Answer 1

For Win10 UWP I noticed that the CTRL and SHIFT keys were set at Locked state. So I did the following:

var shiftState = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Shift);
var ctrlState = CoreWindow.GetForCurrentThread().GetKeyState(VirtualKey.Control);

var isShiftDown = shiftState != CoreVirtualKeyStates.None;
var isCtrlDown = ctrlState != CoreVirtualKeyStates.None;
