I work a lot with my Taskbar in Windows 7. I have lots of files/documents and folders pinned to the Taskbar. When I run CCleaner, however, it deletes not only my recent files, but also those pinned files/documents and folders. Why is that? What option(s) must I select to prevent that from happening? If this is a known bug, is it being worked on? Any input would be awesome and most appreciated. Thanks!
