Overview
Microsoft is formalizing the retirement of NTLM by publishing a staged phase-out plan and signaling that upcoming major Windows and Windows Server releases will ship with NTLM disabled by default. The combined reporting frames this as a security-driven migration toward Kerberos-based authentication, raising operational urgency for organizations with legacy NTLM dependencies.
