How to Shut Off Windows 7 Aero Snap – Stop it from Auto Arranging Windows


Window’s 7 new Aero Snap feature is, no doubt, a useful feature for those with just one monitor. In my case, where I use multiple monitors, it is a major pain. Windows 7 frequently auto-adjusts windows across multiple monitors when I have no desire for this to happen.

In the picture above, my Firefox window was originally open in just the lower, central, window. I was dragging the lower right corner with my mouse (see yellow arrow) to adjust the window when, suddenly, it popped up across three monitors (see four red arrows above). Yikes!

Windows 7 does this because it thinks that if you drag an edge of a window to the edge of a screen (any screen) you want the widow stretched across the full screen (or in my case, multiple screens). Nobody would want the result produced above.

Before disabling Aero Snap this happened to me several times a day. It doesn’t any longer. To disable Aero Snap, follow these steps:

  • Go to Control Panel
  • Select ‘Ease of Access Center’
  • Select ‘Make the mouse easier to use’
  • Check ‘Prevent Windows from being automatically arranged when moved to the edge of the screen’


  • Click ‘Apply’
