SVCHOST taking up CPU

For the in depth answer check out the link. http://www.howtogeek.com/howto/windows-vista/what-is-svchostexe-and-why-is-it-running/ The short version is svchost runs DLLs which are your programs such as spy ware protection and any other start up program. You have to many programs running at once which in turn eats up CPU use.
A simple way to remove them from the start up process is to use a freeware registry editing program called Quick StartUp. You can turn the ones off you don't need or turn them back on again if you change your mine. The link to get the program is http://download.cnet.com/Quick-Startup/3000-2344_4-76051.html?tag=mncol

SVCHOST usage

I have seen that as well. I use the Process Explorer to watch my CPU usage as I use the laptop. I find that the same thing happens when the computer encounters a problem and is sending an error message to MS or HP about there program or printer. I prove it by suspending the operation and see if the CPU drops to normal. If it does, I kill the process if I think it is not important enough to send the report. If it is an update for Symantec or a live update for Windows, I let it finish and then go back to what I was doing on the computer before the SVCHOST program started. That takes care of that problem for me.

I had the same problem on my computer and when I killed the process using the task manager, it would stop the CPU hogging. I found that it was McAfee, the anti-virus program that was causing my problem and when I eliminated the anti-virus program and went to another, my problem was no longer with me.
If you need any further information about this from me please let me know.

This Should DO IT for UUU

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...

CPU usage

I have a similar problem, in that my CPU runs at 90-100% at times, yet when I look at the processes in Task Manager, I can't find the program that is hogging my computer. When I add up the CPU times the active processes use they don't come anywhere near 100%, yet Tas Manager shows very high CPU use.
I have the following configuration:
Toshiba Satellite laptop
Intel Core2 CPU
2 GB memory
Vista Home Premium 32bit OS
Any help/suggestion is appreciated.
(NT) Please start another thread for your question. Thank you!

100% CPU usage
by Charlie Brown 10 - 4/26/09 1:34 PM In reply to: CPU usage by fmerczI had this problem (up to 75 & 80% usage) until today. When I was searching for antispyware, I realized that MalwareBytes Antimalware was doing the same thing as SpywareFighter and was much better rated. I removed SpywareFighter and guess what ? My CPU usage has dropped to 0 - 10% and my computer response is way faster.
What is svchost
by Nelson Vega - 4/17/09 9:34 PM 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.

THEN GO TO NEXT URL I POSTED- WILL HELP YOU FIX (FIX) YOUR PROBLEM- HOW TO FIND OUT AND GO TO THE SERVICES THAT REQUIRE MORE SCVHOSTS. THE MORE SERVICES YOU 'TURN OFF' THE FEWER SCVHOSTS you will require, meaning the fewer CPU's your PC will use.

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?
by tedsworld - 4/17/09 11:19 PM In reply to: 100 percent CPU usage caused by SVCHOST process, need help by Lee Koo (ADMIN)
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......
Ouch! This ones a pickle

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.
You can do as suggested:
Restart SVCHOST it in task manager. (See above for instructions)
Run your virus scans.
You might also:
Check "event viewer" for possible causes. Tell us what you find here.
Run a "startup repair".
http://windowshelp.microsoft.com/Windows/en-US/Help/5c59f8c1-b0d1-4f1a-af55-74f3922f3f351033.mspx
Check the CVS files for corrupt files to confirm they are there. Check near the bottom of this very long file for corrupt files. Cut and paste what you find there, here. We do not need the entire file. Bottom 40 lines should do.
If the event viewer fails to identify the problem and these options fail then you reboot/re-install your OS. Corrupt file in OS. Sorry.
bogus answer

===========
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.
