Why when I run CCleaner Professional does it SKIP Microsoft Edge and Internet Explorer folders?. They are checked on the Windows tab.
g'day jhill and welcome to the forums.
it'll skip any browser that it detects as open or running in the background, and for Edge and IE that also relates to anything shared with Microsoft libraries they use between other products; so potentially things like OneDrive, Skype, Defender etc.
Be sure to turn off background running of edge
