Windows 7 Update fails with error code C000000D - Windows Update encountered an unknown error

I tried running windows update from the action center today and now get this error message.   Last successful update was a couple of weeks ago. Rebooting the computer makes no difference. I have run the windows update troubleshooter found on the update error window available under the "Get help with this error" link and it says that it fixed two problems (Service registration is missing or corrupt - Fixed,  Problems installing recent updates - Fixed) but windows update still refuses to run.  The troubleshooter did return one puzzling piece of information; it said  "Windows Version: 6.1, Architecture: amd64" when in fact Windows, when asked, will say that it is a "Intel Core i7-2600k" (3.4GHz quad core sandy bridge to be specific).

Are there any suggestions how I might troubleshoot or fix the update failure?

In the WUDiagTempFolder\windowsupdate.log file I did find this section that referred to this error:

It looks like a file is not trusted by the machine.  How might this be fixed?

In the end I just rolled the system back to a restore point that corresponded with the last successful Microsoft Update and that fixed whatever was causing the problem. New updates load fine now.

    Your problem is different to the one Aisha has.

    Please provide a copy of your System Information file. Type System Information in the Search Box above the start Button and press the ENTER key (alternative is Select Start, All Programs, Accessories, System Tools, System Information). Select File, Export and give the file a name noting where it is located. Do not place the cursor within the body of the report before exporting the file. The system creates a new System Information file each time system information is accessed. You need to allow a minute or two for the file to be fully populated before exporting a copy. Please upload to your OneDrive (formerly Sky Drive), share with everyone and post a link here. Reports in normal mode preferred. Please say if the report has been obtained in safe mode.

    Please upload and share with everyone fresh copies of your System and Application logs from your Event Viewer to your One Drive (formerly Sky Drive) and post a link here. You can remove the earlier copies of the logs from your OneDrive.

    To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window expand Windows Logs and select System. Place the cursor on System, select Action from the Menu and Save All Events as (the default evtx file type) and give the file a name. Do the same for the Applications log. Do not provide filtered files. Do not place the cursor in the list of reports before selecting Action from the menu. Do not clear logs whilst you have a continuing problem.

    For help with OneDrive see paragraph 9.3:

    General notes on Event Viewer

    Please note you are providing copies of three files not two!

    You did not provide a copy of your System Information file. Looking at the two Event Viewer logs I cannot see any evidence of the problem being complained about in this thread in the last couple of days.. There are suggestions on the 28 August that the system has been updating Windows Update so this may have resolved your problem.

    Is your problem still present on the computer?
