I have Windows 10 version 1511, I had rolled back the anniversary update. On 10/14/16 a security patch KB3192441 was applied and that patch prevented my WMC from seeing my cablecard tuners. I am running the WMC 8.8.1 mentioned in previous posts. I have not tried to reapply the anniversary update and see if WMC 8.8.1 works like TulsaTV mentioned. Has anyone seen similar behavior with the recent patch and has anyone else gotten WMC 8.8.1 to work with the anniversary update? - Thanks
