"Windows" is the combination of the OS per se and all the things needed for it to run properly. That thing is a mess of proprietary drivers and pieces of software cobbled together. It can't be called "high reliability" with a straight face.
Anecdotally, I have zero stability problems on my non-ECC consumer-grade 11th gen Intel Windows 11 system. It'll stay up for months, until I decide to shut it down. I had a loose GPU power cable that was causing me problems at a point, but since I reseated everything I haven't had a single issue. That was my fault, things happen. The system is great.
More significantly, I see no difference in stability between our Windows Server platform and Red Hat Enterprise (Oracle) server platform at work either. Work being one of the top 3 largest city governments in the USA.
didnt red hat have a massive DEI/anti white man scandal? I wouldnt trust their products
the smartest people use and maintain Arch, ergo everything should run on Arch for maximum stability
The problem is the middle management class at hospitals, governments, etc., only know how to use Word and maybe Excel, so they are comfortable with Microsoft, even though it's objectively the worst option if you aren't gaming. So then they make contracts with Microsoft and all the computers run Windows, so all the app developers have to write the apps for Windows.
