Windows XP Pro only-
Svchost.exe was created to check the services that must run each time the system is started. Svchost.exe is located here:
%SystemRoot%\System32 folder
It is common for multiple instances of Svchost.exe to be running at the same time. This happens because Windows will allow Svchost.exe to be started at multiple times per session. Each Scvhost group can contain separate services. This grouping of services allows for much better control and for a simpler debugging process.
If you would like to view the services that are running in each Svchost process, here's how:
1. Go to Start>> Run. Type in:cmd [Enter] or click OK.
2. At the command prompt type in: tasklist /svc >c:\taskList.txt
Note: Copy and paste the above command for better accuracy.
