    Windows 7 Update Error 800B0100

    Windows 7 home premium 64bit w/ SP1 applied.
    Updates failing are security updates kb3212646,2871997,2984972,3003743,3011780,3060716,3071756,3126587, and MSRT kb890830
    SFC scan found no problems, but I've attached the CBS log anyhow.
    The error insists the Cryptographic Service has issues, but services.msc shows that it and all of its dependencies are automatic and started.
    chkdsk found no problems.
    memcheck found no problems.
    I've run the Update Readiness Tool.
    I've run MicrosoftFixit50362
    I've tried disabling windows firewall.
    There is no security software installed except Security Essentials (if that qualifies )
    I've completely reset and reinstalled windows update agent with the following script:
    net stop bits
    net stop wuauserv
    net stop appidsvc
    net stop cryptsvc
    Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\qmgr*.dat"

    I've seen a few other users post about this error and get a custom-made zip package, such as here: Windows Update Error code 800B0100 - Unknown Error

    How is that package generated? I'd like to know for the future.

    This fixed the System Update Readiness log errors: Advanced guidelines for diagnosing and fixing servicing corruption

    That's how the Pack.zip file from the other thread I mentioned was crafted.

    Running an update right now, we'll see if it works...

    edit: My updates have now successfully been applied.
