This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Does it actually say System.exe or just System? What PID does this process have? –  grawity Mar 1 '12 at 13:09
Is System, and it has PID 4 –  user117177 Mar 1 '12 at 14:23
PID 4 represents the Windows NT kernel, not a userspace process. High CPU use might be caused by a buggy device driver. –  grawity Mar 1 '12 at 15:23
As this is a different OS version (Win 8 and Win Server 2008 aren't the same) @GrahamWager I'm not so sure this is a dupe. –  KronoS Feb 4 '13 at 18:59

Check out Process Explorer from Microsoft Technet. It reveals a welath of information on a process and associated DLLs

I have done it but the subproccess of System doesn´t use any resources of CPU. it seems that Thread that consumes CPU is ntoskrnl.exe. This has a solution? –  user117177 Mar 1 '12 at 14:27
