    0x80070643 Error when updating Windows Defender

    Have had this error for a couple days now. Tried regular checks to verify system components and online image and windows update service diagnostics, cleaned up SoftwareDistribution, turned off non-Microsoft auto starting services, - all to no avail.

    Also, ran netfxsetupverifier, which gave me the only error - aspnet.mof missing, which I presume is OK.

    Any suggestions how to resolve this?

    I was able to resolve this by MANUALLY updating the definition set. Is this the way to go in the future should the problem persist?

    The problem still persists. The Windows Defender does not update via Windows Update, but, somehow. the definitions keep up to date, from time to time. Any idea how to fix this?

    The MpSigStub.log contains the following record pertaining to the error:

    Any idea how to proceed forward? Cleaning up SoftwareDistribution and deleting the temporary folder indicated above does allow to update Windows Defender flawlessly, but just once. The error keeps coming back the next day.

    Update: Did exactly as suggested here and let it stay that way for a while. Miracles! The issue has been gone for good!
