Didn't notice the duplicate tree rules list. I just opened CCleaner and I see that both WINDOWS and APPLICATIONS rules lists are duplicated.
See attached screen capture.
No.
When I click on / open CCleaner from desktop icon / link the window presented is clear/blank only the left tree is displayed, after clicking the Analyze button, the list is presented. As mentioned in OP, duplicate references occur intermittently.
Home screen = Custom Clean; see attached screen capture
NOTE: CCleaner has been updated to 5.78.8558 (64-bit)
No.
There are no custom or saved .INI files.
See attached screen capture showing Options=>Advanced settings along with directory window displaying CCleaner install folder
- peace,
