Except Universal apps are entirely new for Windows 10 -- so it&#x27;s an empty and new platform that sits alongside regular Windows applications.  Developers have to go out of their way to develop for this separate platform in a platform and, from what I&#x27;ve seen, they aren&#x27;t.  I&#x27;m still running Windows 8.1 on my devices so I can&#x27;t even run these universal apps.
