Wey-ull, Pil-Grum! It was a lot of trouble beginning 1st of July and sorting out three perfectly good DIY-Built desktop PCs, the last one commissioned in spring 2022 from 2017 otherwise "new" parts. My daily driver has the ESU under Windows 10. The other two got Windows 11 installed after adding TPM2.0 modules and making a single registry hack -- easily upgraded to 25H2.
And I'm building a new system from parts released around 2022. I'm starting on that project now because I need a project to fill my time and avoid the TV news. Just got notice from my Amazon account that an SK Hynix P41 NVME has arrived so I'll check my mailbox.
So I've "done it" three ways. I got the ESU. I successfully installed and updated Windows 11. And I even got to test an installation "in-place" of Win 10 IoT Enterprise 2021 LTSC -- which would've continued running fine and indefinitely had I not replaced it on the same hardware with Win 11 Pro.
Anyone else left behind or slow-to-adopt just needs to be careful while following a proven solution to the Win 10 end of support.
