Anyone else notice that on all computers MS defender updates gave error message and failed to install? Haven’t noticed this before. Maybe my pipelines aren’t clean and clear!

Yes, indeed, I had this issue on both of my machines this morning. That was very weird and a bit scary. First thing that came to mind : Virus or Malware. Troubleshooting Updates didn't seem to be able to fix the issue. I had to run . bat file for resetting Windows Update to finally see some relief.

Also, 21376.1 installed easy-peasy:

I skipped the last two updates, this one was smooth.

Updated without any problem

smooth update but got the end of service msg

Downloading

I dont know if its a problem yet but now down in the lower right corner Im getting a message that say my version of windows 10 has reached the end of service, and to download a newer version of win 10 to stay supported this just showed up

I didn't get it, but if you go some posts behind you'll see you are not the only one. Restarting the machine seems to help in fixing the issue (not sure though).
