    Win 10 Defender definition updates.


    My Win 10 has become unable to find any new Defender virus definitions since 11/10/2020. I tried to trigger the update but it says my Windows is up to date. I have gone to the latest update, downloaded it and ran the updates. I runs and when finished, I check, and the previous update is still listed. I have tried the fix using a command prompt, and run as administrator. No change. Can someone tell me what is wrong with this thing without having me jump through endless hoops? I'd really appreciate it. Thanks.
