Mesa 3 moving to Windows 10 IoT Enterprise

30 Jun 2022

26 October 2022 Update: The Windows 10 IoT Enterprise license begins around serial number 338818. If the unit was produced between 18–31 October 2022, it could be licensed as either Pro or IoT. To find out which license your device has, go to Check Product Status.

This is a notice that Microsoft has set a cutoff date for manufacturers where they can no longer sell devices with Windows 10 Professional OS licenses installed.

Due to Microsoft's hardware restrictions of Windows 11 Professional, Juniper Systems cannot provide it as the operating system for the Mesa 3 Windows device. Juniper Systems has identified Windows 10 IoT Enterprise LTSC 2021 as an alternative operating system that will provide customers with the same features as Windows 10 Professional (Windows 10 IoT LTSC Enterprise 2021 is equivalent to the 21H2 release of Windows 10 Professional).

Juniper Systems is offering a testing period for Windows 10 IoT Enterprise.
