Svchost error doesn’t appears often, and  if it did, it indicates some serious problem or infection.  Starting from Windows NT OS, Microsoft moved all of the Windows services from executable programs (EXE files) to dynamic libraries (DLL files). The svchost.exe is the program that is needed to start the Service Host process that will use service functions stored in different DLLs. It is the only executable program in this model; however, it is not a single process. This executable runs in multiple instances and hosts one or more services started from different dynamic link libraries (DLLls). If services let share one process space, it helps to save memory resources for something else. This is not the only good point for such a design; it also makes it easier to maintain different operating system components.

Description

This file is located at %SystemRoot%\System32\Svchost.exe. If you use Task Manager, then you probably wonder why so many svchost.exe processes are running at the same time. Well, this is due to possible services failures that might bring down all the service process should it be a single one. With multiple service process instances running, failure of one service doesn’t automatically bring down whole the service system. This design also helped to make Windows NT one of the most stable operating system, and the newer versions of this successful OS (XP, Vista, 7) inherited this Service Host design of the parent.

The services are divided into logical groups that can use one instance of the Host Process to run. However, even shared processes not always help to keep the system resources free from overload. If too many services are running at the same time, you might notice sufficient downfall in the system performance or get the message box with svchost error.

If this is the case, you can stop some service processes and disable unneeded services. Alternatively, you also might try to figure out which one of the svchost.exe processes consumes too much CPU resources by looking at the Processes tab in the Task Manager, and restart found heavy-load process. It might solve the problem. More deep investigation, however, for many PC users presents the problem of being in a dark room with many shadows cast by unknown instances just because the simple thing is somehow hidden. The only thing that anyone can easily figure out is a check mark in the “Show processes from all users” check box in the Task manager. Though, it might be very important to find out where the heavy-load process came from before going on with the efforts for improvements since the process ran in another user OS instance might need his presence before it might be stopped.

How to discover what the services in some particular Service Host instance are running?

1. Windows Vista and XP Pro version let you run task list utility from the Command window. You need start the window, type tasklist /SVC at the prompt, and press Enter. You will get the list of running svchost.exe processes with sublists of cryptic names for the services that are running in each process.

2. If this is not enough, then there are different ways to find out more depending on the system. In Windows Vista you can right-click svchost.exe in the list on the Processes tab in Task Manager and click “Go to Service” option (look at the bottom of pop-up menu). This will open the Services tab in Task Manager with the list of services running under that svchost.exe process. Here you can see what the services are and stop them if needed.

3. The most comprehensive way of the investigation is Process Explorer utility from Microsoft. Here hovering mouse over the list of processes brings pop-up menu with the list of services running in each process. Hovering of your mouse over processes will show you a popup list of all the services. You can double-click on a svchost.exe instance and select the Services tab, where you can choose to stop one of the services if you choose by double clicking the line and going to Services tab where the service might be stopped.

How to stop system services

• Open Services tab from the Administrative Tools option of Control Panel.
• Find needed service in the list, right-click it, and choose Properties.
• Change the startup type of the service to Disabled, and click Stop button to stop it.

However, if you want to take a deeper tour to the world of Generic Host Process error here is 1 main rule:

IF YOU HAVE WINDOWS XP SP2 OR EVEN SP1 IMMEDIATELY INSTALL SERVICE PACK 3. IN 99% OF CASES GENERIC HOST PROCESS ERROR WILL GO AWAY!

Service Pack 3 can be downloaded on the page: Service Pack 3 for XP 32-bit

For those of you who have Service Pack 3 already but have this error below is a set of manual and semi-automatic ways to fix this error. Reasons can be very different thats why try all the methods and reboot so you can see an effect.

1) Registry tweaks:

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters and find “TransportBindName” that will have value \Device\. Double-click on it and remove “\Device\” like in the picture:

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters and find “IsDomainMaster” that will possibly have value “TRUE” or nothing. Double-click on it and change its value to “FALSE” like in the picture:

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole and find “EnableDCOM” that will have value “Y”. Double-click on it and change it to “N” like in the picture:

2) Apply latest Microsoft hotfixes

For 32-bit version of Windows XP:

Update for Windows XP (KB894391)

For 64-bit version of Windows XP:

Update for Windows XP 64-bit Itanium Edition (KB894391)

3) Scan with Antivirus

Error can be caused by malware (like famous mshta.exe executable) you can use your antivirus with latest updates and perform a full scan. Alternatively, you can use Stronghold Antivirus that have 30-days full functional trial:

Download Stronghold Antivirus

Also, you can use free and powerful utility called Combofix that can be found here:

So the process of determining what service or file makes svchost.exe take a lot of CPU resources is similar to what we did in Windows Vista. You open Process Explorer -> Order process by name by clicking on the word Process in the Processes column. Now you will see all svchost.exe instances one by one in one place. Next look at the instances of svchost.exe that are running and double-click the one with the high CPU usage. Look at the Services tab to find out what services are being hosted by that instance of svchost.

