Kill Multiple Processes From the Command Line
The first thing you’ll need to do is open up a command prompt, and then use the taskkill command with the following syntax:
taskkill /F /IM <processname.exe> /T
These parameters will forcibly kill any process matching the name of the executable that you specify. For instance, to kill all iexplore.exe processes, we’d use:
taskkill /F /IM iexplore.exe
Create an Icon to Force Kill All iexplore.exe Processes
Since we don’t really want to drop to the command prompt every single time we want to recycle Internet Explorer or Chrome, we can setup an icon to do the work for us.
