| (in my particular case, at least), I never figured out exactly what the exact problem and solution were.
What I did was to stop all unnecessary services and rerun the update. Then it worked. Apparently, one of the active, running services was interfering with the update. Which one, exactly, I don't know. Why it doesn't happen all the time when the offending service(s) are running, I don't know. Which specific service(s) were the ones causing the problem, I don't know.
Of course, you have to leave the services running to maintain network connections and to access Windows updates, but you can temporarily stop stuff like cryptographic services, secondary logon, anything that you don't need just to connect and install the updates. |
