Whenever I drag or resize a window near any edge or corner of either monitor, Windows wants to maximize or resize the window for me in several different ways:

  • dragging a window near a corner offers resize to full-screen
  • dragging directly to the corner offers half-screen maximize
  • resizing to top or bottom edges offers a vertical maximize (one long strip from top to bottom)

Actually, now that I think about it the 3rd one isn't so bad, its just the full and half-screen maximize features that drives me mad.

Is there a registry hack to disable these settings, preferably independently?

This drives me nuts. It's a great feature for looking at two windows side by side easily and I don't know why it took until Aero for MS to introduce it, but I want it to work only when dragging a window's titlebar, not when dragging window edges. It should also be an option in the window management (i.e. top left corner) menu. –  John Ferguson Mar 14 '14 at 9:29

This Windows 7 feature is called Aero Snap. Here's the easy way to disable it completely:

  1. Go to Control Panel.

  2. Click on Ease of Access link or Ease of Access Center icon.

  3. Select Change how your mouse works or Make the mouse easier to use option.

  4. Tick the check box for Prevent Windows from being automatically arranged when moved to the edge of the screen with the mouse under “Make it easier to manage windows” section.

And here's the roundabout way via the registry:

  1. Run Registry Editor (RegEdit).

  2. Navigate to the following registry key:

    HKEY_CURRENT_USER\Control Panel\Desktop
  3. In the right-pane, double click (or right click and select Modify) on WindowArrangementActive, and set its REG_SZ value to 0 to disable ; 1 to enable.

  4. Close Registry Editor.

  5. Log off and log on again, or restart computer for the change to take effect.

Hope this helps! I haven't found any way to retain functionality for a single edge - it's either all on or all off.

The first method disables Win+R & Win+L key functionality for me. Is there a way to just disable auto maximize when Window touches the top edge of screen while preserving the snap to left/right functionality. –  buffer Jun 29 '13 at 6:20
