防止停机 - C＃，Powershell或CMD / Bat

Question

I would like to ask how to prevent shutdown, when running a script or at least give a popup that will ask whenever or not you want to shutdown (like when you open a notepad and write a char, but doesn't save it and the click shutdown).

I have been creating scripts that runs installers silent, but some of them still seems to activate windows shutdown (this can happen if they are missing prerequisites).

Here is the code I use for the installation:

# --- Install ---
$fileExtension = (Get-ChildItem -path $installationFilePath).Extension

if(".msi" -eq $fileExtension)
{
    [string[]]$Private:args = New-Object string[] 4
    $args[0] = "/qn"
    $args[1] = "TRANSFORM=1033.mst"
    $args[2] = "REBOOT=Suppress"
    $args[3] = "/l*v $errorLogPath"

    $process = Start-Process $installationFilePath -ArgumentList $args -PassThru
}

if(".exe" -eq $fileExtension)
{
    [string[]]$Private:args = New-Object string[] 2
    $args[0] = '/v"' + "/qn TRANSFORM=1033.mst REBOOT=Suppress /l*v $errorLogPath" + '"'
    $args[1] = "/s"

    $process = Start-Process $installationFilePath -ArgumentList $args -PassThru
} 

$processActive = $process

while ($processActive -ne $null)
{
    Start-Sleep -Seconds 1
    Write-Host '.' -NoNewline
    $processActive = Get-Process -Id $processActive.Id -ErrorAction SilentlyContinue
}

I know this should be possible, but I have yet to find out how.

Here is an example of aborting shutdown after the install has finished:

Start-Process yourprogram.exe -Wait
shutdown /a

You could even loop the abort a few times to make sure you hit it.

for($i=0;$i -lt 5;$i++)
{
    shutdown /a
    sleep 1
}
