Windows – Shortcut to resize and move a window to the upper-left corner / upper-right corner / bottom-left corner / bottom-right corner

Doing WINLEFT ARROW on application A and WINRIGHT ARROW on application B is a very cool and useful feature on Windows 7 to split the screen into 2 applications.

Now that I use it everyday, I would like even more (never happy!): is there a shortcut to resize and move a window to the upper-left corner / upper-right corner / bottom-left corner / bottom-right corner, so that the screen can be divided in 4 for different applications?

Something like:

WINLEFT ARROW once: move and resize to left half of screen

WINLEFT ARROW twice: move and resize to top-left quarter of screen

WINLEFT ARROW 3 times: move and resize to bottom-left quarter of screen

would do the job:

NB: I only have 1 screen.
