NOTES
  • devices joined to an Active Directory domain or Microsoft Entra (Azure AD) are not eligible for free 1-year ESU program offer
  • free ESU program is designed for personal PCs. A device that is joined to a domain is, by definition, a commercial device under central management, and therefore falls under the purview of the commercial ESU program and Vol Lic.
  • technically feasible to convert a specific local user account to a Microsoft account on a domain-joined node
    • Windows always allows users to sign in with their Microsoft account credentials
    • However, machine remains a member of the Active Directory domain, and the domain-level policies and management still apply. Microsoft's exclusion criteria for the consumer ESU program are based on the machine's domain-join status, not the type of user account logged in.
    • The catch-22 for this scenario: A domain-joined machine is typically managed by an organization's IT department. Even if a local user account exists on that machine, and even if you link that local account to a MSA, the underlying machine's status as a domain member and its connection to the corporate network make it ineligible for the consumer ESU. Attempting to use the consumer ESU on such a device would violate Microsoft's licensing terms and would not be supported. The enrollment wizard is designed to detect these commercial characteristics and will not offer the consumer ESU path.
