Anyway Windows will remain an x86 affair only for the foreseeable future.
It's so obvious, it's not even funny.
Go to your local PC-using neighbor, try to sell him an ARM Windows PC and see what happens.
Lol and we'll see as Microsoft themselves woth their DevKit last spring was fully and only ARM based. The legacy code in X86-64 is very old and mostly due to Microsoft, IBM mainframe emulation ans similar from decades old use.
Most developers don't even write new code for replacement, and the latest windows os (8, 10, 11), would have incompatibility for the ancient legacy code bring maintained in Intel's chips.
Trust me new software and ending support from vendors will increase significantly, to the point where old servers will be required for maintenance of legacy systems. I'd presume Nuclear power plants have requirements for ongoing business of such legacy.
Oh yeah and NVidia has already announced along with AMD their competing ARM desktop n laptop chips are coming in 1.5yrs! Nvidia already has some experience foe mobile ARM chips as well as IoT for cars.
If I can show any PC gaming, architecture, artist or business official that a shipping product outperforms their current setup, has 90-100% software compatibility (no need for x86 legacy chip code for these use cases btw), ans can save them 60% on their monthly and yearly hydro bill alone?!
Trust me they'd be ripping my tie off to sell them!!
You'll see and soon too.
