I run Linux, normally I can shut down a process or application by just bringing up the Task Manager and shutting down the application. Most often it is Firefox being slammed by some script. That browser runs off a data base.
If the machine still says it is busy, I just pull the network cable.
Very very seldom do I have to reboot. Almost never.
It is not like that with Windows.
What task manager are you talking about? I ran “sudo killall firefox”.
