Avoiding of cleanup of MRU lists

Hi, can I get a clue what to exclude to avoid cleanup of MRU and windows dialogues history lists?

Having exception for registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32 but it wnyway doesn't prevent cleaning up MS fileopen dialog history. Do the exclusions apply recursively for any subitems or only for that folder?

You should be unticking and/or excluding these recent file lists in the cleaning section and not in the registry section.

Registry clearing is a different function and is not recomnended as a regular practice.
