I finally fixed the update problem with an Acer Aspire 5315 Laptop.
I installed KB2993651 for win 7 32 bit.
I then got update error 80244019
I then looked that up & installed KB 971058 -
it went to 100% CPU but less than 100% after 5 minutes.
It then was able to get updates.
It downloaded 187 updates to 100% completion.
It started installing 187 updates & got to 30 % then rebooted & was still going at 32% of updates when I left my friends place.
I phoned her & it seems ok.
I'll have to check next time I'm there that it's all done.
Moral of the story - don't give up - keep trying.
cheers
Bobby
