y tho

Is this really a bug, or expected behavior? I bet your default profile for the Terminal is a cmd.exe profile. Whenever you launch cmd.exe, Windows is going to open a new WT instance, which is going to start cmd.exe as your default profile, which is going to cause Windows to open a new WT instance, ...

This is very much by-design. Do you have some other design or use case in mind?

Yes, when I use the command cmd.exe, I want to open a WT instance instead of system32\cmd.exe
