I agree. This Windows version runs every application I'm using with no apparent problem. However, I still get dozens of messages continuously from Windows 10 Update Assistant that "This app can't run on this device" without telling me which application is the problem. It will be a pain to change every application to run in Compatibility Mode. When I check Task Manager, the only applications I see are Firefox, Notepad and Program Compatibility Assistant which doesn't seem to help define the offending app. Any idea how I can find out which application it doesn't like?
