Adjust Windows Snap Assist Sensitivity in Regedit

This guide explains how to fine-tune the sensitivity of the Windows Snap Assist feature using the Windows Registry Editor. By modifying specific values under your user desktop settings, you can control the drag distance required to trigger window snapping, preventing accidental edge-docking or making the feature trigger more quickly depending on your preference.

Step 1: Open the Registry Editor

  1. Press Windows Key + R to open the Run dialog box.
  2. Type regedit and press Enter.
  3. Click Yes if prompted by User Account Control (UAC).

Step 2: Navigate to the Desktop Configuration Key

In the Registry Editor address bar at the top, paste the following path and press Enter:

HKEY_CURRENT_USER\Control Panel\Desktop

Step 3: Modify the Snap Sensitivity Value

  1. Look for the string value named DockMovingThreshold in the right-hand pane.
  2. If DockMovingThreshold does not exist:
    • Right-click an empty space in the right pane.
    • Select New > String Value.
    • Name the new value DockMovingThreshold.
  3. Double-click DockMovingThreshold to edit its value data:
    • Default Value: 30 (or unset on some systems).
    • Increase Sensitivity: Enter a lower number (e.g., 10 to 20), which makes windows snap with less drag distance toward the screen edge.
    • Decrease Sensitivity: Enter a higher number (e.g., 40 to 60), requiring you to drag windows further past the screen boundary before Snap Assist activates.
  4. Click OK to save the changes.

Step 4: Apply the Changes

Registry changes to the desktop shell do not take effect immediately. To apply the new sensitivity settings:

  1. Press Ctrl + Shift + Esc to open the Task Manager.
  2. Locate Windows Explorer in the list of processes.
  3. Right-click Windows Explorer and select Restart.
  4. Alternatively, restart your computer.
