Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Mark Henderson Jun 26 '15 at 3:59

Here is what I did and it fixed it - Thanks to Mary.

Create a batch file with the following and run it from a command prompt.

regsvr32 MSXML3.dll /s  
net stop wuauserv  
cd /d %windir%\SoftwareDistribution  
rd /s /q DataStore  
net start wuauserv   
regsvr32 softpub.dll   
regsvr32 mssip32.dll  
  • Go to services and stop the Windows Update service
  • Go to the Windows directory (default is c:\Windows) and rename the "SoftwareDistribution" folder to "SoftwareDistribution.old"
  • Go to services and start the Windows Update service
