windows 7 - difference between process explorer and task manager -

below screen capture of process explorer(left) , task manager(right) in windows 7. process list in task manager sorted pid. can see processes(csrss.exe, wininit.exe, services.exe...) missing in task manager window.

can explain why?

thank in advance.

by default, windows 7's task manager shows processes running under logged on user.

click on show processes users button below see system processes well.
