Hello Alice,

Thank you for posting question on Microsoft Windows Forum!

The MPSA license AAA-12379 (Windows ENTpD Dev UpLSA) is a general Windows Enterprise upgrade license with Software Assurance for a single device. This SKU is not the same as an LTSC-specific license. While Software Assurance (SA) generally provides New Version Rights to upgrade to the latest version of the licensed product, Microsoft's licensing structure treats Windows Enterprise LTSC as a distinct product line that is not automatically covered by the standard Windows Enterprise upgrade + SA license.

To deploy Windows 11 Enterprise LTSC with proper licensing, you would typically need to acquire the dedicated LTSC upgrade license (such as AAA-12384) for each device, on top of the qualifying underlying OS license. The AAA-12379 license, on its own, does not grant the right to install and use the LTSC edition.

Please note: Licensing terms can evolve, and program-specific rules may have nuances. it is always recommended to verify with your Microsoft licensing partner or the Microsoft Volume Licensing Service Center using your agreement number.

Thank you Chen!

I have a few more questions,

Does Win Enterprise Device ALng Upgrade SA OLV D 3Y Aq Y1 Ent (KV3-00355) provide eligibility to deploy Windows 11 Enterprise LTSC with software assurance?
If under MPSA, should I use Win 11 Ent LTSC Dev UpLic (AAS-87244) plus Windows ENTpD Dev UpLSA (AAA-12379) to deploy Windows 11 Enterprise LTSC with 3 years software assurance?

Many thanks!

Hi Alice,

Thank you for the extra information!

Windows Enterprise Device ALng Upgrade SA OLV D 3Y Aq Y1 Ent (KV3-00355) which is an appropriate licensing option for deploying Windows 11 Enterprise LTSC with Software Assurance. The important distinction here is that this is a Windows Enterprise per-device Upgrade + Software Assurance package, not an LTSC-exclusive license. Windows Enterprise per-device Software Assurance provides New Version Rights, including access to future Windows Enterprise LTSC releases during active SA coverage, access to Windows Enterprise LTSC as part of the Enterprise licensing benefits and perpetual use rights for the LTSC version current when SA expires, provided the device has the underlying perpetual Windows Enterprise per-device license. For more information https://www.microsoft.com/en-us/licensing/licensing-programs/open-license

Regarding the second query of AAS-87244 + AAA-12379. Basically, it is not recommended to combine these two SKUs for the same device. Doing so results in a redundant and incorrect licensing structure. For AAS-87244 (Win 11 Ent LTSC Dev UpLic) which is a Perpetual License-Only (L) SKU. It grants a permanent upgrade license to run Windows 11 Enterprise LTSC on the device, but it does not include Software Assurance (SA). On the other hand, for AAA-12379 (Windows ENTpD Dev UpLSA) which is an Upgrade License and Software Assurance (UpLSA) bundle. It inherently includes both the underlying upgrade license and 3 years of Software Assurance bundled into a single maintenance/subscription stream. Hence, purchasing both is generally unnecessary for the objective you described. AAA-12379 already provides the underlying Windows Enterprise license and SA benefits that include LTSC. Adding AAS-87244 does not simply convert AAA-12379 into an LTSC-specific SA package.
