Wndows connot connect to event notification service!

Few days suffering from this error : "Wndows connot connect to event notification service" to resolve that :

1. Reboot your computer into Safe Mode (with Networking).

 2. Open regedit and delete the following two keys and all their subs: HKLM/System/CurrentControlSet/Services/Winsock HKLM/System/CurrentControlSet/Services/Winsock2

 3. Reboot your computer again and let it start up normally (non-safe mode). voilà!
