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.
