Why do I directly double-click the cmd.exe file in the System32 directory, it will also open in Windows Terminal? How is it achieved? Ask for answers

What is your default terminal application? Check settings of Windows Terminal or conhost.exe. In my settings "Let Windows decide"

Win+R > conhost

Change the default terminal applications and check values in the HKCU\Console\%%Startup registry key.

You deleted console host settings for Windows\System32\cmd.exe (color, size, font etc) This out of subject.

In my environment all works as expected (win 11 22H2).

  • set default terminal application
  • relogin (maybe no need to do)

@zadjii-msft commented on GitHub (Aug 21, 2023):

What you're seeing is the "Default Terminal" feature in Windows 11, which lets you change which application is used as the default terminal emulator for command-line applications. That was previously always "conhost.exe", but now the Windows Terminal can be used as the default emulator too.

How it works is... complicated... and I believe we're tracking writing those docs in #9462. It was originally spec'd here: #7414

The other comment you have in this thread, about the leading spaces, looks like it's the same thing we're discussing with you in #15836, so I'm gonna collapse that as off-topic.
