Hi hong.shen
When you launch Internet explorer it launches a iexplore.exe and a iexplore.exe *32, and as you add more browser tabs or windows, more iexplore.exe *32 process are started.
When I use the ""Utility - Enviroment"" action ""kill process"", all of the iexplore.exe processes are killed, both with and without *32.
But if you want to be certain that all processes named ""iexplore"" are killed, use a loop and use the ""Utility - General"" action ""Process Exist"", to query whether the process is still active, if yes, run it through the kill process action again.
Good luck.
BR,
Mustafa
