• 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.

• excessive use of svchost.exe memory

  Operating system Windows XP Home Edition SP3

  RAM 1 GB (just upgrade to 512 MB)

  Atitvirus Zone Alarm Firewall/antivirus Suite Secruity

  Internet - IE8 browser

  A classic computer session the process svchost.exe (System user), seen in the Windows Task Manager, will constantly increase its memory consumption until my computer slows to a crawl.  I've increased the RAM from 1 GB to compensate and now amseeing a much bigger memory usage by the process - up to 250 MB!  I tried to end the task and restart the bulk of the process svchost manages but have been unable to isolate the subtask that causes excessive memory consumption.  This has the advantage of reducing the consumption of RAM temporarily, but in half an hour or so consumption of memory is way up again.

  I repeatedly ran some virus scans by Zone Alarm (currently being updated), Malwarebytes "Anti-malware", "Search and Destroy" Spybot and SuperAntiSpyWare 4.9 nothing done.  I have IE8 configured to avoid pop ups and have blocked most of the cookies.

  What can I do to manage the svchost process to stop the runaway memory usage?

  Chaos_Edit,

  Of course, you were correct.  I downloaded the latest version of MS MSRT last Thursday (v 3.9.3901.0) and he discovered the Alureon virus.  He "partially" deleted and recommended I run a full scan using anti-virus software.  I ran my Checkpoint/Zone Alarm antivirus-Super-scan and it finally detected and quaranteed the virus.  Since then, my svchost.exe program slept about 25 MB memory usage.

  What intrigues me (or mind depending on my mood) is that this evidentlly virus exists since 2006 and still my anti-virus for Checkpoint/Zone Alarm, Malwaretytes Anti-Malware and SuperAntiSpyware all failed to find it.  I ran great/deep scans using the latest versions of each of these software products every night for the last month.  My ZA product is set to check and download updates every evening before the scan in depth.

  In addition, I started to download HitmanPro to discover that he wanted to maintain a direct link to my computer.  Probably not in my interest.

  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

  If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.
  Continue with the remaining steps to pin-point on the third party service.

  After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

• purpose of svchost.exe

  My system is bogged down, and Task Manager shows "svchost.exe" uses 95 + % of the processor.  What he does?  And is it possible to make it run in the background without stalling other tasks?

  It could be that your system is afflicted malicious software.  Sometimes malware will hide behind a svchost.exe process.
  Beginning troubleshooting first at least make an effort to eliminate the risk of malware, then fix any issue remains the scans by operating clean.
  It doesn't matter what you use for the removal and malware protection:
  Download, install, update and do a full scan with these free malware detection programs:
  Malwarebytes (MMFA): http://malwarebytes.org/
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
  They can be uninstalled later if you wish.
  If you still have questions the scans by operating clean, then to eliminate the questions and riddles, please provide additional information on your system.
  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..
  Click Start, run and enter in the box:
  Msinfo32
  Click OK and when the system info summary appears, click Edit, select all, copy and then paste the information here so that we can see some details about your system.
  There will be some personal information (such as the user name and the name of the system), and anything that turns information private for you, simply delete the pasted information.
  You may be able to get clues with what is happening with your svchost process using the Task Manager and maybe understand.

  You will always be able to understand what is happening with your svchost process if you use Process Explorer.

  Download Process Explorer, so you can see what is 'really' running on your system, especially behind those svchosts several process see you in the running task manager.

  Download Process Explorer from here:

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653.aspx

  You'll like Process Explorer when you get the hang of it.  Process Explorer is the Manager of Windows taskbar on steroids.

  Process Explorer installs nothing so it won't slow down your system since it works only on request.

  Process Explorer can seem a little intimidating at first because it has so much information, but you will begin to make love the way it works when you're looking for performance problems.   You can even say EP you want it to be your new default 'Task Manager' value in the future.  You can always run the original tasks as Manager.

  Once you get Process Explorer running, expand the columns, made drag the corners of the screen for it's largest, etc., so you can see as much information as possible in the window.  Now you can really see what is running on the system.

