This issue can occur if your computer uses Advanced Configuration and Power Interface (ACPI) power management. If it does, updating the mouse driver can cause the mouse to stop responding. Changing the mouse driver causes the first driver to unload, but the new driver does not automatically assume control of the mouse. Although the driver normally acknowledges hardware changes, because the hardware is not physically changing with the update, the driver will not "see" the mouse until after you reboot to initialize the driver and hardware together.
To work around this issue, press ENTER twice to complete the driver installation and permit your computer to restart.
