Dennis is running Windows 10 on his desktop, and now OneDrive is screwing up Adobe Lightroom. So he uninstalled it and turned off syncing. Now icons are showing up as being "owned" by Creative Cloud. Leo says that sounds like confusion in the icon cache. Leo recommends rebuilding the icon cache to clear the problem. Go into the Adobe Creative Cloud icon menu and make sure they aren't syncing everything. It could also be a registry issue.
Leo also says that the current updates to Adobe Creative Cloud have been a nightmare for users.
