You press Ctrl-Shift-Escape to display the Task Manager and browse through all your tasks to see what’s slowing down your machine. Then there is this “svchost.exe” that shows up several times. Sometimes running the tasks as SYSTEM, NETWORK SERVICE or LOCAL SERVICE.
To find out what is running behind the svchost you can use the commandline tool “tasklist”.
Open a command prompt.
Type “tasklist /svc”, hit [Enter] and behold you can actually see what is running behind the svchost.exe.
