100 % fIX for error "Windows Audio cant be started, Error 0x800706cc: Endpoint is a duplicate" HD

The problem is mainly because of AVG antivirus which reads the system audio service file as a virus file and places it in the quarantine zone..i fixed it by uninstalling the antivirus and furthering proceeding with this fix.. Please lemme know of any problems u face while fixing ........ Navigate to HKLM - SYSTEM - CurrentControlSet - Services - AudioEndpointBuilder - Parameters Check the ServiceDLL data, on the problem system it was: "%SystemRoot%System32Audiosrv.dll" It should be: "%SystemRoot%System32AudioEndpointBuilder.dll" After a reboot of the system, all sound was back and the services were started with no errors.
