Is there a service responsible for controling the mouse? I want to try stop/starting it after making a few control panel changes via the registry.
(I need to get the changes to apply witout rebooting because rebooting just resets them back to default)
The mouse isn't controlled by a service. Its function is managed by a device driver. See the registry key HKLM\SYSTEM\CurrentControlSet\services\mouhid. If you run DRIVERQUERY.EXE, you'll see that it runs as part of the kernel and doesn't have its own process id. As such, I'd doubt that it can be stopped or killed.
As noted by BillP3rd, mice are handled by a kernel driver, not by a service.
However, drivers are too managed by the Service Controller and can be controlled by sc or net start.
(sc stop beep to kill the PC speaker is a classic.)
