cannot end proccesses no matter what i try

Hello, i cannot end frozen processes via task manager. i press end process and then nothing happens. this happens to a bunch of different programs once in a while but mostly it happens to my itunes. can anyone help me? thank you

Download the PsKill utility from here:

http://download.sysinternals.com/Files/PsTools.zip

Unzip the package and copy pskill.exe to C:\WINDOWS\system32.

Right click the taskbar then select Task Manager. Go to Processes tab and look for the hang process PID. If PID column doesn’t not exist, go to View -> Select Columns, tick PID (Process Identifier). Write down the PID value.

Open command prompt by going to Start >> Run, type cmd >> enter.

Type pskill, space and followed by the PID value. For example, if the PID is 9596, then type pskill 9596 and press enter. The process will be terminated without affecting other running processes.

sweet.. thank you very much
