Hello. I had a problem with svchost.exe hogging my cpu a few months ago. It was easily fixed by downloading the latest updates for my computer. Now, just a couple of minutes after booting up, the svchost proccess is back! I read on the internet about disabling automaic updates would help, but it didn't do a thing!

 

I'm really confused on what to do. I could barely access this site and write this here post. :(

 

Oh and my computer is Windows XP with service pack 3, and if it matters I have 1GB of RAM

If you open the Task Manager and click on the Processes tab and scroll down to the svchost.exe you will see a number of these. 

 

To determine which service is causing the problem you can perform a Clean Boot.

 

How to perform a clean boot
 
***This is a diagnotic tool for Windows Vista, Windows 7, and Windows 8.  This will not repair your computer, but it may point to where the problem lies so that a repair can be made.***
 
Warning:  Disabling items in Services or Startup may leave your anitivius disabled until the process is ended.  For this reason I would suggest that you perform this process off line.
 
(1)  Click on the Start orb startorb_zps06e1f985.png, then type msconfig.exe in the Search programs and files box.  
 
(2)  When msconfig is seen in the pane above the search box and under Programs, right click on it, then click on Run as administrator.
 
msconfig2_zps2e854ee3.png
 
If you are prompted for an administrator password or for confirmation, you should enter the password or provide confirmation. 
 
(1)  Click on the General tab.   
 
(2)  Click the Selective startup option. 
 
(3)  Remove the check mark in the Load startup items  check box. 
 
Cleanboot_zps3b042516.png
 
(1)  Click on the Services tab. 
 
(2)  Place a check mark in the Hide all Microsoft services check box, this will remove the Microsoft Services from the list but will still be running. 
 
(3)  Click Disable all, this will remove all of the check marks in the Services list, then click on Restart.
 
Caution:  By disabling the Services your antivirus will not be active, for this reason I suggest that this process not be run while online.

If the problem does not reoccur after the reboot continue with the process of elemination to find the Service which is causing this in Option A.  If the problem does reoccur after the reboot go to Option B.
 
Option A
 
**The following is a process of elimination to find the Service or Startup item that is causing your problem**.  
 
*  If the problem does not reoccur after the restart go back to Services and place check marks in half of the boxes and restart the computer.  
 
*  If the problem still does not continue return to Services and remove the check marks that were added, then place check marks in the remaining half of the boxes and restart the computer.
 
If the problem resumes after a restart in one of these halves, you will procede with this process in the half where the problem occurs.  If this does not continue in either half you should repeat this process in Sartup
 
*  In the half of the Services that the problem is found, remove one check mark at a time and restart the computer to see if that  is the Service causing the problem.  Continue to do this with the Services untill the service causing this problem is  found.
 
Option B
 
Search Startup itmesIf the problem is not found in Services, remove all of the check marks, click on the Startup tab and repeat the search process there.
 
Caution:  If this is a laptop, make sure, you do NOT disable any keyboard, or touchpad entries.
 
If this problem is found, run the System Configuration Utility, then click on the check box to clear the item.
 
To open the System Configuration Utility:
 
(1) Click on the Start orb startorb_zps06e1f985.png.
 
(2)  Click on Control Panel
 
(3)  Click on Administrative Tools.  
 
(4)  Double click on System Configuration.
 
If the Service or Startup item is identified please include it in your next post. 
 
When you are finished, click on the General tab in System Configuration, then click on Normal Startup, click on OK, then restart your computer.

hi, maybe this is a possibe solution for your problem:

 

- close svchost.exe from task manager when running in high cpu usage

- run windows update ( from command line, start wupdmgr.exe, or launch it from start menu-programs)

- when ie opens, look for 'change settings' on the left side and select it

- on the right side at the bottom of the page, you'll see something about windows update and microsoft update

- select or unselect that option (I don't remember), the point is you should switch back to windows update

- you should see a message about reverted to windows update

- restart your xp
