Running an HP Envoy 700-214 with W8 factory installed, did add the Pro 8.1 CD-ROM direct from MS solely to have Windows Media Center---all that is working perfectly.

The occasional pop up band pushing the 8.1 upgrade is annoying. This machine is NEVER online--NEVER and will never be since its mostly a media player/recorder. Is there a particular KBxxxxx update I can disable to stop this annoyance?
