Windows XP 64 bit edition was Microsofts peak, everything has been downhill from there. Microsoft Research (a child company of Microsoft proper) does some really cool stuff. Everything interesting/good to come out of MS in the last couple decades started there, and then the main Microsoft company got ahold of it and inevitably cocked it up.
For a brief period of time I was hopeful that MS had turned over a new leaf when they started to opensource their dev software like VS Code and typescript, but that’s always been a bait and switch. They’re handing carrots out to developers while simultaneously beating their normal customers with sticks.
