I use Firefox browser, and have with CCleaner Pro won't clean Edge, but from help page https://www.ccleaner.com/docs/ccleaner/troubleshooting/how-to-disable-pre-launching-and-pre-loading-so-ccleaner-can-fully-clean-edge i do not find the Registry entry for Microsoft EDGE, HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main , What to do next, as I may if possibly have deleted or put edge to sleep EDGE. Do not use Internet Explorer either. Not seeing folders for Preload or Tabs.
