Is it NTLMv1 that will be deprecated later this year or NTLMv2 also? It's not quite clear.

AWTG - (From Steve_Syfuhs) - NTLMv1 has already been deprecated for more than a decade. It was deprecated when we introduced Credential Guard in Windows 10. As such, we're talking NTLMv2.

Hi Heather_Poulsen sorry I meant 'retired'. As per KB ID: 5066470
NTLMv1 will be blocked in Oct'26. I want to confirm that's still the plan or is v2 also set to be disabled later this year?- mariam_gewidaMar 03, 2026

Our plan is for NTLMv2 to be disabled by default in the next major release of server and client: Advancing Windows security: Disabling NTLM by default - Windows IT Pro Blog
