4 Ways to Disable Automatic window Resize Feature in Windows 10

Windows 10 comes with a nifty feature for arranging open windows by snapping into the corners of the screen. This is a great feature as the users can arrange windows on the screen such that all windows are visible on screen.

This feature is designed for user convenience. But for some users, it can be annoying especially when the laptop screen is small. The users can unintentionally drag the window to any corner of the screen and the window will snap to the corner automatically.

If you want to disable this window auto-resizing feature in Windows 10, please check our four ways to disable the automatic resizing feature.

Disable window Auto-resizing using the Settings App

This is a basic way to disable the auto-resizing of the windows. In Windows 10, open up the Start Menu and click the Settings icon.

From there, click System and navigate to the Multitasking tab on the left-hand menu. Here, you will find a Snap Windows toggle button which can be turned off to disable the automatic window resizing.

Disable the window resize feature from Control Panel

Another method to disable the auto-resizing of the windows is via the Control Panel.

In this scenario, open up the Control Panel and navigate to the following destination:

Ease of Access –> Ease of Access Center –> Make the Mouse Easier to Use.

At the bottom of the screen, check Prevent windows from being automatically arranged when moved to the edge of the screen.

By checking this box, the auto-resizing of the windows will cease when dragged to either of the edges.

Disable window resize using Command Prompt

With the aid of the below shown commands, we will be disabling the Snap Window slider, but without having to navigate to the Multitasking window itself.

This can be achieved by running the following commands on Command Prompt. To open the Command Prompt, press the Windows Key simultaneously with R, and then type cmd and press enter.

This method requires us to run four individual commands; three for each check box under the toggle button in Windows Settings app, and one for the toggle button itself.

  1. We shall begin by disabling When I snap a window, automatically size it to fill available space with the following command:
    reg add HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V "SnapFill" /T REG_DWORD /D "0" /F
  2. Disable When I snap a windows, show what I can snap next to it with the following command:
    reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V "SnapAssist" /T REG_DWORD /D "0" /F
  3. Disable When I resize a snapped window and simultaneously resize any adjacent snapped window with the following command:
    reg add “HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced” /V “JointResize” /T REG_DWORD /D “0” /F
  4. Now we shall disable the Snap Windows toggle button with the following commands:
    reg add "HKCU\Control Panel\Desktop" /V "WindowArrangementActive" /D "0" /F

This method might not be the most convenient one, as we are performing the same task as Method 1 with commands, instead of the conventional Graphical User Interface. This can be useful for sysadmins and power users and for automating the task by using group policies across the network.

Disable auto-resize using Windows Registry

This method involves modification of the Windows Registry, which completely disables automatic window resizing.

Similar to Method 3, this method also addresses the four features individually. The .bat files below can be downloaded and used as described to disable the auto-resizing of windows:

  1. For disabling When I snap a window, automatically size it to fill available space:

  4. To enable Snap Windows:

    Windows 10 (build 19041.746 resizes windows over night, sometimes so much they cannot be found (I never snap windows). How can this be disabled?

      Do you have multiple monitors connected to your computer?

      • Micha February 1, 2021, 2:14 AM

        Yes… I use two, one in landscape mode, and one in portrait; I suspect this is what causes much of the problem, but if I could get rid of the system insisting on reducing the size which are out of sight (but no, not out of mind), there should be no problem. Just to mention, I do not “snap” windows.

        Any idea what could cause that?

        Thanks…………………..Micha

          This usually happens when there are two screens connected and they don’t have similar resolutions. The quickest way I can think of to bring back the window is to make it active using Alt + Tab and then pressing Alt + Space + X to maximize the window or Alt + Space + M to move the window to a visible area.

    You are right about annoying and extremely irritating. Very often I am need to read some matter from one window and fill in some form or mail. The stupid thing would suddenly change the window size and hide the part that I need to read.

    Have made the changes through settings. Just hop it works for me. It would have saved me so much heart burn if I had found this earlier.

    THSNK YOU VERY MUCH !!!
