You can review all the processes running into your system. So, go to control panel, administrative tools, services. Here you can disable all the services that you do not need according to the tasks you do with your PC. You must know what every service does in order to you disable it. If you donīt, search for information on the net, with google.
You can also, set in manual mode the service if you think that you will need it sometimes. If so, you can start it. The services in this mode do not use CPU while you do not use the programs that they require them.
Only allow run in mode automatic and started all the services that you require every time you work with your PC. If some day, something does not work, remember take a look with the services in order to you enable the respective service.
The point is that your operating system when starts up, just run the basic services in mode automatic or manual that it needs in order to it works for your needs.
You should see that CPU percentage goes down and your problem will not exist. Good luck.
P.S. I forgot to tell you, my operating system is Windows PRO XP SP 2, but Vista is the almost the same cat with another skin.
When you are idle, go to: http://download.cnet.com/Process-Tamer/3000-2094_4-10433612.html
I hope this tiny program will help you, it describes all data related with svchot services and even display if the service cam be paused or stopped.

Dear James
I was curious and googled it and came up with this excellent answer which received many compiments.There's no point in re-inventing the wheel, here is the site: http://www.howtogeek.com/howto/windows-vista/what-is-svchostexe-and-why-is-it-running/

Hi
I had the same problem some time ago on my XP machine.
It happen to be a VIRUS, a spy, worm or similar.
do run the BEST anti virus, anti mail... you can find.
(I purchased ESET)
2 weeks ago, on a slow PC, with a 2Ghz dual core CPU, 3GB of RAM, which could not play audio files... I found about 75(!!!!) visuses .
Good Luc.
Eli,
PIE Multimedia.
Lee, I have the same problem with this at times. If someone can help please email me at mmouse53a@msn.com Thanks a bunch everyone.
ORIGINAL QUESTION: Hi, I am most frustrated by a process that takes the CPU to 100 percent use and then lets it drop back to about 50 percent every couple of seconds, which seems to run while my Vista 32BIT computer is idle with no programs actually running other than Windows. The usage report shows the offending "thing" to be "svchost," whatever that is-but it can hog up to 78 percent of the CPU, making everything else run like it was an old 286! Can you please tell me what this process is? Is it something I can disable? How I can fix this very frustrating problem! Thank you.
Processors or CPU's can't sit around do nothing, or more precisely, when in use you can't selectively have some of the processor busy and the rest sitting idle waiting on you pressing the return key. svchost is a dummy application which keeps the idle bits of the cpu ticking over whilst it awaits the moment to real work. Obviously there's a fair amount of complexity going on in switching all this stuff around, but view svchost as a good thing (or a necessary eveil).
Obtain the program Process Explorer. It lists all working processes and you can arrange columns by increasing CPU usage, cycles, memory used, etc. When you detect the high CPU usage, quickly run Process Explorer, arrange by CPU usage and do a mouse-over of the offending svchost. That should tell you what svchost is, itself, running. The worst offender on my Vista PC is Windows Defender which I do have scheduled to run at noon every day.
Sorry I can't open all threats
, probably it has been solved.
I ever experienced the same case, and it's solved by simply disabling the automatic windows update.
Enabling or Disabling Automatic Windows Update
==============================================
Depending on your settings, Windows XP/Vista may routinely activate the Windows Update feature to scan for and download updates to Windows XP automatically. If you have a fast Internet connection, and usually don't remember to check for updates yourself, you'll probably want this feature turned on. However, if you already check for updates, and would rather not have your work interrupted, you'll probably want to disable automatic updating.
* To control or disable automatic updating, open the System icon in Control Panel (or right-click My Computer and select Properties), and choose the Automatic Updates tab.
* To check for updates manually, open Internet Explorer and select Windows Update from the Tools menu.
Note: even if you have enabled full automatic updating, Windows XP may only install critical updates. It's a good idea to check with Windows Update manually to make sure the updates you want are installed.
I had high mem usage with Firefox but tweaked it. Iobit Smart Ram let's me deep clean memory and automatically regulated mem usage. I'm at a %14 usage rate on average depending on what I'm doing on a HP DV1000
Sorry, not an answer, just that I am having the exact problem, but I use Windows XP. All this occured after I accepted the upgrade to Windows Live. Now I do not even have the possibility of removing that programme and the computer can only be turned off using the "end now" programme. Looking forward to receiving the solution.

Hi.... I had a similar problem with cpu showing 100% usage despite not having any file open. It seems the culprit was Nero 8 which had just recenbtly been installed on my computer so I uninstalled it and bingo, all now seems to be well. Regards DS
It seems I have the same problem. Helpers in the malware forums at Msoft and Castle Cops after analysis could only recommend 1) reformat my hard drive or 2) buy a new computer. BTW, neither Windows Task Manager nor What's Running can identify the culprit making svchost use up CPU time. When my modem is off, the CPU spikes to 20% every 25 seconds. Modem on, spikes to 60% every 5 seconds. Connected via DSL, 60-100% every 5 seconds. I think clearly malware. I have McAfee suite always updated which did not prevent this.