There are some services that have problems with running under Windows 7:

Windows Live Mesh Remote Desktop service – this service can be found on some Windows 7 machines. It is a free web-based file synchronization software by Microsoft that is designed to allow files and folders between two or more computers be in sync with each other on Windows. If you don’t use it but you can see it is running – that is a chance that after disabling it your svchost problem will disappear.

Windows Audio service (Audiosrv)

Of course, you can’t simply disable audio service as this will result serious sound problems. But if you see that this service is the reason of your problem – you can do couple of things to fix it. Go to Device Manager and find your audio device. After double clicking on it and going to driver tab you can choose option either to update driver or to roll back latest changes. This can solve your problem.

If you can’t determine what service is causing the problem or how to deal with this or that service you can perform some useful general actions.

1) Use System File Checker – built in system tool that will find and fix corrupted system files. You can run it from command prompt by typing special command:

sfc /scannow

2) Check your startup items. In most cases you don’t need such applications as Adobe, antiviruses, torrent clients, media software to run on startup. Disabling them will increase load speed and possibly fix svchost problem:

3) And of course one of the essential actions you need to perform is to scan the whole PC with some quality antivirus that will find and remove viruses that can also be a reason of high CPU usage. Here is the list of quality antiviruses:

• Stronghold Antivirus (free full functional trial)
• AVG Free Edition
• Avast (has free version)

If above instructions seem to be complex or you can’t find the reason of the problem use advanced utility Svchost Fix Wizard that was designed to solve problems of such a kind.

DO NOT SHOOT THEM ALL!

I mean do not try to stop these processes without knowing what you are doing; otherwise, your system might be in a real trouble. There is a 99% possibility that none of these processes are guilty of some illegal activity. I would say that I am 100% sure that no one of them is “guilty” because svchost.exe virus typically wouldn’t let you stare at your Task Manager – it will just block this utility. However, no one can say for sure that a new sneaky variation of this virus won’t appear and silently hide among all of the looking alike processes.

THEY ARE PERFECTLY LEGAL

With Windows NT Microsoft moved all of the services from executable programs to DLL libraries. This libraries hold functions for system service, and Generic Service Host executable process just call these function as needed. This design is more appealing to programmers because components are easier to manage and maintain. Though, the programmers’ comfort isn’t the main goal of such a design. Generic Service Host process manages services to run without cross conflicts and preserves system resources eliminating the need for running a lot of EXEs at the same time.

Why there are that many Generic Host processes running at the same time? It is needed to make the system less vulnerable to possible service failures. Should all the services belong to one Host Process, the failure of a single one would bring all the services down at once. That is why related services are divided into groups and ran by multiple instances of the Generic Service Host process. Should one service fail for some reason, all other services would still be running and available.

Now, you might be puzzled. How can one find out “who is who”, and which one might be a “bad guy” that you had heard about? It is not that hard as it might look because Task Manager is hiding information from you, and the virus also cannot be hidden completely. There are things that you can easily figure out and the things that might make you overwhelmed with the virus hunt. If you don’t like puzzles, try to make a single click and let Svchost Fix Wizard do the job for you. It is a lot less time consuming way of solving problems related to Generic Host Process.

Well, it seems as you had ignored the temptation of letting professionals solve Generic Host Process problems for you. Then you need some information that will help you to solve the problem on your own if the problem is one that might be easily solved by smart person with a time available to play with puzzles.

First of all, you need to know some basics.  The legal file for Generic Host Process is located at %SystemRoot%\System32\Svchost.exe. File with such a name shouldn’t appear in your autorun list because it is a standard system service. It also shouldn’t reside in some other folder. File that resides in your autorun or is placed in a folder that doesn’t belong to your system is a reason for being suspicious and running a full antivirus scan on your system. Smart man would probably try to make all the files visible and try to find all of them with the system Search utility. If some suspicious file is found, then it might be renamed and the system might be restarted. The absence of problems indicates that renamed file can be safely removed. If after restart the renamed file is found under its original name, but not in the right place for the legal one, than this file is a virus and need to be removed.

To find what the services are running behind some particular legal svchost.exe you can by right clicking on it with your mouse and then clicking “Go to Service” option. Services tab will open and show a list of services ran under one or another svchost.exe process. To see the svchost.exe processes in Processes tab you might need to toggle on the option for viewing all the running processes in Task Manager. Smart man would probably take all the processes from this window to Google search box trying to find out on possible virus entities hiding in. Not that fast, but usually this information can easily be found on the internet.

