One day, i have trouble to use my pc. Yes, there is windows 7 installed there. I have no idea when the firefox stuck, and my task manager unresponsive to kill the process.
But I find something good. I try to kill process from the command line.
i read the source from the link below. And of course you can try it .
To kill any particular process use the Taskkill command. For example to kill Firefox, run the command as:
Taskkill /IM firefox.exe /F
