Systemprocesses (like Windows Firewall) cannot be identified in Tasklist or Taskmanager
Some of Windows services run under "svchost.exe"
Use command TASKLIST in a command shell. Without parameter it delivers a Tasklist similar to the list of processes under Taskmanager (example 1).
While names like cmd.exe or perl.exe are obvious, others need to be known (spoolsv.exe - spooler service, csrss.exe - Client Server Runtime).
For finding the process ID (PID) of a certain service, you might need to know it's original servicename, for instance "SharedAccess" is the servicename for the displayname "Windows Firewall/Shared Internet Access". It can be looked up in the properties of the process in services management Console.
Use TASKLIST /SVC in order to view the services belonging to a (svchost-) process:
svchost.exe 924 DcomLaunch, TermService
svchost.exe 992 RpcSs
svchost.exe 1100 AudioSrv, Browser, CryptSvc, Dhcp, dmserver,
ERSvc, EventSystem, helpsvc, lanmanserver,
lanmanworkstation, Netman, Nla, RasMan,
Schedule, seclogon, SENS, SharedAccess,
ShellHWDetection, srservice, Themes, TrkWks,
W32Time, winmgmt, wuauserv, WZCSVC
svchost.exe 1156 Dnscache...
and voilà, there they are (above example of Windows Firewall runs as "Shared Access" under PID 1100).
