Possible to "snap" top/bottom instead of just left/right in Windows 7?

No. The only snap options available are:

  • left half snap (Windows + left)
  • right half snap (Windows + right)
  • full screen height snap (Windows + shift + up)
  • maximized snap (Windows + up)
  • "un-snap" (Windows + down)
  • snap to next monitor / display (Windows + shift + (left or right))

Edit: other awesome combinations you might like:

  • minimize all (Windows + m)
  • minimize all but active window (Windows + Home)
  • Aero peek (view Desktop, all Windows become transparent) (Windows + space)

I use the following steps to accomplish this:

  1. Windows + D (to minimize all windows)
  2. then use my mouse to place the windows I want to stack in the general placement on each monitor (don't bother resizing them)
  3. then right click on the taskbar and select "Show windows stacked" from the context menu then restore any other windows that I want

Note: You must minimize any windows that you don't want stacked. This is what step 1 is intended to do.
