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 at its scroll pad and look at the recent browser wheel events. If no event registers there, check Windows 11's scroll settings, browser settings or extensions, and another browser or computer before concluding the encoder is faulty; an event proves the browser received input, but it cannot prove the physical wheel is healthy.
The mouse still misbehaves on Windows 11 after every step — now what?
Test the same mouse on another computer with the CheckMyMic mouse test. Compare the recent browser wheel-event pattern as a clue, remembering that OS/browser settings and event batching can change what the page receives. A fault that follows the mouse across systems is stronger hardware evidence; behavior that disappears elsewhere points back to 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.
