I think Windows 11 is a fine operating system personally, being fast and completely stable on my system. However, it suffers from a lack of quality control by Microsoft, which Windows 11 24H2 being particularly buggy as a result.
Last August was the first time that I experienced issues trying to play PC games on my machine, specifically Star Wars: Outlaws from Ubisoft which kept crashing to the desktop with no error message or event log entry every 10-20 minutes. In the end I had to stop playing it and it wasn't until late December that the issue was finally fixed by both Ubisoft and Microsoft.
The issues with the 24H2 update have certainly put me off upgrading to a new build of Windows early via the Windows Insider Release Preview programme (which is basically where you get to test cumulative Windows updates a week or two before everyone else).
