How to Reinstall Mouse.Drvby Jim Campbell
The "Mouse.drv" files are the drivers used to set up the mouse on a computer. Windows has mouse drivers on the system, so you typically don't need external drivers to set up a mouse. However, you may need to reinstall these drivers if the files are accidentally deleted or corrupted. You uninstall and reinstall a mouse driver to replace the "Mouse.drv" file, which is accomplished in Device Manager.
Click the Windows "Start" button and select "Control Panel" from the menu. Click "Hardware and Sound" and then click "Device Manager." This opens the configuration console.
Right-click the mouse in the list of hardware devices and select "Uninstall." Removing the device drivers only takes a few seconds.
Click the "Action" menu item at the top and click "Scan for hardware changes." The Windows operating system detects the mouse and reinstalls the "Mouse.drv" file on your computer.
