Please Note - Defender cabs (x64, arm64 and x86) will continue to be updated until end of the Windows 10 ESU programme.

Users that are running both Enterprise editions of LTSC 2021, defender cabs will continue to be made for x64 until end of support of both SKU's. As for x86, I will continue making cabs until end of support date of the LTSC Enterprise 2021 version. Which is on January 12th, 2027!

I missed something. I apologize for that. I thought Defender should be uninstalled, not updated. Would you please help me to understand. Thank you.

User choice, some people prefer to have a Antivirus installed and kept up to date. So that's the reason why I update these defender cabs once a week cause I like to help others, and if it keeps other people protected from online threats like malware, ransomware, etc then I feel better knowing that.

Of course you don't have to have a antivirus software installed or one that comes built-in, as I said it's down to the user to decide that.
