Tasklist.exe- Generic service name "svchost.exe"

Here is how to clarify the multiple entries for the process "svchost.exe" that occur. (Each has a different PID.) Service Host (svchost.exe) is a basic piece of the Windows XP OS that is involved with many low-level system services. These are placed in several service groups, all running under the generic service name "svchost.exe". To see which services are associated with each instance of svchost.exe, use the command tasklist /svc /fi "imagename eq svchost.exe"

Instead of using taskmanager, try Windows XP's tasklist.exe from the cmd line.
Examples- To see only the processes that use oleaut32.dll, enter tasklist /m oleaut32.dll

There are many more options and these are provided by switches. The full syntax is: TASKLIST [/S system [/U username [/P [password]]]] [/M [module] /SVC /V] [/FI filter] [/FO format] [/NH]
