It's actually kinda annoying once I started paying attention, as many software vendors just detect "Windows" and give you a x86/x64 installer, even when the company offers a ARM64 build that would presumably be faster or be more energy efficient. I installed a bunch of stuff that were Intel binaries without even knowing that I wasn't running native. But I haven't noticed any performance issues, and yeah everything just works.
In 2018 that lockdown situation morphed into "S Mode" which you can turn off in the control panel. The only trick is that you can't turn it back on. It's just that the ecosystem isn't there, both in terms of developers and performant devices.
Hopefully today's announcement is a turning point for that but atm windows on ARM is about on the same tier as a pre-carplay infotainment system.
