First of all, applauds for the excellent work!

I want the set a wallpaper and using raw github url to fetch the wallpaper. Currently I am using this but it does work with Windows 10, but fails to set wallpaper on Windows Server 2008 R2. Any suggestions are welcome.

function RemoveWallpaper {
$code = @'
using System.Runtime.InteropServices;
namespace Win32{

 public class Wallpaper{ 
    [DllImport("user32.dll", CharSet=CharSet.Auto)] 
     static extern int SystemParametersInfo (int uAction , int uParam , string lpvParam , int fuWinIni) ; 
     
     public static void SetWallpaper(string thePath){ 
        SystemParametersInfo(20,0,thePath,3); 
     }
}

}
'@

Invoke-WebRequest -useb https://raw.githubusercontent.com/.....x.png -Outfile $env:temp\PSWall.jpg
$MyWallpaper="$env:temp\PSWall.jpg"
add-type $code
[Win32.Wallpaper]::SetWallpaper($MyWallpaper)
}

Hello Sir,
Instead of setting a bold Red wallpaper, I wanted to set a wallpaper from a raw GitHub page. How can I achieve this? I did try the code ( posted in the previous message) but it fails to work on 2008 R2. Any suggestions are most welcome!
