Svchost.exe is causing cpu at 100% of capacity

• Windows XP I often setup.exe keeping the CPU at 100% for at least a few minutes.

  Running Windows XP, I often setup.exe keeping the CPU at 100% for at least a few minutes... this process can be completed or ignored?

  "Setup.exe" is a generic term used by many applications.  The short answer is 'yes', it's OK to complete the process, but you really need to know what it is and why it continues to run.

  You probably need to download, install, update and run these free malware scanner (not at the same time):
  MalwareBytes AntiMalware
  SUPERAntiSpyware

  If that is not fix things, and assuming that this process begins when you start the computer, download, install, and run Autoruns.  When Autoruns has finished scanning, click the 'Connection' tab and look for the line that contains "setup.exe".  You can just uncheck the box on the left, or remove the item, which will prevent the routine of starting when Windows starts.

  Preferably, however, you should look at the path containing setup.exe where you should be able to deduce what application is trying to set itself up.  You can then take the appropriate measures, which may be simply delete the folder that contains the file.  Note that if you delete the file, you must ALSO remove the line in Autoruns, otherwise you will get a "file not found" error every time Windows starts.

• Why my svchost.exe process constantly runs at 100% CPU usage?

  Recently, my computer was extremely slow.  I thought that was the cause of a worm or virus but after I used Norton to take care of that my system is still slow right too. When I checked my system process, its display svchost.exe using a massive amount of memory. Therefore, my CPU usage is constantly at 100%.  Is it still the result of a bug? Or do I have to look elsewhere as the source of the problem? Thank you

  It is possible that a recent update of Norton was faulty or caused one conflict with another program on the PC.

  Activity excessive svchost.exe is often linked to one of the following:

  1 resource hog like Norton or McAfee (sad but true)

  2 be linked in Microsoft Update instead of Windows Update

  3. after having been updated for Windows Search 4.0 and its endless reindexing

  4. the presence of malware

  Unless you have uninstalled Norton AND used their removal tool, I doubt you really deleted ALL occurrences of Norton!

  FWIW, I helped a neighbor recently with his performance problem. The culprit in his case was Windws Search 4.0. And since there is no entry in the Control Panel Add / Remove programs to KB940157, I needed to follow the instructions offered by Nepatsfan here:

  Hi done as recommended, it was "hpslpsvc" - count must be a service of HP, I am correct?

  Yes, it's the "HP Network Device Support" service.  If you use Google to hpslpsvc, you will find a large number of complaints and a few corrections proposed at HP.

  See, for example, this long thread: http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1286890571088+28353475&threadId=1177917 buried in this thread are information that leads to this RESUME "critical update": http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=mp-65961-4&lc=en&dlc=en&cc=us&lang=en&os=228&product=2512010

  There are also the following thread, which proposed adding hpslpsvc as an exception in Windows Firewall:http://h30434.www3.hp.com/t5/Printer-networking-and-wireless/Printer-driver-problem-on-HP-Photosmart-C6280/m-p/839

  From what I can tell, before the HP patch is available, two procedures most likely to solve the problem we have set the "Startup type" HP Network Device support on 'manual' and configure your HP device to use a static IP address.  So... try the HP update.  If that does not work, follow these steps (or add Firewall exception):

  To make the startup type of the service manual

  1. Start > run > services.msc > OK
  2. find HP Network Device Support, and double-click
  3. Set on "manual" Startup type (or you can try "disabled" and see if it causes other problems)
  4. Stop the service runs
  5. OK your way out

  To use static IP addresses (which is a good idea in any case).

  A. printer setup

  Using the controls on the front panel of the printer or the printer's built-in web server, configure the printer to use a manual IP address located in the subnet used by your router, but outside the range of IP addresses used by the DHCP server on your router.  Set the subnet, default gateway and DNS servers also.  (If you don't know what this means, or how do, after return with the brand and model of your router and your printer model.)  Repeat for each HP printer on a network, using a different IP address for each.

  B. configure ports

  1. Open Printers and faxes
  2. Right-click on the icon for the printer HP connected to the network
  3. Click on properties
  4. Click Ports tab
  5. Click "Configure Port"
  6. In the "Type the name of printer or IP address" box, enter the IP address that you set for the printer part A.
  7. OK your way out.
  8. Repeat for all printers HP connected to the network.

  Note that if your HP network device has been installed using the default 'HP standard TCP/IP"port you will notice on the Port configuration tab there is a box to check always 'print to this device, even if its IP address changes.' This box is not on the standard TCP/IP Windows port, and it's hpslpsvc who is responsible to control the IP address of the device to help Windows can find the device if IP address changes)

• Portege will extinguish after iTunesphotoprocessor.exe gets the CPU to 100% usage

  Hi all

  I am having a problem with my Toshiba Portege and sync with my iPad2.

