Windows 10 IoT licenc

Szerintem csak ha fizetsz érte. :)

To update Windows 10 IoT Enterprise 2019 LTSC to Windows 10 Enterprise IoT 2021 LTSC it's a paid upgrade sadly.

You need to contact your terminal manufacturer, as it's them that can sell you the upgrade. The way it work it's the OEM that will allow your BIOS key of Windows 10 for the new version when it's sold.

If you got the license via an agreement to build your terminal then it mean you have sadly to repurchase the new version with new keys. I don't know if the revendor can give a rebate in such case.

Csak a 19-est. Próbáltam, be sem aktiválódott a 2021 ugyanazzal a kóddal amit a 19-eshez adtak a géppel.
