Last week before long ied holiday, my PC got an error after I updated windows. “Failed to initialize MainWindow A socket operation encounterd a dead network”.
Because this problems I can not connect to all network include LAN and wifi.
I guess I can resolve this problem by using system restore, but sadly it can’t. After long hours find the solution I found one on social technet thread
Just using command on CMD
the process takes time maybe 5-15 minutes, after that I have to restart my PC and voila! My PC can connect into network again.
