You don't really have a problem.
First go to AMD's driver site and grab the latest driver for your 280.
go to this page https://support.microsoft.com/en-ca/kb/3073930
and near the bottom is a link to wushowhide.diagcab
run that and hide AMD driver updates.
That should stop MS from wrecking things. IF MS happens to install it's update before or just after you run this (updates can get caught in a que) simply go to device manager and roll back the driver for the vidcard.
Many thanks to you also. So glad I've got something to try instead of blocking all driver updates in W10. Much appreciated. Truly.
Thank you kindly for that. I shall try it. Sorry for the late acknowledgement to your post but I've been on holiday. Much appreciated :-)