  I'm syncing large amount of photos to my iPad, when synchronization progess is at the stage of optimization photos iTunes runs two processes iTunesphotoprocessor.exe and the CPU usage is 100%.

  The Toshiba fan then runs at full speed until the immedialtey of the computer turns off.
  It is not a normal shutdown of Windows 7 64-bit. It's an energetic power loss, while the Toshiba is on a/c.

  I can reproduce the same with my iPhone 4.

  I thought I should use a USB hub with an adapter separated instead, unfortunately, there is no difference.

  It is not only synchronize photos that it occurs also when I sync movies and only iTunes.exe running at 100% CPU usage.
  Which brings me to the conclusion that the iPad draws a lot of power of the Toshiba until the laptop is on its knees.

  I use external drives (not USB powered) and can copy a lot of data without any problem.

  Perhaps worth mentioning that I have improved the Toshiba two months ago for Windows 7 64 bit and installed all the 64-bit drivers found here on the forum with the upgrade of the BIOS.

  Any hint is appreciated.

  Thank you

  Hello

  In my opinion this has nothing to do with the power supply or the power adapter plugged.
  The iTunesphotoprocessor.exe belongs to the iTunes software and in my opinion this software highlights the laptop CPU s that cause automatic shutdown!

  This means that it is not a problem of laptop but the Apple software.
  I m not sure if it s a compatibility issue with 64-bit Windows system, but he s certainly an iTunes problem

  So, in my opinion, you need to reinstall this software to see if that would help
  You can uninstall this software from the system and could clean the registry with CCleaner, it helps to clean the registry
  After that and after new restarts, you can try to install a version compatible 64-bit iTunes maybe it helps

• (fontcache) Svchost.exe using 99% cpu

  Hi, I'm running Windows 7 Ultimate x 64. Randomly, the svchost.exe (fontcache) service will start using 99% of my cpu, everything a lot. Specifically, it starts happening when I play Team Fortress 2, but it also happens while I play the game. During a match, making the game lag, giving me a very large ping 2000ms + and no fps. If I end the process, it stops and is fine. But it could be the cause?

  Common programs, I have running at all times are as follows:

  AVG anti-virus

  Pidgin (AIM client)

  Skype

  Google chrome

  Windows media player

  Any help would be great, it becomes annoying random having my computer be bogged down for no reason. Let me know if you need more information

  Thank you, xJedix

  Hey guys, thanks for the suggestions.  Actually, I found another person who had this problem.  Their solution was to remove the additions of the shell that nvidia added to when you right-click on the desktop and things.  This has solved the problem, at least until now...  It's 3 days now without problem and also fixed my problem Explorer.exe crashing several times when I was reviewing the files :)

• After awhile java.exe is the CPU at 100%

  Hello!

  I have a problem with the java.exe in the environment in which I work. In the environment, I have a physical server: Sun Fire X 4100 Server with 2 processors and 16 GB of RAM for control of virtualization. On the system, this is the Microsoft Windows Server 2008 R2 Datacenter and vCenter 5.5.

  For the most part, we are 5 guys in the team who use the vSphere Web GUI. We are connecting to the server using RDP and after some time, we can not connect because the CPU is at 100%. It takes 20-30 minutes to be able to connect. And then 5-10 minutes to be able to click on something. For example, to kill the java.exe file keeps the CPU at 100%. This isn't a good idea because afterwords the Web GUI does not work so we need to restart the server.

  Anyone of you have any idea why this is happening?

  Sorry! I can't see the part about it being the physical server... which version of VC is this?

  The list file you most often is a process associated with Norton 360. However, malware is sometimes assumed the names of the legitimate files in order to deceive the end user. Norton is a Devourer of known system and as a result, I wouldn't be surprised to learn that he is a legitimate file in your case. However, I recommend you download, to update and scan with Malwarebytes and Superantispyware, just to be sure. If the scans do not detect the file and the problem persists I would contact Norton or remove Norton making sure to use the tool to uninstall do.

• Windows XP svchost.exe problems. Cannot find the latest updates for windows xp.

  Hello, this is my first time on the Microsoft Community page.

