I have a Widnwos XP pc has the update problem as below:
When attempting to run Windows Update the following message appears: ‘Error number: 0x8DDD0018.’ This message states that the Automatic Updates, BITS, and Event Log services must be started, but they are all started and WinUpdates still fails.
First I know, this pc has kind of virus or spyware. I clean them and make it looks OK. But still can not update.
Later I find the post and the solution.
run command from command window.
regsvr32.exe wuaueng.dll
After it, enable the service above and run windows update. Works.
