Windows Terminal version

94e6b91c78

Windows build number

10.0.19045.3086

Other Software

cmd.exe, powershell.exe or any .bat file to start cmd - anything that opens a terminal.

Steps to reproduce

  1. Make Windows Terminal the Default terminal application in settings.
  2. Make sure that New instance behavior is Create a new window.
  3. Set "firstWindowPreference": "persistedWindowLayout" (When Terminal starts: Open windows from a previous session)
  4. Open a few tabs.
  5. Open a .bat file from explorer or start cmd/powershell from the start menu or Win+R.

If opening .bat files behaves as expected, close all Terminal windows, open it again and try running .bat once more. It makes the issue reappear if for some reason it starts working correctly.

Expected Behavior

A new window opens, in which the file is executed.

Actual Behavior

Two new windows open:

  • one in which the file is executed
  • one with the same tabs as in the existing window

I think it may have something to do with #15509, because process explorer shows two different Terminal process trees:

The older Terminal - under explorer.exe (1 window):
Windows Terminal from explorer.exe

The reopened Terminal - under wininit.exe -> services.exe -> svhost.exe (2 windows - cmd and reopened):
Windows Terminal from svchost.exe

The cmd.exe launched from Win+R, which caused Terminal to start again is under explorer.exe:
cmd.exe