  I have a very strange problem with automatic updates svchost.exe and windows. I know that automatic update of windows, has been known to cause problems on XP and there is thus CPU utilization of memory leaks. Last night, I tried to install the latest windows XP updates, with automatic tool. The tool hanged during the process. Not sure why exactly. I never had a problem with it. I've been running Xp SP 3 for more than five years. In any case, I rebooted my system and checked to see if the updates actually treatment. They do not have. Then I went to the windowsupdate.microsoft site. I was trying to these updates. The scan never completed, he just constantly checked, for about 45 minutes. I decided to do some research. I found the C:\Windows\SoftwareDistribution folder "fix" online. He kicked, I renamed the file. And then disabled auto updates and restarted my computer. After windows starts, I re-activated automatic updates and waited. Nothing happened, so I did some research more. I noticed that svchost.exe uses about 25% the use of the processor. Normally my treated systemidle is 99%. I used Process explore and isolated the wuauclt.exe under the svchost.exe file. When I disable automatic updates executable, it is up to a full 99%.

  I'm not sure why it uses 25%, when I look at the actual use of the memory for the wuauclt.exe, it is only using about 17 k of memory. Which is quite low. I have not turned on microsoft update, starting in the configurations of parameters at windowsupdate. I know that in the past, that has been a problem and swallowed up system resources.

  Any advice would be helpful. Thank you in advance.

  There are a lot of threads on this forum - and many others - this problem - just try to do a Google search for UPDATES of XP SVCHOST - hits now more than 8 million.

  But to save you the trouble of tracking down the fix OK here is the short version

  1. disable automatic updates using Control Panel icon

  2. restart the computer - SVCHOST is now not going crazy

  3. check which version of Internet Explorer you have installed IE8, IE7 or IE6

  4. download and install - the links below - the good update for Internet Explorer.

  Assuming you have Windows XP 32 bits here are the direct download links:

  IE8: IE8-WindowsXP-KB2898785 - x 86 - ENU.exe
  http://www.Microsoft.com/en-US/Download/details.aspx?ID=41404

  IE7: IE7-WindowsXP-KB2898785 - x 86 - ENU.exe
  http://www.Microsoft.com/en-US/Download/details.aspx?ID=41442

  IE6: WindowsXP-KB2898785 - x 86 - ENU.exe
  http://www.Microsoft.com/en-US/Download/details.aspx?ID=41458

  5. Once installed, you can reactivate the automatic updates and using Windows Update.

  Note: The bug also affects access via Windows/Microsoft Update Web site.

  KB2898785 is the "Cumulative Security Update for Internet Explorer" (December 10, 2013)

  There is a bug in the function of automatic update under XP running the SVCHOST process at full CPU load (100% or 50% or 25% depending on the number of CPU cores you have). If you have a Quad core CPU the bug works the CPU at 25% (a carrot out of four) and eventually battles through a conclusion - but if your computer is a single old Celeron or Pentium bug works the CPU chip at 100% load for many, many h/solid.

  Faster your processor and RAM than you seem to make a radical difference to the actual times are waiting for you maybe search for updates complete. Most of the old core systems were never designed to deal with this kind of situation and can easily overheat. This is especially true of laptops and desktop systems older where the radiator can be partially blocked with fluff and hairs of animals - which could cause blockages or stops!

  Microsoft said last month that the updates of Internet Explorer are treated differently from all the other updates - which is originally the XP update engine run so slowly as to appear frozen. If the update service finds that you don't have the latest version of IE that is currently available, it starts to search the entire tree of updates of IE to see what it takes - rather than offering just the cumulative current update for your system.

  But if you manually install the update yourself update Internet Explorer service is fully updated and is not search for updates of IE. But until Ms. fix it will still occur whenever a new update is published.

  MS said that intend to prune the IE updates database so that only the main cumulative updates have been offered when a search has been launched - it did not in time for the update as it should of November and obviously has not arrived or worked either in time for the December Update!

  MS say they hope to have a fix before the January updates are released (Patch Tuesday) - that the problem will be activated once the next update Cumulative of IE is released.

  Three main points:

  1. 91 processes can be a little more that some people, but it is not an unusual or unacceptable number.

  2. I strongly recommend * against * trying to improve performance by disabling the process. IFT is very difficult to know what it is safe to do so, and for most people, it is more likely to cause problems to fix in the / and even if you're lucky and don't cause any trouble, your performance will likely get no better.

  3. it is difficult to know for sure what your problem is, but your description of it makes it sound like it is most likely that you are infected with malware. What anti-virus and anti-spyware programs do you run?

• 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!

  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:

  http://support.Microsoft.com/kb/929135

  Note: when you're done to diagnose, follow step 7 in the article to start on normal startup.

  Method 2: Read the following article to download and install Windows Defender in offline mode
