windows update Windows Update error code 666 on Windows 8.1

[svenwlive]

I was doing updates on my pc and i got a very suspicious error code. It was just saying 666 as the error code. I'm very confused on why is it that specific number. After i saw the error code i just came here to ask about it.

 

 

 

 

Please help me with this error code.

Code 666. I think you might need a exorcist.

I found an article about two error codes: 666 and 667. It was written on Microsoft's official forum.

 

 

 

Should i use that command?

That's often a good command to run because it replaces any files which fail Microsoft's integrity check. I think the Xircal person made a typo.

 

DISM /Online /Cleanup-image /Restorehealth

 

That said, this appears to be a .NET 4.5 issue rather than one strictly caused by the Windows Update process. This in my experience is a pain to fix because Microsoft doesn't make repairing the 4.5 framework simple or straightforward. Notably, DISM doesn't reliably repair .NET problems, regardless of version (2.0, 3.0, etc). Hence, I suggest running the following tool to verify and repair .NET updates independent of Windows Update:

If the problem persists, you can use the same tool to repair the entire Windows Update catalog, though I believe that will be unnecessary. I have used this technique to repair a damaged update catalog many times. Microsoft's update catalog is otherwise pretty darn inscrutable, so I've not run across any other software which can fix it, not even from Microsoft themselves.
