XdN Tweaker 0.9.1.4 has been released with improved support for Windows 7 (including the public RC build 7100).New features include the ability to disable "Drag from Maximize" and other window arrangement features like "Aero Shake" and dragging a window to the side of the screen to maximize or tile it vertically.
It still works with Windows 2008/Vista/2003/XP as well. If used with Windows 7, a newer build like 7077 or 7100 is recommended.