  Here's a screenshot of my poor system when I use Process Explorer:

  http://img222.imageshack.us/img222/2567/ProcessExplorer.PNG

  The CPU column is usually the most interesting start with performance issues - which uses the most
  ?
  It is OK and normal to have several svchost running processes.  Important XP Services are actually runs under the svchost process. There are sometimes an XP Service that runs under a svchost process, sometimes there are several Services in XP, which runs under the svchost process.
  Sometimes malware will hide behind a svchost process because the malware knows that you won't be able to find it in the Task Manager.  He will hide behind a svchost.exe process to deceive you, but you can outsmart it.
  Malicious software can disguise itself also seems to be a legitimate process of XP or he could hide under/behind other processes that you see running in Task Manager if you can't see the execution.
  The malware would trick you into thinking you must use a System Restore Point, run a repair install or reinstall your XP from scratch when you really don't.
  Looking at the display in process Explorer, you want the CPU most to be associated with the system idle process.  It's 'free time' on your system, so more time there, more free.
  If you look at the graphs of performance and see red spikes (or not) double click the graphic in the upper left corner to display the graph to use.  Move the mouse over any pics to see what are the causes.  Even if the Spike has already scroll screen, you can still move the mouse over the edge to see what caused.  You can also just wait for a pic to happen and then see what caused the Spike.
  To help understand your process svchost and what is running under them, read this article and you will be smarter than the average bear:
  http://www.bleepingcomputer.com/tutorials/tutorial129.html
  Then with a few Google searches, you can watch every thing running behind your svchost process and Process Explorer and see what it is and decide if your configuration needs it or not and then decide what to do about this.
  If you think you have a svchost.exe process amok, run using Process Explorer, you can right-click that offensive svchost, properties and on the Services tab and son, you can see which runs under it.
  There is a CPU column it will expand (make the wider column) so that you can see CPU.  Maybe you can spot what background process is so CPU consumption under the svchost.exe process.   Stroll under the svchost process and you will find the problem.
  You can also see what is running under each svchost simply by pointing your mouse on the svchost.exe process.  Some of them have just a things working under them and some will have several things (I hope that all the legitimate XP services) and some will have a lot of things.
  If you have a svchost process that is afflicted, which runs under your afflicted?
  No running process must defy reasonable explanation.
  First, see what you can find using Process Explorer, then if nothing is obvious, additional advice.

  Do, or do not. There is no test.

  Hello

  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.

  There may be multiple instances of svchost.exe running on your computer, each instance containing different services. One instance of svchost.exe can host a single service for a program, and another instance can host several services related to Windows. You can use Manager tasks to display services running under each instance of svchost.exe.

  To view the services that are running under svchost.exe:

  (a) open the Manager the tasks by right-clicking on the taskbar and then click Task Manager.
  (b) click on process tab.
  (c) If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  (d) Hovering mouse on one of the processes will show you a list of all the services.

  Disable Norton.

  This is a free security tool, you can perform. It works with your existing antivirus.
  http://www.Microsoft.com/security/scanner/en-in/default.aspx

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  The Microsoft Safety Scanner is not a replacement for the use of antivirus software that offers continuous protection.

  Once it has run, you have to re - activate Norton. If the Microsoft safety scanner does not remove the virus, I suggest that you contact Norton support because it does not find the virus, he just can not remove it.

• LOCAL SERVICE, SYSTEM and NETWORK of svchost.exe svchost.exe Svchost.exe. SERVICE

  I have these processes running several times, is this normal

  Generally, Yes, if you are looking in the Task Manager, it is normal to see many/many svchost processes running.  You may see 5-10 svchost process running in the Task Manager, maybe less or maybe more.  But what you don't see with the Manager tasks, is running behind them.

  If your system is not afflicted with malicious software, XP important Services running behind svchost - Service processes sometimes alone, sometimes several.

  The username that see you for the svchost process could perhaps LOCAL SERVICE or NETWORK SERVICE and that's how the Services XP to fix themselves to connect to your system using these special accounts, for example:

  LOCAL SERVICE would be local Services - things like the Webclient or the Application Layer Gateway Services.

  NETWORK SERVICE would be Network Services - things like the DNS Client or remote procedure call (RPC) Services.

  These Services of XP run behind/under the svchost process using these special account names.

  Some malware knows that using the Task Manager, you can not see what works behind the svchost process so that the malware is running under one of them hiding so that you can't see.  Apparently, some malware can dress up like a svchost process for still more you cheating.

  When things like that happen, you'll usually see a svchost process that executed the amok much consuming CPU or memory when they normally does, so if you see, you need to run some malware scanners known first, for example:

  Download, install, update and do a quick scan with these free malware detection programs (not at the same time):

  Malwarebytes (MMFA): http://www.malwarebytes.org/products/malwarebytes_free
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  SAS will probably report a lot of tracking cookies and you can just let him delete them.

  They can be uninstalled later if you wish.

  You can see what works behind your svchost process if you use Process Explorer.  PE can be a little intimidating at first because it displays a lot of information, but once you get the hang of it, you start it if you want to solve performance problems.  PE does not settle anything and going just on demand, so it won't bog down your system.

  If you read this article, you will be smarter than the average bear on what is happening with all those svchost.exe process see you in the Task Manager and understand why it is normal to see several svchost running processes in the Task Manager.
