Earlier quoted context omitted.
You can solve this problem with branding. Have a "Windows OS Bleeding Edge" brand that changes regularly. Have "Windows OS LTS" brand that changes less often.
They have tried exactly that with Windows 10 LTSC. And killed it off quite qucikly.
They really didn't.
Full disclosure: I installed Windows 10 Enterprise LTSC 2021 on a brand new laptop earlier today :)
For this specific device, my wish is a Windows-compatible OS that's going to shut up and stay out of the way, and it seems the LTSC variant of Win10 is the closest Microsoft are willing to provide at the moment.
That LTSC doesn't come with Edge, Cortana or the Windows Store, well that's just the icing on the cake.
