Today after finish upgrading PC to windows 8.1, I found windows update service not started.
When i tried to start it, it prompt “Windows could not start the Windows Update service on Local Computer“, “Error 0x8007277a: The Requested service provider could not be loaded or initialized”
I just kept searching internet and running below commands in elevated command prompt solved the issue easily,
netsh winsock reset hit enter
netsh int ipv4 reset hit enter
netsh int ipv6 reset hit enter
Then just restart windows and everything went fine
