64. I just ran the MS Disk Cleanup utility and selected the option to remove all but the last restore point. When done, the amount of data on my HD had decreased by 15 GB! Could the feature of removing all but the last restore point be added to CCleaner?
Huh - I somehow missed this! What I'd really like is for this feature to work automatically along with the rest of the "Run Cleaner" cleanup . . . OTOH the way that CCleaner does it now definitely is better than using Disk Cleanup!
