Easy way to register Notification App (Name and Icon)

I figured there had to be an easy way to register an application via code with PowerShell 5.1 to display a custom toast notification name/icon for BurntToast. The function below will register the filled in details into the registry under the "HKCU:\Software\Classes\AppUserModelId", but as long as the machine is not locked down, the entry also gets added into "HKCR\AppUserModelId" which makes this all possible (From what I can see).

Once you have registered your "app", simply plug in the specified app name into BurntToast and enjoy!

From many other users, this seems to work on Windows 10/11 just fine 😊

Function - Register Notification App:

Function Register-NotificationApp {
    
    [CmdletBinding()]
    Param(
        [Parameter(Mandatory=$true)]
        $AppID,

        [Parameter(Mandatory=$true)]
        $AppDisplayName,

        [Parameter(Mandatory=$false)]
        [int]$ShowInSettings=0,

        [Parameter(Mandatory=$false)]
        $IconPath
    )

    $CurrentUserRegPath = "HKCU:\Software\Classes\AppUserModelId"
    If (!(Test-Path $CurrentUserRegPath)) {
        New-Item -Path $CurrentUserRegPath -Force
    }

    $RegPath = Join-Path -Path $CurrentUserRegPath -ChildPath $AppID
    If (!(Test-Path $RegPath)) {
        $null = New-Item -Path $CurrentUserRegPath -Name $AppID -Force
    }

    $DisplayName = (Get-ItemProperty -Path $RegPath -Name DisplayName -ErrorAction SilentlyContinue).DisplayName
    If ($DisplayName -ne $AppDisplayName) {
        $null = New-ItemProperty -Path $RegPath -Name DisplayName -Value $AppDisplayName -PropertyType String -Force
    }

    $ShowInSettingsValue = (Get-ItemProperty -Path $RegPath -Name ShowInSettings -ErrorAction SilentlyContinue).ShowInSettings
    If ($ShowInSettingsValue -ne $ShowInSettings) {
        $null = New-ItemProperty -Path $RegPath -Name ShowInSettings -Value $ShowInSettings -PropertyType DWORD -Force
    }

    If ($IconPath -and (Test-Path $IconPath -PathType Leaf)) {
        $null = New-ItemProperty -Path $RegPath -Name IconUri -Value $IconPath -PropertyType String -Force
    }

}

Usage Example:

Register-NotificationApp -AppID "AppCompany.AppName!App" -AppDisplayName "Sample Application Name" -IconPath "C:\SampleIcon.ico"
