I can show some of the vital processes required in the Windows XP SP2. But some of these will only be running if you have additional service. For instance; IIS, networking, etc.

- system Idle Process

- system

- dllhost

- smss

- winlogon

- services

- svchost

- spoolsv

- explorer

- (Antivirus process) File may differ due to the product you use



The above is some basic set of list. But you may find some other REQUIRED processes too. That really depend on the softwares you are running.
