Installing Windows Vista SP1 and Error 0x800F0826

I’ve installed Windows Vista SP1 today. Unfortunately, the two first tries were unsuccessful, due to a message received after a few restarts (right after a "Configure Updates – stage 3 completed 100%" message and allowing log on after that) indicating an obscure error with this number: 0x800F0826.

After searching on the Web for the issue there was nothing that could be used.

I contacted Microsoft Support on their chat line (it’s free), and… surprise… they actually DID help me! The trick was to start 2 services in Control Panel Services, and set them to Automatic: Windows Event Collector and Windows Module Installer. After that SP1 has successfully installed.

I hope it helped other people like those from these forums or blog entries:

    Good post, I had a similar experience ( with Vista, but ran into a couple of other issues before it uncovered the problems with the services not starting up. By chance, was your machine a Dell computer as well?

  2. Sorin says:

    No, my machine was an Acer notebook, so I think this is not brand-related (or may be related to more than 1 brand otherwise).

    Over six years later, and this post is still helpful. I had to reset my OS on my years-old laptop, but I didn’t realize all the things I’d be losing. I bought a new printer (for a very important document) but couldn’t even install it without a service pack. I was near insanity after so much trouble just getting SP1, but this one little change did the trick and it means so much.
