How to change the desktop wallpaper from powershell.

Powershell change wallpaper

set-itemproperty -path "HKCU:Control Panel\Desktop" -name WallPaper -value accipiter.png

Is there an updated version of this command or is the consensus in 2022 (going into 2023) for changing wallpapers from PowerShell is to never do it and just use the UI to do it? I kind of want to be able to change my wallpaper from telescope.nivm and the first step is to be able to do it in PowerShell. Can I get a feel on what the opinions on this

@gabrielkryss You can put BirkhoffLee's post above in a ps1 file like so:

# Note: if scheduling this script, you may need to check 
# that the powershell session is logged in as the user

$path = $args[0]

$setwallpapersrc = @"
using System.Runtime.InteropServices;

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

[Wallpaper]::SetWallpaper($path)

And call it like so:

wallpaper.ps1 D:\wallpapers\wallpaper.jpg

Or you could keep your wallpaper at a specific location (e.g., $env:LOCALAPPDATA\wallpaper.png) and have your script simply set that path as the wallpaper.

Is there a way to get these awesome scripts to work for an entire DIR, instead of single file?

Cheers
