Just registered on these new forums to add my experience/ observations.
I've not seen it listed anywhere that alder lake is not supoorted on windows 10 yes it lacks thread director but I haven't seen much difference in my testing of Windows 10 and 11 on the latest 12th Gen Intel CPUs.
Also Precision Desktop Workstations such as the 3660 come with Windows 10 through downgrade rights I.e it comes with a Windows 11 license but Windows 10 pre installed and I would expect the same for laptops
Sure there may be some things Linux or Windows 11 does better but that doesn't help if your apps don't run on it or your business is standardised on Windows 10

Ive personally tested i7-12700k and i9-12900k desktop CPUs in Windows 10 and 11 with CAD, FEA, CFD and CPU based rendering applications and so far I'm inclined to believe the thread director doesn't make a huge ammount of difference performance was almost identical in my tests.
To me so far it in my testing it has seemed to be more about how the software supports alder lake. Many apps will need updates to fully utilise this new architecture or prevent it incorrectly using the e cores only. My results varied from fully utilising P and E cores with no tweaks needed while other apps launching secondary processes e.g. To mesh/ run the simulation running on E cores only. This was the same in both Win 10 and 11.
I managed to find some workaroundd so far high performance power plan/ plugging dual screens or raising the process priority to above normal in seemed to sort it but am feeding back to the developers.
The Workaround depended on the application and not all applications that used secondary processes had the issue or even the same issue!
Still early days in testing, I plan to test process lassoo also see of that can help.
But the main thing is we are talking enterprise level systems here I am 99.9% sure Windows 10 being offered on the majority if not all of latest generation of Precision laptops.
Some of the bigger companies I work with only just got off Windows 7 completely, big companies generally have little appetite for Windows 11 yet, I'd expect atleast a couple more years of downgrade licenses being preinstalled options from OEMs like Dell.

12th gen Intel Desktop CPUs are listed as supported.
Expect more news soon on Precision laptops that should put minds at rest 🙂
