Googlade lite snabbt, du har säkert redan sett detta då det kom upp som första förslag, men ifall!
"Plug the mouse in, go to control panel, click "mouse", select the hardware tab, you should see a device with a name like USB mouse, click on it, hit the properties button, under the driver tab there should be an uninstall button, click it (if it is greyed out, go to the general tab, and click "change settings" first), after the mouse is uninstalled unplug your mouse and plug it back in ( for best results, you should be connected to the internet). Windows should reinstall your mouse automatically!"
Har du testat det?
