Change wallpaper script

Does anyone have a PS script to change the wallpaper for the test failover vm guests vpg’s? I’m looking to change up the look so the admins know they are working on a different environment as to not be confused with production when working with and testing the failover site and RDP’d into it.
If you’re failing over to a different hypervisor (ie VMWare –> Azure etc) it’s pretty simple to detect the change. We query (Get-WmiObject –query ‘select * from Win32_ComputerSystem’).Manufacturer on VM startup to see if the last scan matches the current value and if not we know a failover happened in one direction or another. Once you know true/false, replacing the wallpaper image is trivial.
Here is what someone else posted out on the internet:
$setwallpapersrc = @”
public class wallpaper
public const int SetDesktopWallpaper = 20;
public const int UpdateIniFile = 0x01;
public const int SendWinIniChange = 0x02;
[DllImport(“user32.dll”, SetLastError = true, CharSet = CharSet.Auto)] private static extern int SystemParametersInfo (int uAction, int uParam, string lpvParam, int fuWinIni);
public static void SetWallpaper ( string path )
SystemParametersInfo( SetDesktopWallpaper, 0, path, UpdateIniFile | SendWinIniChange );
Add-Type -TypeDefinition $setwallpapersrc
