  • Born: Microsoft incorrectly signed the MSRT update that’s been bouncing around. It’s fixed now.

    News on that infuriating MSRT update bug. If you recall, the version of KB 890830 that arrived on Patch Tuesday was all over the map. As I said in Computerworld:

    There are hundreds of reports online of people who found that the MSRT installer threw an 800B0109 and wouldn’t install; or installed but then reinstalled on reboot; showed up multiple times in the Installed Updates list; didn’t show up in the Installed Updates list in spite of running; and several variations on those themes.

    I also said that the bad patch was fixed on Tuesday night – but, at least for some people, it wasn’t.

    Now comes word from Günter Born about the root cause of the problem:

    Microsoft made a mistake signing the update package in question… KB 890830 is no longer available via Windows Update… Microsoft has updated the package (in the Update Catalog) for Windows 7 and Server 2008/r2 and replaced the faulty certificate.

    He reports that the newly updated (but not yet pushed) version installs correctly. (Actually, I should say “runs correctly,” because the MSRT programs just run, they don’t install anything.)

    UPDATE: @Speccy has observed that the problem isn’t with the certificate, but with our old friend the SHA-2 signing problem with Win7 patches. Looks like he’s right. Read more here.
