I had not bothered about this for some time - but I thought I had better get it sorted now as I had not updated for a while.
I kept getting the error Automatic Updates, BITS and Event Log services not running. Even if you go to the services list and find that they are running it still does not work.
I found that the problem was with the Automatic Updates service that was not set to start up automatically - probably something I did a while back when I pretty much switched almost all the services off!
Anyway - to solve this problem - right click on the automatic updates service and change its start up mode to automatic, make sure RPC is running and then restart your machine.
That should do the trick!
