Unfortunately, Windows 10 does not come with the feature to position your windows to upper / lower half of the screen.
What is possible though is:
Keys - Operation
Win + Left - Position a window on the left half of the screen
Win + Right - Position a window on the right half of the screen
Win + Up - Maximize a window
Win + Down - Restore a window, Minimize a window
Win + Shift + Up - Snap a window to maximum height
Win + Left / Right then Win + Up / Down - Position a window to one of the four possible quadrants
Win + Shift + Left / Right - Shift a window to the next / previous display
Win + M Minimize all windows
Win + Home Minimize all but active window
Win + D Toggle Desktop View
Hope this helps you.
