• Svchost.exe CPU / out max memory due to the update of Windows

  I'm having a problem with a svchost.exe process running the CPU at 100% and more than 200 000 K of memory.  The service seems to be related to Windows Update (PID 6408).  Is there any solution for this?

  Hi SF340_Driver,

  (1) you get an error message?
  (2) how did you get the information that the problem is related to Windows Update?

  Svchost.exe is a process on the computer that hosts, or contains, other individual services that Windows uses to perform various functions. For example, Windows Defender uses a service that is hosted by a svchost.exe process.

  See the link below

• Alert by file svchost.exe alerts for high performance, I also alerts for high disk writing & more

  When I'm on my computer, it's constantly noise and it has become very distracting and aggrevating. I'm afraid that this may cause problems with my computer as a whole. Could this be a virus? I have Norton 2011 and I use this program to the greatest extent, at least, I think I do. Any help in this area would be greatly appreciated. Sincerely, * address email is removed from the privacy *.

• Svchost.exe causing 100% cpu usage during the update of windows, even when disconnected.

  I recently had to re - install windows xp on a new hard drive for replacement. My version of xp home edition, SP2 OEM installation disc. (This is ith group included IE6)

  Once installed and running, could access windows update.

  Read all the threads associated etc. and installed SP3, disc after downloading microsoft on another pc. Installed after three trys, first two caused various mistakes, but third attempt seems OK!

  I've also updated the IE6 to IE8, as some sites obviously did not work properly with the older browser.

  Now go do the automatic updates, or log for manual updates... BUT!

  During the process, my cpu fan comes on fast and permanently! The CPU usage is showing that 100%, pc slows to crawl, the mouse becomes slow etc.

  This has never happened before on this machine before you reinstall clean, he had already automatically updated to SP3 and went very well, it was some time ago, before the failure of hard drive, and it has never had this problem!

  Only since having to do a cleaning manual update and re - install.

  The culprit seems to be svchost.exe, once it is used by the update, running the cpu at 100% and continues to do so EVEN after stopping the service, until I manually stop with the Task Manager!

  The svchost.exe instance showing a high is use: SYSTEM.

  According to the files of help here, it is a known issue and a fix KB927891 was issued for SP2, but this should NOT be necessary for SP3, and in fact difficulty used to perform anyway under SP3!

  Ideas for a guy to fix?

  I appreciate the support for XP runs out quickly, and after this update of windows will be redundant, but in the meantime it is always useful!

  Also if I turn off the automatic updates, how can I stop this annoying popup warning bubble?... I can't live without updating, but this bubble nag drives you nuts! :)

  OK just a update, now running cool and 100% auto update and manual update... How? I hear you ask...

  Well I had a beer and a reflection and came to the conclusion, it must be 'order' in which I updated the clean installation of XP.

  Origin, I loaded the old OEM disc new hard disk, loaded the drivers etc, then stop at windows update for updated files.

  Who told me my old incompatible browser and suggested an upgrade.

  I downloaded and installed IE8... still no joy, reading the forums comments I downloaded and installed SP3... which SEEMED to work, BUT then all the hassle of cpu to 100% with the automatic update and updated manual on the windows don't update site!

  So I just gritted my teeth, formatted the drive, another OEM of XP Home Edition SP2 installation loaded the drivers, installed a copy saved to SP3 and after restarting, THEN installed a saved copy of IE8 and THEN trotted off the coast to the windows update site... low and behold, it the connection without problem, did a search, and required updates appeared on the screen without delay all 123 of them...! :)

  Did the updates, restarted and everything was fine, updates automatic in market and left the machine, after about 30 minutes appears the yellow shield, and it downloads a couple more update files without problem.

  All this time I followed the via the Task Manager CPU usage and the strange spike waited 100% apartment, it was on average from 5 to 20%!...so a great improvement has this effect, by simply changing the order of the updates installed from the original! SP3 IE before IE8.

  May not work for all have to do a clean install because of the HD failed, but its worked for me, and I am once more a "happy bunny!

• Svchost.exe to 47 to 52% of CPU usage! ;-(

  For some strange reason, I have svchost.exe running at 47 to 52% cpu usage.  It's 6 380 to 6 444 K memory with the standard description of host for Windows process in the Task Manager.  User name is NETWORK SERVICE.  The system idle process is a 36% with 57 to 67% CPU usage.

  ANY ideas what it is?  I thought maybe would it be re-indexing, but it went on-and-on-and-on... ;-(

  I use McAfee AV on my chip 64-bit Vista Ultimate OS and Intel (Dell Inspiron, 500 GB HD, 4 GB of RAM; LED display).  Hard disk no is used, is nearly 80%.

  Last scan was clearly for the AV scan

  TIA

  To check what service to use the CPU in a svchost with Process Explorer:

  • Click on "Show details for all processes" in the menu "file".
  • Make a right-click the svchost that you are interested in
  • Click 'properties '.
  • Click on the tab 'son '.

  Doing this causes some recent versions of Process Explorer crash on my Vista system but the 15.12 version published yesterday (January 12) seems to be OK.

  The phenomenon of high processor by Dnscache usage has been reported elsewhere, for example,

  http://social.technet.Microsoft.com/forums/en-us/itprovistanetworking/thread/d2a2ad2d-A406-410C-9B7A-e22104fd2e2e/

  A possible cause is a large number of entries in the hosts file. Some security software (anti-spyware/ad blocking) can use this method to block malicious Web sites. You can reset the hosts on its default file using this fix it.

  http://support.Microsoft.com/kb/972034

  You can also try to flush the DNS cache:

  http://www.Vistax64.com/tutorials/74209-DNS-resolver-cache.html

  If it's not the hosts file, try to uninstall McAfee in the case which is in question.

  If you can't find what is the cause, running with disabled dnscache should not cause problems.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  How to install a device driver in Vista Device Manager

  If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
  Updates, that leaves about Windows updates but it will not install the drivers that will be generally
  older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
  get new manually if you wish.

  Hello

  You did changes to the computer before the show?

  Svchost.exe (Service, or SvcHost host) is a system process that hosts several Windows services. It is essential in the implementation of the process of the so-called service shared, where a number of services can share a process in order to reduce the consumption of resources.

  Sometimes viruses can usurp themselves as system files.

   

  Method 1: Put the computer to boot and see if that helps:

  A clean boot to check if startup item or services to third-party application is causing this issue.

  Reference: How to solve a problem by performing a clean boot in Windows Vista or Windows 7:

• Svchost.exe is SIGNIFICANTLY slow down my computer

  Hello, I recently went on vacation last week and a half before hand, I shut down my computer, so there are no memory leaks for my era [6 days].  I came home and turned on the computer which ran fine for awhile.  But then my computer started to act, because every once and a while, but this lasted since I got home.  Norton is my anti-virus and continues to tell me that "svchost.exe" using a lot of memory.  I must have at least 15 + svchost.exe process open for what reason so ever.  3 of which are in high use [one to 70,000] and the second at 20,000 and the other 10,000.  The first two [70 000 and 20,000] are both in the category of user name of the 'system' and the third one [10 000] is in the category of user name "Local Service".  I need help to solve this.

  I was wondering if it could be a virus/Trojan horse that has affected the svchost.exe program?
