If you want to kill the processes after they start up, put this into a batch file:
taskill /f /t /im "[the process name]"
taskill /f /t /im "[the process name]"
etc. etc.
If you want these to be removed from the startup consistently, make a VB script run at startup that deletes the unwanted programs from the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\.
