Hello.

I am currently using Windows 11 IoT Enterprise 2024 LTSC, but I would like to change it to Windows 11 Enterprise LTSC.

However, I am not sure which license I need to purchase.

When I checked with Microsoft partners in Korea, they told me that I must first have a Windows 11 Pro license before I can purchase Windows 11 Enterprise LTSC.

Could you please advise me on the correct licensing option and the most appropriate way to make this transition?

Thank you in advance for your support.

Best regards,

Windows 11 Enterprise LTSC is considered an upgrade license, not a full standalone retail operating system license. That is why the Microsoft partners told you that you first need a qualifying base license such as Windows 11 Pro. In normal commercial licensing, Enterprise editions are layered on top of Pro licensing through Volume Licensing or Microsoft 365 subscriptions.

Windows 11 IoT Enterprise LTSC is licensed differently from standard Windows Enterprise LTSC. IoT Enterprise is usually tied to OEM or embedded-device licensing and is intended for specialized hardware devices, kiosks, industrial systems, POS systems, and appliances. Even though the operating system looks very similar, the licensing channel is separate from standard Enterprise licensing.

If your device already came with a valid Windows 11 Pro OEM license in firmware, you may only need to purchase a Windows Enterprise subscription or Volume License activation entitlement. In that case, you could move from IoT Enterprise to standard Enterprise LTSC by reinstalling the correct LTSC edition and activating it with the proper Enterprise LTSC key obtained through Volume Licensing.

If the device does not have a qualifying Windows Pro license, then the partners are correct - you need to acquire a Windows Pro license first before obtaining Windows Enterprise LTSC rights. Microsoft typically sells Enterprise LTSC through Volume Licensing programs such as Open Value, CSP, or Enterprise Agreements rather than consumer retail channels.

You should be able to use the following procedure:

  1. Confirm whether your hardware already has an embedded Windows Pro OEM license.
  2. Purchase Windows Enterprise LTSC through a Microsoft Volume Licensing partner or CSP provider.
  3. Perform a clean installation of Windows 11 Enterprise LTSC media.
  4. Activate using the Enterprise LTSC MAK/KMS key or subscription entitlement.

In addition, keep in mind that Windows 11 Enterprise LTSC is intended for specialized or fixed-purpose business systems. For general office PCs, you likely be better off using standard Windows 11 Enterprise rather than LTSC because LTSC receives fewer feature updates and has limited support for some modern Microsoft apps and services.
