As we can see, while there are definite improvements in Windows 11’s design consistency, they are somewhat superficial (but still more thorough than those that were introduced with Windows 10), and there still is plenty of room for improvement. However, compared to Windows 10, at least most of the “casual” UI is somewhat consistent.

In 2023 Windows 11 will reportedly get 3 of the new “moment” updates, which are supposed to bring in new features and UI fixes. Not only that, but Microsoft is thought to be working on decoupling the UI elements from the rest of the OS even further, so we should probably see more improvements more quickly.

The conclusion of this excellent article about Windows 11 UI design inconsistencies is a bit off compared to the rest of the article. You really have to have a look for yourself. Windows, as it is shipping today, contains a plethora of previous-generation UI design languages, all packed together. When I look at macOS, I fail to find any similar example. Now, my question: why can Apple change everything in the UI (like when they introduced macOS BigSur) and not keep old UI designs? What is Apple doing differently? Is macOS easier to maintain than Windows? Or is it because Microsoft simply doesn’t care enough?
