A loopy sign-on script I had a lot of fun writing for Internet Explorer (RIP). This was originally written for Windows-based "digital signage" displays that would show a printer's queue from its webpage via IE, refresh the page every 60 seconds via method, and handle relaunching were the browser to crash.

Invoke-IEKiosk.ps1

$URL = ""
$targetprocess = "iexplore"
$process = Get-Process -Name $targetprocess -ErrorAction SilentlyContinue

# Infinite loop
while ($true){
    # Initial launch of the application
    # While the process is not running
    while (!($process)){
        $process = Get-Process -Name $targetprocess -ErrorAction SilentlyContinue
        # If the process STILL isn't running or has crashed
        if (!($process)){
            # Invoke IE ComObject with properties set for the URL specified, kept in front of all windows, and in full-screen mode
            $ie = New-Object -ComObject InternetExplorer.Application -Property @{navigate2=$URL; visible = $true; fullscreen = $true}
        }
        # Wait between attempts to make sure the process is still running.
        start-sleep -s 5
    }
    # If/while the process is running...
    if ($process){
        # Don't proceed unless the process exits...
        # https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.process.waitforexit?view=net-5.0#System_Diagnostics_Process_WaitForExit
        $process.WaitForExit()
        # If it does exit, wait a moment before calling it again
        start-sleep -s 2
        $process = Get-Process -Name $targetprocess -ErrorAction SilentlyContinue
        $ie = New-Object -ComObject InternetExplorer.Application -Property @{navigate2=$URL; visible = $true; fullscreen = $true}
        # Regardless, while the process is running, refresh the page every minute
        while ($true) {
            Start-Sleep -Seconds 60
            $ie.Refresh()
        }
    }
}
