I'm a sysadmin. I professionally support about 30 Windows users plus a couple hundred classroom computers, and personally my family's PCs. And you are full of shit.

Starting December of last year, every time Microsoft released a cumulative update, I'd get an influx of OS-related issues, including:

• Microsoft Store breaking installed applications
• Broken HDMI, audio, and wireless device drivers, one of which was only fixed after a wipe and reinstall
• Bitlocker failures that couldn't be decrypted with the key from the user's Microsoft account
• Two occurences of a wiped EFI partition
• One occurence of a completely broken installation
• One occurence of a corrupted motherboard firmware

You can call Linux an unstable experience (though referring to "Linux" as a blanket term is nebulous and reductive to the point of irrelevance), but in the real world with real users, Windows is absolutely not a stable operating system, and far more difficult to diagnose and fix.

(edit) I almost forgot! We also had to push back an upgrade of the wifi infrastructure by a year because WPA3-Enterprise support on Windows was either broken or nonexistent on about a quarter of the computers. It was a fucking farce.
