# Force Reboot

There may be instances where workstations are not joined to a domain. These devices might not be rebooted for long periods, resulting in a lack of updates.  This script can be set in Task Scheduler to run on a scheduled basis. It notifies the user that a reboot needs to take place and gives them the option to reboot now or remind them later. After delaying the reboot two times, the script prompts the user to save their work and reboot.

```powershell
$delayCount = 0

# Loop to allow the user to delay reboot twice
while ($delayCount -lt 3) {
    $choice = [System.Windows.Forms.MessageBox]::Show(
        "There are new Windows updates available. Please choose one of the following options:`n`nClick Yes to install updates now and reboot immediately.`nClick No remind me later.",
        "Reboot Required",
        [System.Windows.Forms.MessageBoxButtons]::YesNo,
        [System.Windows.Forms.MessageBoxIcon]::Exclamation
    )

    if ($choice -eq [System.Windows.Forms.DialogResult]::Yes) {
        # Reboot the computer
        Restart-Computer -Force
        break
    } else {
        Start-Sleep -Seconds 3  # Delay for 1 minute
        $delayCount++
    }
}

# If user delayed twice or closed the warning box, force reboot
[System.Windows.Forms.MessageBox]::Show(
    "WARNING: You have no other option but to install updates now to keep your system secure. Please save your work.`nThe computer will restart automatically after installation is complete.`n`nThis may take a few minutes.",
    "Reboot Required",
    [System.Windows.Forms.MessageBoxButtons]::OK,
    [System.Windows.Forms.MessageBoxIcon]::Warning
