Windows Update .NET 4.0 patches fail with "800B010B Generic Trust failure"

    Question

  • I have been back and forth across the forums and other places looking for a solution to the "Generic Trust Failure" (800B010B) error when running in the following KBs for .NET 4.0 on Windows Server 2008 R2 (x64):

    KB2487367, KB2604121, KB2656351, KB2729449, KB2736428, KB2737019, KB2742595, KB2789642, KB2804572

    These all fail with the same error code - 800B010B - whether they run as a group via Windows Update or ran one at a time.  Microsoft .NET 4.0 will uninstall and install with no trouble.

    Anything new on this one?  There seems to be at least three different threads chasing a different theme.

    Best...

  • That 800B010B error for Windows Updates could be related to a corrupted Downloads cache on the local computer. 1. Turn off Windows Updates and disable the 'Windows Update' service. 2. Delete everything under the C:\Windows\SoftwareDistribution\Download and C:\Windows\SoftwareDistribution\DataStore folders 3. Restart the computer. 4. Log back in and enable Windows Updates and it should successfully download and install the failed updates. If all else fails, try to install the update manually. Hope this helps.
