System Configuration Utility

I'm looking for a solution that unnecessary services running in the system.
This operating system is XP Pro Pack 3 and slow down very badly time to time. I checked with Task Manager for CPU usage.   There is high usage (98~99%) happening to one of SVCHOST.EXE.  I attached tasklist report.  I scanned with TDSSKILLER.EXE, but nothing found. I used MSCONFIG to deselect one service BITS for example, but comes right back on after reboot. Q1. How should I stop unnecessary service?  
Q2. Would some one take a look my attached tasklist report to give me suggestions?

I would disable following ones:

awhost32.exe                1676 awhost32
GhostStartService.exe       1716 GhostStartService
LMIGuardianSvc.exe          1776 LMIGuardianSvc
ramaint.exe                 1924 LMIMaint
LogMeIn.exe                 1944 LogMeIn
svchost is the issue as the asker reported.  Identifying the component within the svchost that is causing the higher CPU usage is all that is needed.  GhostStartService and LMI related components might be used to administer the systems Norton System works, and .
IMHO, advising someone to disable services that are components of various monitoring/management tools when they are not the ones that are causing the issue is leading the asker on a wrong path.

What applications are running on the system when the slowdown is seen?
Memory (low installed RAM) most likely will be the cause. i.e. applications have become more and more higher memory consumers.  While 1,2 GB  was fine before, now your system has Office 2007,2010 etc. Before when you had three word documents open and the system was fine (office XP/2003), now with the new version, your larger documents are slow to switch between document windows, etc.
Look at the taskmanager performance tab, is the memory   (PF usage close to the listed total for Physical Memory?)
If it is, the slow is because you have more applications open than the installed amount of RAM can support.  Your system is moving data from memory to disk when you see the slowdown while shifting from one application/document to another.) And from disk to memory to resume the session with the application/document you want to look at.

Let me correct myself, disable these for testing purposes to identify what is causing the issue, not to disable and leave it disabled forever.
