Hi All,
None of these suggestions worked for me so I turned to an 'old culprit' called UAC (User Access Control).
As soon as I turned UAC off streaming remained on between reboots!
Of course there is a trade off in W8, and W10 in that Store Apps will not work with UAC off. In my case this wasn't too great a concern, because I am using traditional programs, however you may want to keep this trade off in mind.
I hope this helps.
Kind Regards,
Davo
