Hello, New PC running Win 8.1. Transferred apps and files from old to new PC. I've used CCleaner for years. No issues. With new PC I have latest CCleaner version downloaded from Piriform. CCleaner progresses to 21% then gets stuck for hours cleaning the Systems Empty Recycle Bin folder. If I de-select that folder it runs and cleans fine and finishes quickly. , But if I have System selected, it gets stuck unusually (3 hrs) too long stuck on that folder. Should I leave CC running overnight? Any suggestions, please? Thanks.
