Turn off Aero Snap

A new feature in Windows 7 is Aero Snap, which causes your application windows to automatically snap into a preconfigured place when you move them to the edges of the screen. Drag a window to the far right, and it will size itself to fill exactly half the screen. Drag it to the top corner and it will maximize to fill the whole screen. This can be handy, but it can also be annoying if you prefer that your windows stay the size you made them. Luckily, you can easily turn Snap off. Here’s how:

1. Click Start and select Control Panel.
2. Click Ease of Access Center.
3. Click Make the Mouse Easier to Use.
4. Select the Prevent Windows From Being Automatically Arranged When Moved To The Edge Of The Screen check box and click OK.
