There are so many breaking changes to Windows 11, especially to user interface which ruins power user's (or any user's) experience.
Some examples include: - Alt-Tab does not work like it used to; it's worse imo - Context menu is very different, less accessible - Folders behave differently - Task bar cannot "never combine" windows like why the hell would you remove features
I see so many breaking changes most of them without a way to revert, or need to go through burning hoops to change. most guides saying to change 10 options in registry often don't even work.
I miss Windows 7. I will even settle for 10 now...
Also I recommend reading this post about UI inconsistencies in Windows 11: https://ntdotdev.wordpress.com/2023/01/01/state-of-the-windows-how-many-layers-of-ui-inconsistencies-are-in-windows-11/
