Update your Mouse Drivers
Reinstalling the drivers only fixes or repairs the corrupt drivers. It rarely provides you with the latest update for the outdated drivers. If you want the most recent driver updates for your device then either you need to check the device manufacturer site or go for a dedicated driver tool.
