Windows 7 updates keep installing, restarting and failing

Over the past week and a half, my Win 7 laptop has been trying to automatically install the same set of updates and failing over and over again. Sometimes the automatic install/restart cycle would happen in the middle of the night when the dumb thing was supposed to be sleeping. It would restart, say “Configuring Windows Updates”, then “Updates Failed, Reverting Changes” (or something like that).

The update history showed they mostly failed with error 80071A90. The help file on that error recommended running Windows Update manually after starting Windows in safe mode with networking, but the Windows Update service will not run in safe mode.

I found the solution in this Microsoft Answers article:

Assuming the updates-in-question include KB2515325, KB2492386, KB2506928, KB2512715 and/or KB982018 & all is well with your computer otherwise:

  1. Run a manual check for updates per
  2. Select (check) only KB2515325, KB2492386, KB2506928 and/or KB2512715 & install them; follow all prompts.
  3. Now run another manual check for updates, if necessary, and install KB982018 by itself; again, follow all prompts.
