I've just discovered that all my Windows retore points have been deleted. After a few tests I found out that CCleaner did it. To comfirm that, I created a restore point and then ran CCleaner: the restore point was deleted. If I create more restore points they are all gone after executing CCleaner. I think that was not suposed to be so, since I found no option about restore points in CCleaner.
I'm using version 1.28.277. This is the CCleaner log when 2 restore points were deleted:
