Virtual desktop preview

20 Mar 2018, 09:32

Hi,
Windows 10 has a built-in live preview of active virtual desktops (activated by Win+Tab), that looks like this:

Now I was wondering, is there any way to access a particular desktop preview and draw it in a GUI?
I want to be able to use my first desktop, while having a little preview on what's on the second desktop:

If you have any ideas, please share with me!
Thanks in advance

Hey,
Unfortunately this only shows what windows are open on a particular virtual desktop.
I'm looking for a way to get the actual image of what's on the second desktop, so I can redraw it.

Is there a way to take a screenshot of another virtual desktop?

I've managed what I needed to do with GDI's Gdip_BitmapFromHWND on a fullscreen application on a virtual desktop and it works, a bit CPU-intensive though.

Possibly you could use dwm. It will be much lighter on CPU.

Cheers.
