Don't software products tend to get slower, not faster, with each release? I think Windows 7 vs Vista was the only time I remember things getting better.

IOS 26 is also terrible (on battery especially). New OS releases always have a ton of new services in them that bog them down.

They do, but that's really not necessary. In the linked video you can see Windows 8.1 is pretty well optimized compared to the other Windows versions.

A lot of this slowdown is just developers getting complacent and getting used to the new hardware capabilities. Windows has a lot of low hanging optimization fruit laying around. It's just Microsoft doesn't really care about that: it doesn't fit the business model at all.
