win + shift + arrow stopped working on Windows 10. It should move Windows to adjacent screens.
I looked at the WM_HOTKEY events with Spy++ as described in How can I determine which process owns a hotkey in Windows?. There weren't any!
I remembered having changed some multitasking setting in Control Panel a short while ago. Turns out that the win + shift + left/right arrow hotkeys are only available if "Arrange windows automatically by dragging them to the sides or corners of the screen" is enabled under "Multitasking" in Control Panel.
PS. There still aren't any WM_HOTKEY events when I use the hotkey. Apparently it uses some other mechanism to capture the events.
