They need to step back and get the basics sorted again. People are not enthused with their new features (hence the win10/11 install figures).
Funny you should express that sentiment just now.
I was just enjoying being brought back to when life was simpler and the slow post-2000 rot of UI design hadn't kicked in by a thin client I recently finished converting into a "Windows XP pretending to be Windows 98SE" box (it had no drivers for actual 98SE) and musing on something I wrote earlier about how UI designers should be required to read 90s HIGs (
1,
2) and spend some time using Windows 98SE and WinAMP and the like to get some perspective for how little of value or consequence they've added to desktop UIs in 20 years of trying and how much they've ruined in this rush to rewrite everything on web-tech and try to force convergence with mobile design rooted in very different hardware limitations and interaction modalities.
(Granted, I did also then free associate to a memory of the Freeman's Mind version of Gordon Freeman shouting "No, not like that! Start over!" as he returns fire on soldiers trying to kill him, but that's just me. My brain likes to free-associate things that make me grin.)
