The interesting thing is that Windows 11 was not nearly this bad when it released. People forget because it was disliked at launch, but alot of those complaints were over things like taskbar placement. Minor changes that people will always bitch about but will realistically adapt to. I even would argue it had some decent improvements, like adding tabs to notepad and the file explorer, which were small but nice QoL additions. People dislike change, but it was really just more Windows 10 with a different skin.
Somewhere over the past few years, Id say around 23H2 or 24H2, it has gotten astronomically worse. Windows always had some issues, Ive seen most installs slow down over time, get small bugs due to weird registry mismatches, etc. But over the past few iterations there are constant reports of serious bugs, and even clean installations have immediate issues. MS is also constantly fucking the customer with poor decisions and AI marketing gimmicks. Complete and utter trash fire.
