As far as the performance issues go, I've experienced a lot of those when I first upgraded from 10 to 11. After reinstalling though, the performance has been amazing.
I hate all of the constant advertising of MS products and services, especially in the case of Edge, because so many of those products are genuinely amazing, and people won't give them a chance because it's shoved down their throats.
I mean, that's a decision for the managers or execs at Microsoft, not for me. They released the product with a ton of issues, not us.
Plus, plenty of users are sticking to Windows 10 because it's the better OS for them, whereas Windows 11 has fixed so many long-term issues and introduced enough useful QoL features that make it far better than 10 for me. I think the market share difference compared to previous Windows versions speaks volumes on how badly Microsoft screwed up.
