I'm on Win8.1 64 bit and on CCleaner v4.15.4725 (64 bit) Pro. When I click <Run Cleaner> it does its job and for System - Empty Recycle Bin it shows that 685MB and 122 files were deleted. When I open the Recycle Bin in Windows it is empty. When I execute <Run Cleaner> again, the same cleaning results show up again. When I view CCleaner's detailed results the exact same files show up. This started to happen on v4.13, and the patch to v4.15 did not make a change. Can you please provide a solution?
Sounds like you may have a corrupt recycle bin, see here

That did the trick. Many thanks, Hazelnut !
Glad you are sorted now Bluefoot
