Cannot Update Microsoft Defender.

[Guest]

Since the day I installed Microsoft Defender, I haven't been able to
updated... not even once and Windows Anti-Spyware was my only AntiSpyware
program. I keep getting this error message:

"Windows Defender was unable to complete the update:
0xc8000202"

If you go to Windows Update, are you offered updates?

Are you on a managed corporate network?

Have you tried the steps listed in this KB article?
