> a lot of the Windows shell and apps have been slowly rewritten in C#
I worked on the Shell team until late 2022. There is very little C#, if any at all. The vast majority of the Windows Shell is still C++ with a significant amount of WinRT/COM.

What I had in mind when I wrote this sentence though is how the modern apps that people seem to like /are/ C#, such as Windows Terminal and PowerToys, and these feel quite slow to me. But, yeah, calling those the shell is a stretch.
PowerToys is mostly C# though, which I have also verified now.
