Windows 10 will reach end of support on October 14, 2025. The current version, 22H2, will be the final version of Windows 10, and all editions will remain in support with monthly security update releases through that date. Existing LTSC releases will continue to receive updates beyond that date based on their specific lifecycles.

The reason for this is that Windows builds an identifier based on the hardware of the machine on which it is installed. When that identifier doesn't match, it throws a flag that says "Hey now ..." I think that you still get a couple of "honor system passes" before the installed OS enforces anything.
Once that gets enforced, you can call Microsoft Clearinghouse, "I upgraded my hardware," and they'll give you a new key to enter.
Whereas on Linux I recently upgraded the motherboard on my machine from a B350 to a B550, stripping it down to it's parts and rebuilding. Different network chip, audio chip, WiFi and Bluetooth, etc, etc. 6 SSDs plugged back in in a shuffled order.
Linux booted and worked first time, adjusting which drivers it used automatically, mounting all the drives in their original locations. Similar thing when I upgraded my GPU. Admittedly the old one was AMD, same as the new one, but there was about 4 or 5 generations between them. CPU upgrades too.
I've got a real machine of Theseus here. I think my case and my heatsink is all that's left from the original.
...oh...and the OS.
Windows will do the exact same thing. It'll even boot and run just fine, only telling you that Windows isn't activated. And you can get vendor support if you need it. I had a Windows system that started as XP and got upgraded and passed around among newer and newer hardware up to Windows 11 with nary a problem.
Apparently there is 2 types of Windows licences. The ones that are bound to the hardware and ones that aren't. If you bought a PC with preinstalled Windows, it's probably the first and you wont get any new keys.
I think you're right that OEM licenses are more strict on certain hardware changes, as in they wouldn't give you a pass on a single mainboard change - but you would still get a key from clearinghouse. As far as I'm aware, all retail and OEM keys are hardware bound. KMS/MAK are not.
