Aero Snap is a new feature in Windows 7 wherein the windows will automatically arrange (dock) when moved to the edge of the screen. When you drag a window to the left side of the screen, it will automatically dock to the left side of the screen taking half of the screen space. The same goes for the right side. When dragged to the top of the screen, the window maximizes.

3. Click one of the following options:

  • Make the mouse easier to use

4. Place a checkmark near the following option:

Prevent windows from being automatically arranged when moved to the edge of the screen

5. Click OK, and close the Ease of Access Center

    I wish it was possible to only turn off the annoying maximize snap (top edge). The others are actually quite useful (and not immensely annoying like the maximize)….

    This was exactly what I was looking for. I don’t think the people stating they couldn’t get this to work are actually having this problem. It is very simple. Also, I used two screens and it works fine. I was fooling around with settings a few days ago and couldn’t remember where it was that I made the change. I unchecked it because I love the snap feature. Thanks for the help!!!

    this is like several other sites-worthless. I have been looking to download Aero-snap and i get shuttled to everything but the SNAP download. even Microsoft gives me the run around. I think this is a ruse by advertisers to promote their product

    To be honest this didn’t help me at all! I followed the directions that you have and identical directions on another website. I can’t get my window to snap the right or left when i drag it to the edge. When I drag it to the edge it just expands to fill the whole screen. I did find an answer on my computer that made it work and that was that I just had to hit the “windows key” and the right or left arrow on my keyboard at the same time and it worked!

    This answers a question I had on a MS Windows help forum. Thanks!

    I tried to use this and got the two windows up, but when I tried to get the second window to download information needed all I could get was a black screen divided in the center for the left side window. The right side was fine and showed what I needed.

    I did this, but on my dual monitors, if a window is between the two monitors, it still jumps to the first monitor edge if I do anything.
