Windows 7 has the ability to move windows around the desktop via the Windows key and cursors. However the way it does this is not to all tastes.

This app modifies it and brings the functionality to Windows XP as well. Now you can specify the number of rows & columns to span across each screen and move the window to the corners as well as by row & column.

Using the Windows key and the numpad gives the most control(cursor keys are still also supported)
'8' and '2' move the Window up and down a row.
'4' and '6' move the Window between columns
'1', '3', '7' and '9' keys move the Window into a corner.
'5' switches between centered, full screen and spanning all available displays.
'0' Minimizes the window

As long as this app is running (it will minimize to the task bar) the active window can be manipulated.
