Windows Update Stalled on Windows 7

Windows Update stalls on Windows 7

• SP1 is installed
• Will update Security Essentials definitions
  a scan found no problems
  computer has never had a virus that I know of
• The hard drive had not been used for a couple years
  It did install 4 old update that had been downloaded but not yet installed
  It is a sister to an identical computer that had a failed mother board
  The hard drive failed so I just took the hard drive from the bad mother board
  But that does not seem to be a problem - it Activated and everything else works fine.
• Malware Bytes found no problems
• Installed the KB947821 / Readiness tool for Windows 7 and it ran and said OK
• The update service and Windows Update just stick on "Searching for updates"
  I have let them run for 2 days each
  CPU 50%
• KB3172605 / Diagnostics finds a generic 800700 error that it cannot fix
  It will find a previous a failed update and fix that
• Shut down the service reboot and try KB3020369 April 2015 rollup
  searching for updates for over 12 hours - I will let it run 2 days

What else can I try here?
