iirc the no windows 9 thing was actually because a lot of software ran a compatibility check like:
ifwindowsversion= “windows 9*” then open legacy mode
This worked for software written for newer windows like xp but still allowing a legacy mode on older windows versions like 95 and 98. Problem was this also put that same software running on windows 9 into legacy mode. So they called it windows 10 to sidestep the compatibility issues.
It's great to see to what lengths Microsoft goes to keep backwards compatibility. Compared to how a minor glibc update broke Linux apps without much warning. Without supporting legacy workflows I don't think Microsoft would've had the market share they have today.
