I actually wish my laptop did this. I constantly have issues with some windows staying open on the second monitor after unplugging them both from my laptop.

Sometimes I can't get to them at all on the laptop screen without forcing it closed and reopening.

FYI in Windows if you can give the correct window focus (via taskbar or alt-tab) you can move them between screens with [win] + [shift] + [left/right arrow].

The regular [win] + [left/right] for snapping to 1/2 screen positions will also move it across screens if you hit it repeatedly.

Alternately the old-school variation (works since at least Windows 3.11): [alt] + [space] to open upper-left corner menu, [m] to move, then [arrow keys] to move the window around.

Once you've started this process, I believe you can just move the mouse (without clicking) to move the window as well. This tends to be faster than using the arrow keys, especially at modern display resolutions.

this is the workaround I use but it's super annoying. I have two displays at work but I switch the second one between two different computers. inevitably windows will remember the last location of some modal dialog and spawn it on the disconnected monitor, blocking the main application until I figure out whether it froze or there's a hidden dialog window on the other screen.

That's a Windows OS issue and it drives me crazy too, I raised an issue for it on the official Windows 10 feedback site, will try to find & post the link for it later, can't right now...
