Just updated and rebooted. Action Center reports both Avast and WD are off (Avast is on and reports all is good) and gives a button to view antivirus options. Hitting that button gives me the attached dialog that Windows cant monitor Avast if turned on. Same thing for anti-malware protection.
I have had this issue as well. Happened in the beta’s frequently and on odd occasion during RC1 and RC2 but not RC3.
Last correspondence a while back, when this happened in V8 was devs were looking into it…
This not only happens in W864 but also 8.164
Hopefully the devs are continuing to work out why this happens.
It usually takes one or two more reboots to fix that… I know, it’s strange, but I have seen it too many times to not believe it.
The Windows Action Center seems to be somehow caching the information.
