I'm working on a Windows 7 Home Premium system (64-bit) with Service Pack 1 installed. Windows update is trying to install an update for KB2862330, but it's failing with error 800B0100. What's the trick to get this installed?

Some search engine research indicates this a general fault with Windows Update. I'm not sure what connection, if any, this problem has to the fix for KB2862330. The last Windows Update invocation installed a few updates, the one for KB2862330 was the last one in the queue and the only one to generate an error.

I tried the Windows Update Troubleshooter on Windows Update and the Background Intelligent Transfer Service. It identified a few problems for Windows Update. It fixed some the first time through and others on subsequent invocations.

The System Update Readiness Tool wouldn't install. The only error message was a generic 'Could not be installed'. There was nothing useful in C:\Windows\logs\CBS\CheckSUR.log, either:

Multiple runs of the Windows Update Troubleshooter on Windows Update and the Background Intelligent Transfer Service got the system to the point where the update installed.

After the update installed, I tried installing the System Update Readiness tool again. It took an hour or so, but succeeded. Still nothing exciting in C:\Windows\Logs\CBS\CheckSUR.log:

I suppose based on the difference between the two log files, it could be inferred that in the earlier SUR invocation, there was some sort of problem with the Manifests or Catalogs. Assuming all the output was properly flushed to the logfile before the failure.
