System event broker stopped working on my windows 8.1 64 bit laptop. Going to services it says that it's startup is "automatic", but trying to start it gives me this message:
Error 1058: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
Task scheduler is dependant upon system events broker, and since it stopped working I havn't been able to install ANY drivers (Error: Invalid data) and my networked folders stopped working.

How do I enable / start System Events Broker?
