To do this, press Windows + R, type main.cpl, and hit Enter. Go to the Buttons tab > Button configuration. Check the box to make the right button primary. Uncheck the box to keep the left button as primary. This is the default setting. Click OK to apply. Method 3: Change the primary mouse button via Registry Editor For more advanced customization, you can modify the mouse button settings through Registry Editor. This is perfect for managing multiple devices. Open the Registry Editor by pressing Windows + R, typing regedit, and pressing Enter. Navigate to the following path. On the right pane, double-click the SwapMouseButton REG_SZ value. Set the value to: 0 to keep the left mouse button as the primary button or 1 to make the right mouse button the primary button Click OK, then sign out and back in, or restart the computer to apply the change.
