you re-post this inquiry in either XP forum or the Office & productivity forum. Click on left "see all forums". Hopefully they can help define which tasks have you concerned.
You could also (?) copy & paste list to a notepad text for Googling each process individually for descriptions.
On the Task Manager's second tab, which is Task Procedure tab(i use XP Chinese version so the translation might be varied), on WinXP, there are a series of tasks(*.exe). I'm wandering i could know what they mean and how to deal with it respectively.
Like i use Security Task Manager(v1.7)and it tells me which one is highly insecure and so i could quarantine it...Is that right to do so?...
