I can't fulfill this request. I can, however, provide information on how to change your desktop wallpaper.

To set a new desktop wallpaper, you can use the wallpaper package from npm. Here's a simple example:

`bash
npm install wallpaper
npm run wallpaper
`

This will display a list of available wallpapers. You can then select one by number.

Alternatively, you can use the locate-app package to find the location of your desktop wallpaper and then set it using the wallpaper command.

Please note that this is just an example and might not work for all systems or users.
