Export Drivers.ps1

<#
.SYNOPSIS
    Exports all installed Windows drivers to a folder named after the device's serial number.

.DESCRIPTION
    This script performs the following actions:
    - Checks if it's running with Administrator privileges; if not, it restarts itself elevated.
    - Determines the script's starting location.
    - Retrieves the device's serial number using WMI.
    - Deletes any existing driver export folder with the same serial number.
    - Creates a new folder named "Drivers_<SerialNumber>" in the script's directory.
    - Exports all installed drivers to that folder using Export-WindowsDriver.

.NOTES
    - Requires Administrator privileges.
    - Compatible with Windows 10/11 and Server editions that support Export-WindowsDriver.
    - Must be run in an elevated PowerShell session or will auto-restart elevated.
