They don't care if Windows is good or not because they don't make any money on it. Today, the only purpose of Windows OS is to advertise (or force) other more profitable Microsoft products as cheaply as possible.
Windows & Devices is still a $14ish Billion/year or so business for Microsoft. I know that doesn’t seem like a lot, but that’s a lot of money they’re apparently not making which would make their most recent 10K filing with the SEC a lie. It’s apparently enough money they’re not making that they keep screwing with Windows in unproductive ways that make their Windows customers resent them every time they release an update.
