Your system should restore all damaged drivers when the recovey disk is used. You should be able to select repair or recovery from your OS install disk. I can't offer any more specific info, as I do not use XP, but this technique worked when my Windows Vista and Windows 7 PCs lost the boot manager

This is going to be a tough one to fix. since I don't know which svchost you have deleted from the system.
usually when that happen the only solution is to reinstall the OS. even try to fix it from the registry key, the key and the pointer will be there, but not the excution file, and there is not way which svchost control what services.

The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services allows for better control and easier debugging.

Svchost.exe groups are identified in the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\SvchostEach value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service names that are extracted from the registry key.

Everytime i open my computer, ah pop-up windows say's WINDOWS CANNOT FIND SCVHOST.EXE


Hi,

First, I'll let you know what's going on, then I'm going to post from Microsoft, what svchost.exe does, and how to find out where the problem is. I can help you further if you need it.

Svchost.exe is a program in WIndows XP Pro that will start services in your computer during startup. It sounds like you have deleted a program and "service host" is still looking for it to open on startup. This can happen if the program was removed without using the correct removal procedures. It is still listed in the registry and your computer is still trying to access it. DO NOT edit your registry unless you know what you are doing. You could create a catastrophic failure of Windows. There are programs that will remove registry entries if those entries are no longer valod. You can fing a free program for this function at web sites like www.nonags.com

Following is information from the Microsoft web site:

The Svchost.exe file is located in the %SystemRoot%\System32 folder. At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services allows for better control and easier debugging.

Svchost.exe groups are identified in the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\SvchostEach value under this key represents a separate Svchost group and appears as a separate instance when you are viewing active processes. Each value is a REG_MULTI_SZ value and contains the services that run under that Svchost group. Each Svchost group can contain one or more service names that are extracted from the following registry key, whose Parameters key contains a ServiceDLL value: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Service To view the list of services that are running in Svchost:
  1. Click Start on the Windows taskbar, and then click Run.
  2. In the Open box, type CMD, and then press ENTER.
  3. Type Tasklist /SVC, and then press ENTER.
Tasklist displays a list of active processes. The /SVC switch shows the list of active services in each process. For more information about a process, type the following command, and then press ENTER: Tasklist /FI "PID eq processID" (with the quotation marks) The following example of Tasklist output shows two instances of Svchost.exe that are running. Image Name PID Services
========================================================================
System Process 0 N/A
System 8 N/A
Smss.exe 132 N/A
Csrss.exe 160 N/A

Unknown file


In software Svchost.exe is a generic host process name for services that run from dynamic-link libraries (DLLs) within the Microsoft Windows operating system.
At startup, Svchost.exe checks the services part of the registry to construct a list of services that it must load. Multiple instances of Svchost.exe can run at the same time. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services permits better control and easier debugging, but it also causes some difficulty for end users wishing to see the memory usage or vendor legitimacy of individual services and processes. End users in Windows XP Professional (and derivatives, such as Windows Server 2003 and Windows XP Media Center Edition) can run the following command at the system prompt to get a breakdown:
tasklist /svc /fi "imagename eq svchost.exe" (NB: This command does not work in Windows XP Home.)
Due to being widespread among running processes, svchost.exe has long been a common disguise used by malware to hide its presence from the user. (One of the common trojan horses deceptively uses scvhost.exe). Users may then run tasklist with no arguments and match the reported PIDs with the previously shown Svchost instances. If memory usage appears abnormal, the user can look up the service names shown by their command on the internet to see if it is a known service or malware.
The Svchost.exe file is located in the %SystemRoot%\System32 folder. The main registry key involved at bootup is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SvcHost (values in this key will show the user at least a partial list of the actual processes behind instances of svchost).
The 30 April, 2007 release of WSUS 3.0 led to reports of svchost.exe issues, including 100% CPU usage, memory hogging, and excessive laptop fan/power usage.[1]

Svchost


"Svchost.exe" (Generic Host Process for Win32 Services) is an integral part of Windows OS. It cannot be stopped or restarted manually. It manages 32-bit DLLs and other services. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. In normal conditions multiple instances of Svchost.exe run at the same time. Each Svchost.exe session can contain a grouping of services, so that separate services can be run depending on how and where Svchost.exe is started. This allows for better control and debugging. The svchost.exe file is located in the folder C:\Windows\System32. In other cases, svchost.exe is a virus, spyware, trojan or worm! To detect if it's a virus sometimes it will add letters to the Svchost to read thus SSVCHOST or SVCCHOST or something like that, thus making multiple services to run and slow down the computer, if that is the case the current antivirus you are using is not removing the virus, this can be done in the registry, its a complicated process if you do not know how to do it, so i would suggest you purchase a registry cleaner. NOTE: remember to backup the registry before you clean it

Svchost cant be written


can you go to control panel, administrative tools and event viewer and look in applications and software and see if there are any red crosses that show up and if so right click on them and go down to properties and it will send you to microsoft for a possible solution. But also the services host, which is the svchost.exe is a complete programme which runs the internet ports and allsorts of things. Make sure you have no spyware or trojans, so run virus check and an antispyware programme to check for other nasties, you can get a free one here:- http://www.download.com/3000-2144-10045910.html Also run a registry cleaner, again you can download this excellent free ccleaner programme to get rid of all temp files and unrequired system files http://www.filehippo.com/download_ccleaner/ after all is run restart pc and see if its still popping up with the fault.
