Earlier this year, I talked about configuring the macOS to automatically disable the trackpad when a mouse is connected to the MacBook. This feature comes in handy for those users who always use a mouse and don’t want to use the built-in trackpad after connecting the mouse. In Windows operating system, a graphical option to automatically turn off the touchpad when a mouse is connected can be found under Mouse Properties in Control Panel. In addition to that, if you’re running Windows 10, you can now configure it to automatically turn off the touchpad when a mouse is connected to your netbook or notebook right from the Settings app. If you’re using a notebook or netbook equipped with ELAN or Synaptics touchpad, an option labeled Disable internal pointing device when a mouse is connected should appear under Mouse Properties. The following are the steps you need to follow in order to automatically disable touchpad when a mouse is connected in Windows 10, 8/8.1 and Windows 7. Disable touchpad when a mouse is connected in Windows Method 1 of 4 For Windows 10 Step 1: Open Settings, click Devices icon, and then click Mouse & touchpad. Step 2: Under the Touchpad section, turn off the option labeled Leave touchpad on when a mouse is connected. Please note that the option might not appear in non-precision touchpads. Refer to our how to enable the precision touchpad on any Windows 10 laptop guide for more information. Method 2 of 4 (This method should work fine on Windows 10, Windows 7, and Windows 8/8.1) Step 1: Open the Control Panel by navigating to the Start menu and then clicking Control Panel. Step 2: Change the default View to Small icons. Look for the entry named Mouse and click on the same to open Mouse Properties. Step 3: Switch to the ELAN or Device Settings tab and look for an option titled Disable when external USB pointing device plug in or Disable internal pointing device when external USB pointing device is attached.

Finally, change its value to 33 (make sure that Hexdecimal is selected under Base section).
