I thought you might like to know how I fixed the dreaded 80070057 error when updates will not install. Your handling was not applicable to me because I am running Vista Home Basic SP1. I do not run a proxy server and the command gave an error to that effect when implemented. I have tried everything I researched on the internet through 20-30 web sites, maybe more, with no success. That included repair, installs, and re-installs.

What got me past it was I decided to do a clean re-install, that is, delete the partition and start again. I did not want windows to create a windows.old file, nothing, clean slate. I disconnected from the internet first. I selected not to download any updates and selected not to activate while online (didn’t activate the last 3 times I had it selected).

Once the installation had completed, I turned off UAC, rebooted, activated Vista [I had to do it by phone – straight through, no problems]. I then rebooted, and selected Windows Update from the Start menu. It downloaded the applicable updates.

I then cautiously selected 4 of the 17 updates, these were updates for Vista not security updates – and clicked on install with bated breath. The 4 updates installed wonderfully. I then rebooted, selected another group of updates for Vista, rebooted, more success. I then selected 4 security updates for Vista, rebooted, etc until all the updates had installed.

I have been hitting my head against the wall for 2 days. I hope this information can help others. I know how frustrating it can be looking for a fix that works, of course my fix may not help some, but it will help someone.
