I have an Excel icon on my taskbar. when I right click I get all my recent files. When I run CCleaner it deletes them. In Excel I have a high number as the number of previous files to show.
You can still see the recent files in Excel so the list is still there.
On the 'Windows' tab in CCleaner look under 'Windows Explorer' and untick 'Taskbar Jump Lists'.
That's the setting that removes those 'recent' lists from the taskbar icons if it is ticked.
thanks. that was too easy
