How to remove powershell ads and update checks in the Windows Terminal?

When I start the Windows Terminal, I get the following:

How do I get rid of the copyright & version notifications, the help URL and the update check? I just want to get to the command line.

My powershell profile in the settings.json (the config file for the Windows Terminal) is like this:

{
    "guid": "{574e775e-4f2a-5b96-ac1e-a2962a402336}",
    "hidden": false,
    "name": "PowerShell",
    "source": "Windows.Terminal.PowershellCore",
    "fontFace": "Cascadia Code PL",
    "startingDirectory": "C:\\Users\\user1\\desktop\\"
}

I've seen flags like -nologo and so forth, but I don't have a command line to pass it to.

Update:

• The answer below shows you to directly edit your settings.json file.

• As of at least Windows Terminal 1.16, you can alternatively use the GUI:^{Thanks, Chris}

  • Open the Settings tab (e.g. via Ctrl-,)
  • At the bottom of the sidebar on the left, click + Add a new profile, and, next to Duplicate a profile, select your existing PowerShell (Core) profile, then press the Duplicate button.
  • Click on Command line, and modify the existing command line by appending -nologo, as also shown below.

• An alternative to solving your problem via a Windows Terminal profile is to modify your system to persistently define an environment variable named POWERSHELL_UPDATECHECK with value Off, which you can do as follows (requires restart of Windows Terminal via the Start Menu / taskbar to take effect):^{Thanks, SodaCris.}

  [Environment]::SetEnvironmentVariable('POWERSHELL_UPDATECHECK', 'Off', 'User')
  

Create a custom profile in Windows Terminal's settings.json file as follows (inside the profiles.list array property):

As of at least PowerShell 7.2.1 -nologo also deactivates update notifications:^{Thanks, Maximilian Hils.}

{
    // no strict need for a GUID; create a *new* one, if needed.
    "hidden": false,
    "name": "PowerShell - no logo, no update notification",
    "commandline": "pwsh.exe -nologo"
    // ... other properties omitted.
},

In earlier versions you may need environment variable POWERSHELL_UPDATECHECK to disable update notifications:

{
    // no strict need for a GUID; create a *new* one, if needed.
    "hidden": false,
    "name": "PowerShell - no logo, no update notification",
    "commandline": "cmd /c set POWERSHELL_UPDATECHECK=Off & pwsh.exe -nologo"
    // ... other properties omitted.
},

• Copy the startingDirectory and fontFace properties from the dynamic profile shown in your question, if desired. (Dynamic profiles are auto-generated by Windows Terminal itself, depending on what shells are found to be installed; they have a source property whose value starts with Windows.Terminal, as in the entry shown in your question.

• There is no strict need for a guid property in this case (generally, names and GUIDs can be used interchangeably to identify a profile); if you do use one, create a new GUID (e.g. with New-Guid).

  • If you want to use the same name value as that of the dynamic PowerShell Core profile, it's best to hide the latter by setting its hidden property to true.

• Custom profiles use a commandline property to define what command to execute when a tab with this profile is generated. The value above assumes that PowerShell's executable, pwsh.exe, is in your path; if it isn't and you therefore need to specify a full path, be sure to either double \ chars. (e.g. \"C:\\Program Files\\PowerShell\\7\\pwsh.exe\") or use / instead (e.g. \"C:/Program Files/PowerShell/7/pwsh.exe\")

• May be required in PowerShell versions before 7.2.1:

  • cmd /c set POWERSHELL_UPDATECHECK=Off defines the relevant environment variable to turn off PowerShell's update notifications, and then launches PowerShell.

    • This means that your PowerShell instances will have a cmd.exe parent process, but that shouldn't be a problem.

  • You can alternatively define this environment variable persistently, via the registry, in which case cmd.exe is no longer needed.

• Passing -nologo to PowerShell's CLI suppresses the "logo", i.e. the copyright message and help hint.

  • As of at least PowerShell 7.2.1, -nologo automatically deactivates the update notifications as well - potentially, it has always worked this way.
