I don't think you can update any 10-year-old windows computer to the latest version of windows (11) with all security patches via official microsoft channels.
(Also, lol @ "via official Apple channels", you're aware Open Core Legacy Patcher is a thing and have hedged against people mentioning it.)
Not 10 years old, but I have a 2017 laptop that updated to Windows 11 just fine. It's somewhat slow though and I enjoy the dual-booted Linux on it more.
You can easily patch a config file in Windows and install it on old hardware and get regular updates as usual.
OCLP is more complicated and limited as it's not a "some manifest config limitation", but actual support parts of OS being removed, so they have a big lag and a bunch of issues, and limit your updates
So yeah, no contest comparision between Mac and Win
I consider the WinBootMate thing suggested in your second link to be similar to OCLP. Third party solutions to enable installing on hardware the vendor doesn't want you installing it on.
Did you even notice that the link marked as solution is a third party software vendor?????? They charge money for that solution.
Microsoft does let's you bypass it (Regardless of them putting up a disclaimer) so the example stands, you can do it hardware and software wise without losing updates or security*
Microsoft removed the mandatory requirement, so now instead of refusing to install it just gives a disclaimer that it's "unsupported" as per the linked page
So you can install Vanilla Windows 11, no third party, on decade old hardware without losing anything other than performance (And an annoying disclaimer)
(Also, lol @ "via official Apple channels", you're aware Open Core Legacy Patcher is a thing and have hedged against people mentioning it.)
What are you comparing to?
