Default Behavior

Mouse Class Driver is a kernel device driver. In Windows 7 it won't be started if the user doesn't start it. If Mouse Class Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the mouclass service is not running because of the error.

Restore Default Startup Configuration for Mouse Class Driver

2. Save the Win7_mouclass_Service_Startup.cmd file to a local storage device.

The mouclass service is using the mouclass.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
