Microsoft in particular seems hellbent on putting touchscreens in everything. They REALLY want to make it happen but seemingly no one is having it. There's ONE person I know who owns a touchscreen laptop and genuinely touches its screen on purpose.
On your scrolling complaint — well, there's this desktop-specific thing that OP doesn't mention but that becomes very apparent once you start looking for it in old-school desktop UIs. Controls never, ever scroll. Only content does. If controls don't fit into a window, you don't make it scrollable — you split it into tabs or you put the extra controls into a separate window that opens via a button. This appears to be universal at least for Windows and macOS.