The possible presence of the virus might be indicated by a high activity shown in one of svchost.exe processes in Task Manager, or it might be indicated by the error pointing at Generic Host Process. However, there is no way to determine if the error is caused by the virus or by something else. It might be caused by the crash of some legal service DLL, unsuccessful system update, etc.

You might need to perform many test and tries before you can find out the truth and solve the problem. You can make a single click and wait for the automated utility performs all the needed things for you. Give it a try, unless you are sure that you don’t need it.

Real svchost.exe file is located in C:\Windows\system32 folder. If you take a closer look to error message you have it can look like this:

Windows cannot find C:\windows\svchost.exe. Make sure you typed the name correctly, and then try again. To search for a file, check the Start button, and then check Search.

Which states that you don’t have file in Windows folder. This error often appear after malware removal that removed svchost.exe virus from Windows folder, while there is still registry entry that tell this file to load on startup. In Hijackthis log this can look like this

F3 – REG:win.ini: load=C:\WINDOWS\svchost.exe

That means that malware created inifile value, mapped to Registry. This can be fixed by Hijackthis but it is strongly recommended to perform antivirus scan after.

Another error can look like this:

Windows cannot find C:\windows\system32\scvhost.exe. Make sure you typed the name correctly, and then try again. To search for a file, check the Start button, and then check Search.

If you look carefully you can see that it is sCVhost.exe file but not sVChost.exe that should be. In Hijackthis log this error can be represented by O4 line:

O4 – HKLM\..\Policies\Explorer\Run: [Generic Host Process] C:\WINDOWS\system32\scvhost.exe

It even named the process “Generic Host Process” to make you sure there is nothing suspicious. Actually, virus copied this file to system32 folder and added auto-loading Registry entry. After your standard antivirus or Windows Defender located and removed the file entry was still there saying your PC to load non-existing file which result in this error.

Other known cases are:

Windows cannot find C:\Recycled\SVCHost.exe. Make sure you typed the name correctly, and then try again. To search for a file, check the Start button, and then check Search.

This error appears after infecting with Rungbu.b virus that can be removed with True Sword or Malwarebytes Antimalware. To redeem this error you need to go to Registry Editor and locate key:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\Current Version\Explorer\Winlogon

On the right side locate entry Shell and change its value from

Explorer.exe C:\Recycled\Svchost.exe

to

Explorer.exe

After restart error should disappear.

One more popular problem states:

Windows cannot find ‘C:\WINDOWS\system32\dxdll\svchost.exe’. Make sure you typed the name correctly, and then try again. To search for the file, click the Start button, and then click Search.

Reason of this error is pretty much the same and it can be fixed by Hijackthis or using registry Editor. Just go to Edit -> Find in Registry Editor and type:

dxdll\svchost.exe

Remove entry that will contain C:\WINDOWS\system32\dxdll\svchost.exe or remove line C:\WINDOWS\system32\dxdll\svchost.exe in value that will be found.

If you would like to fix this problem manually you should learn the following:

1) Almost all Norton products have the ccsvchst.exe file. It is essential for this file to be installed of these software products since the user interface where the user interacts with the computer is made by this file.
2) This file usually located in The file is located in the C:\Program Files\Common Files directory.
3) Symantec Event Manager and the Norton Internet 2007 Security Suite (or later) actively use this file.

A) Update

Main way to fix this if you want to keep Norton products on your PC is to perform update of the program, databases, modules. You can use instructions here and update your particular product up to latest date:

So as in previous case when I start Process Explorer on my PC and sort processes by names I see list of 14 svchost.exe processes with different PIDs and two of them are using more memory and CPU than other 12.

One of them was described in one of the previous articles. Today we take a close on svchost.exe netsvc host group.

As you can see I choose exactly that svchost.exe that you might have problem with:

C:\Windows\system32\svchost.exe -k netsvcs

If I go to the threads tab I can see list of alls services that use this svchost.exe process to start themselves, DLL files that contain the core of this services and most important percentage of process resources it is using.

In my case, there is MMCSS service using 0.05 percent of CPU which is absolutely normal and I don’t care about it. However, if MMCSS will take a huge amount of process resources I can turn the service off as it is not really essential (it is responsible for relative prioritization of work for multi task system intended mainly for multimedia applications). In your case you can have some malicious activity service taking 25% or 30% of CPU and you can kill it as well. But make sure it is really third-party and malicious or you can stop some essential process which can end with a system malfunction or freeze. Read about service taking your CPU as much as you can find in Google and if there is no info or it is proven to be malicious you can kill it without problem.
