An error code shows up 0x80070652

I had similar problems and the following is what I eventually did to get things up and running properly.  But, as needed, I must say: "I cannot be held responsible for any repairs, suggestions, and any other do-it-yourself fixes.  I am only saying this worked on about 21 computers that had this problem.  You are on your own after this.

FOR Windows XP and Windows 7 only.  I have not tried this on Windows 8 yet

The update files may have become corrupted.

1.  Log in with administrator privileges

2. Open a command (cmd.exe) window

3.  Type or copy and paste in the cmd screen:

       net stop wuauserv 

       net stop bits

4.  Open Windows explorer and drill down to C:\windows\softwaredistribution

5.  Right click on the softwaredistribution folder and rename it to softwaredistributionOLD

6.  Find windowsupdate.log (C:\Window) and right click on rename this file WindowsUpdate_OLD.log

7.  Go back to the command window and type or cut and paste:

      net start wuauserv

      net start bits (this will rebuild the Windows file and folder you just renamed)

8.  Finally, type or cut and paste:

      wuauclt.exe /resetauthorization /detectnow

      wuauclt.exe /reportnow /detectnow

If the above works for you, as it did for me, then hurray!  If not then repeat step 3, reverse the renaming, and repeat step 7.  Note - you will have to delete  the new softwaredistribution before renaming the OLD folder back to SoftwareDistribution.

OR

Copy the following to a Note Pad and name it WindowsUpdateFix.bat and run that file:

ECHO off

Again, you are on your own and I will not be held responsible for any problems after this.  This works for me and should work for you

The same error code 0x80070652 appeared whe I tried to update Win 8 to 8.1. I also rebooted but no use.

Thank you. I rebooted my PC and it worked.!
