Windows XP Missing Automatic Updates service
Windows XP Update fails because it is missing Automatic updates service / Automatic update service will not start.
I came accross this when working on a customers machine.
The first thing you will want to do is download the latest version of Dail-a-fix. Run the windows update and MSI fixer. Next you should open a command prompt by hitting: START – run – "cmd". In the command box window type:
regsvr32 wuaeng.dll
This will re-register this service.
EXTRA NOTE – An inplace repair install of XP will not correct this issue.

Very useful tip..thanks
You missed an a – it’s regsvr32 wuaueng.dll
Worked for me
Thanks.
Thanks! Sorry about the Typo.
many thanks worked a treat ~~ with the ‘a’ lol
This worked Great. Many thanks!!!
Thanks fixed the problem for me too
regsvr32 wuaueng.dll
Lifesaver! I’ve tried about 10 proposed solutions with no results before i came across yours.
Don’t know if correcting the typo on the post is possible or not, almost got discouraged until i read comments! haha.
Thanks man!
