I run Task Manager all the time. It’s always minimized in my tray. But sometimes the list of processes doesn’t give enough info. Take for example the 4 svchost.exe processes. What are they doing? Well, with XPSP2, you can now do the following command line and get what service own the process:
c:>tasklist /svc /fo table
Neat!
