Windows does not provide a setting for the physical pressure needed to press an external mouse’s right button; if light contact triggers it, test the mouse on another PC to determine whether its switch needs cleaning or replacement.
If this is an external mouse
- Test it on another computer.
- If the right button remains overly sensitive, the mouse itself is the likely problem. Check for dirt around the button; if cleaning does not help, replace or service the mouse.
- Microsoft similarly recommends testing a malfunctioning mouse on another PC and replacing it if it fails there too.^1^
- If it works normally on another computer, update its driver:
- Open Start, type Device Manager, and open it.
- Expand Mice and other pointing devices.
- Double-click the mouse, select Driver, and then Update Driver.
- Also search for Check for updates and install available Windows updates.^1^
- If the mouse manufacturer provides a configuration application, check it for button or debounce options. Standard Windows Mouse settings control such things as pointer speed, button assignment, and double-click speed—not physical right-button pressure.^2^
Changing double-click speed generally will not correct a right button that activates from one very light press.
If “mouse” means a laptop touchpad
Touchpads do have sensitivity and right-click gesture settings:
- Open Start → Settings → Bluetooth & devices → Touchpad.
- Expand Taps.
- Set Touchpad sensitivity to a lower level.
- If accidental context menus continue, turn off Tap with two fingers to right-click. You can retain physical right-click using Press the lower-right corner of the touchpad to right-click, or disable that option too if it is the trigger.^3^
If the problem disappears when the touchpad is disabled but returns when enabled, install the touchpad driver supplied for the exact laptop model by its manufacturer.
