I'm unable to run windows update and keep getting error code 800706F7.

Have done the following:
  1. Ran sfc /scannow
  2. Ran Windows readiness tool (KB 947821).
  3. Stopped wuauserv service and renamed softwaredistribution, restarted service.
  4. Ran SFCFix tool (attached log file).

Any help will be appreciated.

thanks,

How do I upload a zip file containing my CBS folder of the machine. I thought there were some special instructions and I can't find them
 
Hello PhilA,

The instructions have been removed for the upload.

Export CBS folder

  1. Click the Start button
    StartButton_16x16.gif
    then click Computer.
  2. Double-click on the C: drive, under the Hard Disk Drives category, and then scroll down to, and double click on the Windows folder.
  3. Find and double click on the Logs folder.
  4. Right-click on the CBS folder, and select Copy.
  5. Go back to your Desktop, right-click on it, and select Paste. You should now see a copy of the CBS folder appear on your Desktop called CBS.
  6. Right-click on this new folder, and navigate through Send to, and select Compressed (zipped) folder.
  7. A new file, also called CBS (CBS.zip), but this time with a different icon, will be created.
  8. Attach this to your next post please.
Please Note:: if the file is too big to upload to you next post please upload via Dropbox or One Drive
 
One other thing you must do and that is, you should change your window update setting to: download updates but let me choose whether to download. You want to do this because Microsoft will download this problem update again if your window updates setting is on automatic. I don't know why Microsoft haven't addressed this problem yet.

This problem is caused by Microsoft update KB3004394. Go to view all updates and find this update and uninstall it. That will solve the problem.

Thank you, Jayden, this worked like a charm for me, I had 7 optional updates which were linked among them (one needing the other) and 3 of them had this issue caused by KB3004394. Removing the aforementioned update fixed the problem. Do you know why a Root Certificate update would cause such a severe issue? I'm a bit worried that I might have removed a critical component from my workstation (I had this issue at work).

Best regards,
Bogdan
 
Thank you very much! After removing the update, all the others installed correctly.

You can consider this issue closed.
 
This comment from the VirtualBox ticket may help illuminate what's going on:From what I can tell, the KB3004394 update does not install a catalog file on 64-bit windows 7. It does on Windows 8.1 (C:\Windows\system32\CatRoot\{F750E6C3-38EE-11D1-85E5-00C04FC295EE}\Package_1_for_KB3004394~31bf3856ad364e35~amd646.3.1.0.cat), so VBox works fine there.
The result of the missing .cat file is that VBox (nor SysInternal's SigCheck.exe for that matter) is not able to verify the authenticity of c:\windows\system32\crypt32.dll and wintrust.dll. If we cannot find any valid signature for the files, we have to assume that they have been tampered with and are forced to abort application loading. These two dlls are important for validating other components, so there is absolutely no way we can ignore this.Until Microsoft fixes the KB3004394 update on Windows 7, the only solution is to revert/uninstall it.
