| You can't know exactly about svchost but by interrogating Windows itself . Some services launched by Svchost are mandatory. Get the script file and launch it to have more infos : http://thecric.free.fr/WMI/Services/Services%20from%20svchost.exe.vbs
This link is in french (sorry ;-)

| The svchost.exe file is located in the folder C:\Windows\System32. In other cases, svchost.exe is a virus, spyware, trojan or worm!

| El proceso se ejecuta al iniciar el sistema, y chequea parte de los servicios del registro para hacer la lista de servicios que deben abrirse. Por lo general, múltiples instancias del proceso Svchost.exe son ejecutadas al mismo tiempo. Cada una de estas instancias puede contener un grupo de listas de servicios.
Este agrupamiento de servicios permite un mejor control y fácil depuración, pero también causa algunas dificultades a los usuarios. Esto se debe a que el mismo nombre de archivo es utilizado por virus, espías, caballos de troya y otros malwares para ocultar su actividad.

| It would be nice if Microsoft could comment! It would sae all tis hassle.

R Phillips
| as this file can be used to hide other programs such as malware, this makes svchost a risk, while it is a part of the WinXp OS. it is manipulated by Malware programmers
|
totally confused guy
| I have 15 of svchost.exe processes running!!!!
I have Vista business I have scanned my computer with many different antivirus software's including Norton (which I hate), McAffee (it's alright), AVG Free (best free version ever), and my favorite...Kaspersky. So far, no virus/trojan/worm/spyware/etc. have been found so i don't know why so many of these processes are running at once.
is there a way to limit the number of svchost.exe processes running? thx

| Hey Gennessis thats the best explanation I've ever seen about Svchost.exe, I've always know that it was used by Windows to run all the services that run in the background, I just never figured out why I have 6 of them running at once. But now that you mentioned it, its a good thing that all those services aren't running under one roof or we'd have more crashes than we do with Windows. NOTE: to those of you that are getting all of your RAM eatin up by Svchost.exe...do like I did and add more RAM, I've got 1.8 GB and I don't even notice the 6 svchost.exe I've got running all the time plus the other 34 processes for a total of 40 always running when I look at my task manager.

| What is svchost.exe And Why Is It Running?
You are no doubt reading this article because you are wondering why on earth there are nearly a dozen processes running with the name svchost.exe. You can't kill them, and you don't remember starting them… so what are they?
So What Is It?
According to Microsoft: "svchost.exe is a generic host process name for services that run from dynamic-link libraries". Could we have that in english please?
Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective this makes more sense for reusability… but the problem is that you can't launch a .dll file directly from Windows, it has to be loaded up from a running executable (.exe). Thus the svchost.exe process was born.
Why Are There So Many svchost.exes Running?
If you've ever taken a look at the Services section in control panel you might notice that there are a Lot of services required by Windows. If every single service ran under a single svchost.exe instance, a failure in one might bring down all of Windows… so they are separated out.
Those services are organized into logical groups, and then a single svchost.exe instance is created for each group. For instance, one svchost.exe instance runs the 3 services related to the firewall. Another svchost.exe instance might run all the services related to the user interface, and so on.
So What Can I Do About It?
You can trim down unneeded services by disabling or stopping the services that don't absolutely need to be running. Additionally, if you are noticing very heavy CPU usage on a single svchost.exe instance you can restart the services running under that instance.
The biggest problem is identifying what services are being run on a particular svchost.exe instance…
Checking From the Command Line (Vista or XP)
If you want to see what services are being hosted by a particular svchost.exe instance, you can use the tasklist command from the command prompt in order to see the list of services.
tasklist /SVC
The problem with using the command line method is that you don't necessarily know what these cryptic names refer to.
Checking in Task Manager in Vista
You can right-click on a particular svchost.exe process, and then choose the "Go to Service" option.
Disabling Services
Open up Services from the administrative tools section of Control Panel, or type services.msc into the start menu search or run box.
Find the service in the list that you'd like to disable, and either double-click on it or right-click and choose Properties.

| Es totalmente normal que Svchost.exe se ejecute al mismo tiempo. Lo que no es normal es que esté fuera de C:\WINDOWS\SYSTEM32. Clicar sobre el archivo o proceso en cuestión,clicar en propiedades o en más detalles,dependiendo del administrador de procesos que tengais, y fijaros en la ruta que tiene, si no es C:\WINDOWS\SYSTEM32 entonces puedes tener un problema. Lo que tienes que hacer,para salir del paso,es abrir el BUSCADOR de WINDOWS,en BUSCAR ARCHIVOS Y CARPETAS pones el nombre entero del proceso incluida su extensión,marcas para que busque por todo tu sistema,incluidos archivos ocultos,comprimidos,etc.. OSEA TODO. Y esperas a que termine la búsqueda.Una vez terminada buscas el archivo que sea el BUENO, el que tiene que aparecer en ; C:\WINDOWS\SYSTEM32 . Ese ni lo tocas. Ahora a todos los demás les CAMBIAS de NOMBRE,POR EJEMPLO poniendo un número antes de la extensión; svchost1.exe , svchost2.exe,etc.. y así a todos los que sean iguales.NO LOS ELIMINES,algunos serán válidos, sobre todo si tienes instalado el servipack2 de windows.Pues ya está, una vez que has puesto un numerito a cada archivo,EXCEPTO AL BUENO cierra todo y reinicia el ordenador. De ésta manera cuando reinicies se cargará el archivo BUENO y los otros quedarán en el olvido.Para saber cual de los "MALOS" es perjudicial lo que tienes que hacer es el proceso inverso.Osea abrir el BUSCADOR de WINDOWS, buscar los archivos y una vez encontrados les quitas eL número y los dejas COMO ESTABAN.Ahora sólo les tienes que pasar un ANTI-VIRUS A LOS ARCHIVOS Y LISTO. Si el ANTI-VIRUS no te elimina todos, es por lo que ya he comentado antes,el archivo o archivos"en teoría" no son corruptos son parte del servi-pack de windows y para que estos archivos no interfieran en un futuro, los dejas DONDE ESTAN pero les vuelves a poner un numerito antes de la extensión.Estos te podran servir de copia de seguridad en caso de que el BUENO se pierda o lo borres accidentalmente.Sólo tendrás que quitarle el numerito y enviarlo a la ruta donde estaba el PERDIDO.Si esto ocurre, y tienes más de dos archivos iguales,fijate antes en la versión, pues la del ServiPack suele ser idéntica a la buena, la otra u otras suelen ser versiones inferiores y seguramente estaran en la ruta del desintalador del servi pack.Sirven lo mismo pero siempre una versión actualizada es una versión mejor. que quieres que te diga .. Pos nada .. menudo royo que he soltado... ea..!! a disfrutarlo.!!!

The process is run at system startup and checks part of registry services to the list of services to be opened. In general, multiple instances of Svchost.exe process are implemented at the same time. Each of these bodies may contain a list of services. This grouping of services allows better control and debugging easier, but also cause some difficulties for users. This is because the same file name is used by viruses, spyware, Trojan horses and other malwares to conceal their activity.
