Mouse not working on Windows 11
A mouse that won't click, scroll, or move on Windows 11 is usually a connection, battery, or button-switch issue. Run through these, then test every button live.
Step-by-step fix
-
Replug the USB receiver (try another port) or re-pair Bluetooth; replace the battery on a wireless mouse.
-
Run the CheckMyMic mouse test — check left, right, middle, scroll and a double-click.
-
Clean the optical sensor and try a different surface or mousepad.
-
Adjust pointer speed and double-click settings in Windows 11 mouse settings.
-
Update the mouse/USB driver and restart Windows 11.
Frequently asked questions
My double-click registers as one click on Windows 11.
That's usually a worn button switch. Run the mouse test's double-click check a few times — if it's inconsistent, the switch is failing. As a stopgap, lengthening the double-click speed/window in Windows 11's mouse settings can buy the switch some time.
The scroll wheel doesn't work on Windows 11.
Open the mouse test and scroll over the pad. If nothing registers there, the wheel encoder is faulty; if it does register, the wheel is fine — check the scroll settings in Windows 11 and the app where scrolling misbehaves.
The mouse still misbehaves on Windows 11 after every step — now what?
Test the same mouse on another computer with the CheckMyMic mouse test. If the fault follows the mouse — a button that won't register, phantom double-clicks, dead scroll — the switch or encoder is worn and it's replacement time. If the mouse behaves elsewhere, the problem is this machine's port, driver or settings.
Should I turn off "Enhance pointer precision" on Windows 11?
It's mouse acceleration: the pointer moves further when you move faster, which feels inconsistent for gaming and precise work. Find it under Settings → Bluetooth & devices → Mouse → Additional mouse settings → Pointer Options. If the pointer moves erratically regardless, that's the sensor or surface, not this setting.
