I did a quick search and couldn't see this, but apologies if this has already been posted.
It would be very helpful if items which are pinned in "recent file lists" (such as recent files in Excel/Word etc) are not removed during the cleanup operation.
Why can't we get a check box to remove files from the Recent list in Office applications? Is that the only thing CCleaner cleans from Excel & Word? Do really long recent files lists in Office applications slow down your computer? If so, perhaps the user could be prompted to clean them, if you don't make it an option.
Otherwise, CCleaner is cleaning something that I don't want cleaned. Surely I'm not the only one. There are folks out there wondering why their recent files list has disappeared, as evidenced by this post...
