SVCHOST.EXE 창에서 일정하게 달리고 완전하게 근본적인 그 신비한 과정의 한개는 이다, 그러나 하고 있는 무엇을 당신은 절대 모릅니다 정확하게. 이렇게 SVCHOST.EXE는 무엇인가? 각 SVCHOST.EXE 과정 안쪽에 달리고 있는 프로그램 및 실제적인 서비스을 확인하는 것은 특히 과정이 당신의 CPU의 99 100% 높은 쪽으로 먹을 때, 의 값이 있는 업무 우물 알고 있기이다!

이렇게 우리가 해결책으로 급강하하기 전에 이 과정이 실제로 하는 무슨, 그리고 얻자 당신이 대략 발생할지도 모른 어떤을의 문제 해결하는 갈 수 있는 어떻게의, 깊은 이해를. 첫번째로, svchost는 "서비스 주인을" 뜻하고 건의하는 이름으로 무엇이 정확하게 한다: "주인" 서비스에 도움. 창에 있는 서비스는 비록 당신이 로그인되지 않더라도 당신의 컴퓨터가 켜져 있을 때 간단하게 특정한 일을 하고 배경에서 항상 실행하는 운영 체계에 있는 프로그램이다.

당신이 독립 executables로 뛰기에 익숙하다 대부분의 프로그램, 그런 .EXEs. 그러나, 대부분의 서비스는 독자적으로 달릴 수 없는 DLLs의 모양으로 실행된다. 그러므로, svchost는 그 DLLs 적재하고 그들을 자체를 달린다. 저것은 당신이 창 업무 매니저를 열 때, 당신이 svchost.exe 과정 달리기의 낱단을 볼지 왜 이다. 당신이 업무 구유에 정보를 더 원하는 경우에, 밖으로 체크 위에 나의 기사 업무 매니저 이해.

당신은 기억 위 각종 양을 사용하여 현재 내 컴퓨터에 달리는 8개의 svchost 과정이 다는 것을, 모두와 다른 사용자 명의 밑에 달리기 주의할 것이다. 이렇게 그들중 하나가 100%의 과량으로 높은 CPU 사용법에, 실제적인 신청 달리기를 확인할 어떻게 다는 것을 우리 달리고 있다는 것을 생각한?

실제로 대략 가는 2가지의 방법이 이것 있다: 그것을 전부 명령 프롬프트 및 서비스 공구를 사용하는 또는 타업체 애플리케이션을 를 사용하는 수동으로 하기. I’m going to mention both here in case one does not work for you.

Identify svchost.exe processes using command prompt (hard way)

1. First, go ahead and click on Start and then Run and type in CMD and click OK

command prompt

2. Type in the following into the command window and press Enter

tasklist /svc /fi “imagename eq svchost.exe

You should get an output as shown below with the name, PID, and service description

svchost process

You’ll now see each svchost process along with it’s unique ID number and the services it is responsible for running. However, these names are still very cryptic and are all short hand names. In order to get some more useful information about the process, we can use the Services browser in Windows.

3. Right-click on My Computer, choose Manage. On the resulting screen, choose Computer Management and then choose Services and Applications. Finally, choose Services.

4. Now try to match the cryptic Windows service name with the easily readable names in the Services tab. This is a little and can take some time because if you take the process with ID 1436 and it’s name WudfSvc, you have to try to find it in the list. If you double-click on one the service names, you’ll see their cryptic name also, so that’s how you can match them up. In my case, I guessed that the W means the process starts with Windows… and opened them until I saw a match.

As you can see, the Windows Driver Foundation service is actually called WudfSvc also!

Use Process Explorer to find programs running as svchost.exe (easy way)

If you found to be too difficult, there is a much easier way! Check out the Process Explorer tool from Microsoft (originally from SysInternals). The tool is completely free and gives you detailed information for each process currently running.

Once you download it, just run the exe file as it does not have to be installed. Hover your mouse over the svchost process and you’ll get a popup showing you which service is running under that process.

Fixing SVCHOST high CPU usage

Now that you have figured out exactly which process is eating up all of your CPU, we can address how to fix it. If you have found that the process is not a Windows process, such as Windows Update or Windows Firewall, etc, then simply kill the process and uninstall the program.

However, most of the time that this problem occurs, it has something to do with a Windows process. The best solution in this case is to install all of the latest updates from Microsoft’s web site. If you’re not able to do so normally in Windows, try restarting the computer in safe mode and try it again.

Also, if you can get to the Services tab like we did above, go ahead and right-click on the service and choose Disable. Even if it’s Windows Update or the Firewall, don’t worry, you can re-enable it later. Then restart the computer and go to Microsoft’s web site and manually get the updates. Re-enable the service and restart the computer again and hopefully things are working!

In order to disable a service in Windows, right-click on it from the Services tab and choose Properties.

disable services

Next choose Disabled from the Startup type combo box located in the middle of the dialog box:

disable service

I have gone through this process a couple of times and it’s worked for me. So again, it’s disable the service, restart computer, install updates manually, re-enable service, and then restart computer again.

    This information was “right on” and helped me find the process causing the CPU high usage. The process involved happened to be a HP monitoring process for a network printer that I really didn’t need all that much on this computer. I disabled it and the problem disappeared. My question, rather than disableing it, could I not have made it a “manual” function so I might use this feature?

    Thanks for your help.

    Jerry

    This is the best explanation of sleuthing out svchost.exe that I have read. Most articles either say “it a Windows thing, you wouldn’t understand” or “it’s a virus so nefarious that none of the 12 anti-virus programs I used could detect it.” Thanks for *teaching* me about svchost.exe. You are now on my RSS reader and an official genius.

    THANK YOU
    I tried everything, from every web site, telling me it was a virus, or related to Microsoft updater and no luck.
    I tired registry mechanics and no fixes. Finally I read your web site, downloaded the Microsoft Process Explorer, and found the problem with svchost.exe was related to some software that came with a new printer I had recently installed.
    I un-installed the software that was of no use anyway and everything works. Likewise, the CPU usage is normal. Thanks you, have the correct answer!
