Is there a way to change the default shell in Windows Terminal?

Question

When opening the new Windows Terminal, it opens up PowerShell. Also by default new tabs are PowerShell.

You have to manually switch to your desired shell.

Is there a way in the settings JSON file to change this to cmd or something else?

Answer 1

Open Windows Terminal JSON settings. Next, in profiles array find the object for the shell you're searching and copy the guid value from it. The last step is to paste this value into the defaultProfile attribute.

{
    "$schema": "https://aka.ms/terminal-profiles-schema",

    "defaultProfile": "{0caa0dad-35be-5f56-a8ff-afceeeaa6101}"

    ....

It may change your default shell.

The procedure requires some knowledge about JSON file format. Here is a brief outline. Every member is represented as "name":"value" pair. Arrays use square brackets and Objects use curly brackets. Read this Wikipedia: JSON for more details.

Procedure:

• Open Windows Terminal. Click on the down arrow symbol ˅ from menu bar. This will open a drop down menu from which select Settings option. Alternatively use Ctrl + , to open Settings directly. Here is a sample screenshot:

• After selecting the Settings, Notepad (or the default text editor) will open profiles.json file. Here is a sample, see first JSON object i.e. "globals".

"globals" : 
{
    "alwaysShowTabs" : true,
    "copyOnSelect" : false,
    "defaultProfile" : "{12345678-1234-1234-1234-1234567890AB}",
    "initialCols" : 120,
    "initialRows" : 30,

We are interested in defaultProfile name. The value with 128-bit format {12345678-1234-1234-1234-1234567890AB} is called UUID. Assume its like a nickname for default shell :)

• Now in that file, find "name" : "cmd" pair (or "commandline" : "cmd.exe" pair) for Command Prompt. There will be a "guid" pair adjacent of it. Copy the value, i.e. the 128-bit nickname. And paste it to globals > defaultProfile.

• Restart Windows Terminal.

If you have installed Windows Terminal without Windows Store, the actual path of the profiles.json is "%LocalAppData%\Microsoft\Windows Terminal\profiles.json". You can directly open the path in any text editor.

Edit settings and change the defaultProfile value to the GUID value of the profile you want to be the default. For example:

{
"$schema": "https://aka.ms/terminal-profiles-schema",

"defaultProfile": "{d3f31bee-5823-5ed8-8e04-f31ed54f2cd9}",

This setting is now available in the UI. Open Windows Terminal settings using the drop-down in the title bar and click Settings. In the Startup section you can change the default terminal. You can select the classic Command Line, Powershell and also Git Bash or WSL distro shells if any are installed.
