If you use an X Server and environment to launch programs inside WSL2, what part produced by Microsoft is still providing some value to that setup? Wouldn't you just exec ELF programs to be run on top of the Linux kernel and Windows would be just some useless abstraction layer between the Linux kernel and the hardware? Or would you still use some actual Windows programs? How would that work with the X Server?

There was some utility I found a few years ago that would let me start an X Server and use it to replace the main explorer process. There was some support for standard Windows apps due to the background System processes still running. I think it ended up running the Windows desktop shell as a window in and of itself.

I wanted to use a tiled window manager and my dot files for continuity purposes. The Windows apps I need to use are stuff like anyconnect and Teams.
