The only way you're doing that is by using workarounds that Microsoft knowingly left in place, to allow people who are somewhat knowledgeable to still use Windows rather than switching to Linux if they absolutely refused to upgrade their Windows hardware, while eliminating the requirement for them to provide any real support and letting them ignore any compatibility issues that might later arise. With 24H2, that workaround may become completely impossible for processors that it currently works on as there is an underlying CPU feature requirement for the OS that isn't available at all in older CPUs and therefore the basic OS code may not run (SSE4). (A 10 year old CPU has it, but there are some that can run W11 using the workaround right now which won't be able to run 24H2.) They have decided that supporting older code paths is no longer of enough benefit versus implementing new code and functionality in the OS (just like Linux is dropping support for the 486).
If they decide that an NPU and the AI features in Windows 12 or Windows 14 (they'll skip 13 or change the numbering scheme entirely) are a "core requirement" the way SSE4 is now, then at some point they'll probably only officially support processors with NPUs that are higher performance than the current newest ones (which on x86 barely meet the minimum specs MS has set) so probably 2025 and up, and the equivalent of the W11 workaround will allow you to install it on 2024 processors like Meteor Lake and Lunar Lake, or perhaps if your GPU can run AI, but it won't be "supported", and it might not install at all, period, on anything older.
