Hi, I'm using CCleaner, and before this last version, the cleaner removed recently used files which I opened using Microsoft Word. Since the update, it has stopped removing them, even though I have the "Remove Recent Documents" option checked. Please note that this happens with any application, not just Microsoft Word. Here is some technical information you may find handy.
Operating System: Windows XP Home SP2
CCleaner v2.06.567
If you need anything more, please let me know!
Thanks!
