Change Mouse Double-Click Speed via Regedit

Adjusting your mouse double-click sensitivity through the Windows Registry Editor allows you to fine-tune both the timing and the spatial movement thresholds required to register a double-click. While the Windows Settings menu offers basic sliders, modifying the Registry directly gives you precise numerical control over the click speed in milliseconds, as well as the pixel tolerance between clicks.

Step 1: Open the Registry Editor

1. Press Windows Key + R to open the Run dialog box.
2. Type regedit and press Enter or click OK.
3. If prompted by User Account Control (UAC), click Yes to grant administrator permissions.

Step 2: Navigate to the Mouse Registry Key

In the Registry Editor, use the left sidebar to navigate to the following path, or copy and paste it into the top address bar:

HKEY_CURRENT_USER\Control Panel\Mouse

Step 3: Identify and Modify the Values

Within the Mouse key, locate the following string values (REG_SZ) in the right-hand pane:

• DoubleClickSpeed: This controls the maximum time (in milliseconds) allowed between two clicks for the system to register a double-click.
  • Lower value (e.g., 200–300): Requires you to click much faster.
  • Higher value (e.g., 700–900): Allows more time between clicks.
  • Default: Typically set to 500 ms.
• DoubleClickWidth: Sets the horizontal area (in pixels) within which the mouse cursor must stay between the first and second click.
  • Increasing this value allows the mouse to move more horizontally without cancelling the double-click.
  • Default: Usually set to 4 pixels.
• DoubleClickHeight: Sets the vertical area (in pixels) within which the mouse cursor must stay between clicks.
  • Increasing this value allows the mouse to move more vertically without cancelling the double-click.
  • Default: Usually set to 4 pixels.

To edit any of these: 1. Double-click the name of the value you want to adjust. 2. In the Value data field, enter your desired number. 3. Click OK to save the change.

Step 4: Apply the Changes

Registry changes to mouse behavior do not always apply immediately. To enforce the new settings:

1. Sign out of your Windows user account and sign back in, or restart your computer.
2. Test your new double-click responsiveness by opening folders or shortcuts on your desktop. Repeat the steps above to fine-tune the numbers if necessary.
