Windows update error 800B0100 [duplicate]
Windows Update on one of our Windows Server 2008 machine stopped working. Whenever I click on Install Updates, it fails with the 800B0100 error. I did some investigation and noticed that it’s not an uncommon error. I found a number of discussions threads reporting the same error on Windows Vista. However, I could not find any leading to a useful conclusion. I also found a Microsoft KB article (KB 956702), but it’s not very revealing. It recommends to run System Update Readiness Tool. When I ran it, it looked like a long update, and when it finished, it did not say anything. So I assumed it did whatever it wanted to do. I found some logs which the tool supposedly produced, but there were full of gibberish to me. Also, the tool did not guarantee to fix all problems.
