Hi Steve,
windows is probably in tablet mode, as it detects a touch-screen. To back to classic windows, or as close as win10 will go, press the square speech bubble thingy in the bottom right corner. Press the tablet mode button that is to the left of the pop-up. Then the normal desktop should be visible. You should be able to see things saved to desktop then. Otherwise, when HW is saving the file, you could specify somewhere else to save it, like "my documents".
