Unable to perform Windows update with error code 800B0001

Original Title: Windows Update says it has to update Windows Update to proceed but it fails with error 800B0001.  I have a Windows 7 Professional x64 system


Windows Update says it can not scan for additional updates until a newer version of Windows Update is installed.  When I click the button to install the newer version, it immeidately fails with error code 800B0001.  Windows Update worked correctly up until this afternoon when it first failed.
