license to deploy Windows 11 Enterprise LTSC with software assurance

Hi Alice,

Based on the descriptions you provided, both items appear to be per-device Windows Enterprise upgrade licenses with three years of Software Assurance: AAA-12379 is described as an Upgrade LSA, and KV3-00355 as an Open Value three-year Upgrade/SA pack. In principle, that is the licensing model used to access Windows Enterprise LTSC through Commercial Licensing. The exact entitlement for either part number should still be confirmed against your agreement and order.

Each target device must also have a qualifying Windows license installed. For per-device commercial upgrade licensing, Windows 10 or 11 Pro, Enterprise, or Pro for Workstations are qualifying editions; these upgrade licenses do not replace a full Windows license. Microsoft’s qualifying OS guidance and Product Terms list the applicable requirements.

Software Assurance includes new-version rights, including access to future LTSC releases. For a perpetual per-device Windows Enterprise license, Microsoft’s licensing guide says that after SA expires, the device may continue using the LTSC release current when coverage ended; that does not grant rights to a later LTSC release.

Also, the three-year SA term is separate from the product’s support lifecycle. Windows 11 Enterprise LTSC 2024 is supported through October 9, 2029. Microsoft Lifecycle If you mean Windows 11 IoT Enterprise LTSC, confirm that separately, since it is a different product with different use conditions.

Before deployment, ask your Microsoft licensing provider to confirm that each part number is valid for your specific agreement and region, the SA coverage dates, and that every target device has a qualifying OS. If you share which Windows edition is currently installed on the devices and whether the order is under MPSA or Open Value, the eligibility can be narrowed down further.
