Windows 7 Aero Snap two windows horizontally [duplicate]
Solution 1:
The following method worked for me: Minimize all windows except the two which you want to have stacked on the screen, then right click on the task bar and use the "Show windows stacked" option. It will only stack the windows that are not currently minimized. Later, you can restore the rest of the windows as per your requirement.
Solution 2:
You can now use WinSplit Revolution with its Virtual numpad option: Options -> Virtual numpad -> Show Virtual numpad at starting
It will give you a small on-screen 'numpad' (arrow-pad) which you can use to position your windows (works with touch screen or pen as well).
Solution 3:
The answer is:
No, there is no Aero Snap feature to snap two windows horizontally, stacked on top of each other.
While there might be 3rd party software to achieve what you want, Aero Snap cannot do it.
