Can I take a snapshot of my wallpaper?

I have Windows 10. When I start up my laptop, I see beautiful scenes on my wallpaper (not screen saver) that I would love to capture and post some on a social media forum.

I have not been here in a long time, so I updated my signature. If you need more information to solve this, let me know.

Thank you!

Wallpapers are usually pictures built into windows you can track down on the hard drive. The new Windows 10 Lock screen "wallpapers" have a link that says "Do you like what you see?" Which will take you to the source of the image.

Thank you James !
