The underlying mishmash of "Windows Technologies", whether thats win APIs, .NET, universal applications etc. isn't going away. Compatibility with many short lived standards of any given day is perversely, a requirement of Windows purchasers.
This means the UI can't really change very much, for fear of broken compatibility and business users saying get lost to the upgrade. Cue WinXP or Win7 hold-on for 5 years longer than MS wants anyone to do so.
Honestly; if they could release a copy without all of the fluff I'd consider going back to it. Will there still be 3 control panels; regedit, powershell and completely obscure routes to configuring stuff? (Yes, I know, systemD is also awful). But, yes, absolutely. Will there still be a Windows Store (yes, changing). Baked in advertising and a bottomless pit of telemetry? Yes.
And worst of all, the unreliable and vicious activation system that prevents legitimate re-installations without re-purchases. E.g. Replace a laptop motherboard; old windows install sees it as a new PC (semi-understandable why it thinks this). Go buy a license (Bugger that). Or rather more clumsily, replace a video card from one of another manufacturer and add an NVME, get told you have a new PC and go buy a new license. I don't really care that a license can be had for a fiver, legitimately, if you shop around. On a point of principle why should either of these scenarios force a repurchase?
While I miss certain applications and games I've spent quite a bit of cash on buying over the years; the PITA that Windows is just isn't worth the time sink that it represents. I have better things to do than burn a couple hours a month on administration of a PC.
In the meantime, I send nice emails to developers releasing titles that I'm interested in to ask where's the Linux version. Vulkan APIs mean there's not much excuse at this stage. We might be down in the 1-2% of desktop use, but build it and we will come (and buy stuff). I don't buy anything now that doesn't at least have a known, working compatibility bodge; and preferably a linux native release.
