Windows Vista: 100 percent CPU usage caused by SVCHOST process, need help

This Should DO IT for UUU

In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN) 

Yeah, me too, wondering about the ever growing number of svchost.exe.'s on mu PC. I AM not a Geek, but do jump onto my taskmanager several times daily. I do end many active programs if I know I won't be using them for the day- and am getting quite good at knowing which ones to leave untouched. Now that is/was always accomplished the Hard way. Trial and Error- my least favorite learning mode- as in touching the bottom of a cast iron skillet, asking yourself: is it hot yet? is it hot yet?
AND, I noticed their number grows over time?? I recall, when my Sony Vaio rg44b was brand new some 2.5 years back. I think I then had only 4 instances running. I now have NINE (9) separate SVCHOST.exe's running on my PC. 4 are 'System', 3 are 'Local', and 2 are'NETWORK'. The biggest 1, a 'System', takes up some 32,800k memory. Unlike yours, none seem to take up many CPUs. I alphabatized the list of programs and counted from the bottom. 2 were right next to bottom, all but one were in the last 30 or so, and 1 usually stayed in the top 40, but never cracks the top 20. Re-Read that if you must, but it's there.
What I did was...

What is svchost

In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN) 

According to Microsoft: "svchost.exe is a generic host process name for services that run from dynamic-link libraries"
svchost is an executable file used by Microsoft to launch dll files. Why? because of the change in architecture away from Internal windows services and to a more manageable and secure mode of operation by not using .exe file (executable) to using dll (data link library) in this way if one program goes down it will not take down the whole OS. The problem with using dll is that you can't launch them, you need an .exe file to launch them; that's where the svchost.exe come in to play.
You can examen what's being run but it by using a dos window (command window) in both Vist and XP by typing tasklist /SVC. However it does not give you a view that normal users could read. In Vista simply double click the scv your interested in and will show you more readable information.

I,too,have been dealing with this problem. I am starting to suspect this may be an inherent glitch w/ Vista OS. Occasionally, my CPU will peg out to 100% and stay there--the only thing I have found that tones it down is to run a Ccleaner scan. Any help on this front would certainly be appreciated.

Windows Vista Question of the week?

The reason why your process are running so hard is because the windows VISTA IS FULLY AUTO AND IT TAKE UP A LOT OF CPU USSAGE
AND SO ON That's what windows Vista has as a down fall,
When they say it is a better system they were right but they didn't tell you that it takes up a lot of your resorses......

bogus answer

"More then likely you will be reinstalling your OS from scratch very soon. Why? Because it's broken. You have a corrupt file in SVCHOST."

===========

NONSENSE. Everybody at some time or another has problems with SVCHOST. And their OS is not "broken". It's the application driver behind that instance of SVCHOST that is broken. I've seen it caused by printers, and bloated antivirus modules like Norton and McAfee.

You download Process Explorer (free tool by Microsoft) and see what is BEHIND the SVCHOST, that is causing that instance to run all the time.

it's normal to have 5 or 6 SVCHOSTs running, for different reasons. But if one is hogging the CPU, then you use something like Process Explorer to investigate and stop the problem.

A lot of people are suggesting using task manager and that will work some, but Process Explorer is like Super Task Manager. Microsoft should include it with every copy of Windows. I don't know why they don't.
