When I press Windows+left-key or Windows+right-key, the active window snaps to the left or right side of the screen. However, when I do this, I get a selection of windows which also could be "snapped" - I found that this feature is called "snap assist".

I know how to turn it off (in settings -> system -> multitasking), but I'd like to turn it off via command line. The reason is because this needs to be disabled on a lot of computers, and I can simply add it to a script that is run on each of those computers anyway.

How can I turn off this feature via command line? Please note that I want to disable the snap assist feature, not snap assist itself.


Using Command Prompt:

  • Disable "When I resize a snapped window, simultaneously resize any adjacent snapped window":
reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V "JointResize" /T REG_DWORD /D "0" /F
  • Disable "When I snap a window, show what I can snap next to it":
reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V "SnapAssist" /T REG_DWORD /D "0" /F
  • Disable "When I snap a window, automatically size it to fit available space":
reg add "HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /V "SnapFill" /T REG_DWORD /D "0" /F
  • Disable "Snap windows" toggle button:
reg add "HKCU\Control Panel\Desktop" /V "WindowArrangementActive" /D "0" /F

Using Registry file:

Create a blank text file in any text editor (e.g. Notepad). Copy-paste the following section. Then change the extension from .TXT to .REG. Double click on that REG file to import the settings.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Control Panel\Desktop]


Restart PC to make it affect.

This setting can be modified using the registry. You can create/modify the key SnapAssist which is a DWORD value. It is located/you should place it here:


0 is off, 1 is on.

You can then export it to a .reg file for deployment via a command-line, or from a batch script. You can use reg import sample.reg to apply it to another computer via flash drive or network share, just as an example.
