not true, BitBlt is still able to access screen content on Win10 & 11

  Specifically, it can access screen content, but not window content. As in, passing in the desktop hwnd gets you a picture, passing in a different hwnd gets you a bunch of black. At least as of when I tried it a few months ago on Windows 10.

    Does the screen content contain all the windows that are visible, or is it the desktop image?

      All of the windows visible on screen. For my use case, I was taking a screenshot of my app (for automated testing), so I ended up taking a full desktop screenshot and cropping it to the window.

    I was curious about this so I just tested it... some windows are able to be captured and some are black
