Likely fix
Fix: Mouse double-clicking by itself
A mouse that double-clicks by itself is usually caused by a worn mouse switch, too-fast double-click settings, low battery, dirt, or mouse software settings.
Quick answer
Lower the double-click speed in mouse settings, replace or charge the battery, then test another mouse. If it still double-clicks on other devices, the switch is probably worn out.
Important warning
Unwanted double-clicking is often a hardware switch failure, especially on older heavily used mice.
Try this
- 1 Open mouse settings.
- 2 Lower the double-click speed.
- 3 If wireless, replace or charge the battery.
- 4 Clean around the mouse buttons gently.
- 5 Disable custom mouse software profiles temporarily.
- 6 Test the mouse on another device.
- 7 Try another mouse on the same computer.
- 8 Replace the mouse if it double-clicks on multiple devices.
Common causes
Worn mouse switch.
Double-click speed set too fast.
Low battery.
Mouse software profile issue.

What to check next
- Check whether it double-clicks on another computer.
- Check double-click speed settings.
- Check whether another mouse behaves normally.
- Check whether custom mouse software is installed.
