What Is Svhost.exe? Free Solution To Fix It

If you're wondering what Svhost.exe is and want a free solution to fix it if you're experiencing errors, this should help.

Svhost.exe is is a generic host process name for services that run from dynamic-link libraries (DLLs) within modern versions of the Microsoft Windows operating system.

At startup, Svhost.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 Svhost.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 edition only) can run the following command at the system prompt to get a breakdown:

C:\>tasklist /svc /fi "imagename eq svchost.exe"

Users may then run tasklist with no arguments and match the reported PIDs with the previously shown Svhost instances. If memory usage appears abnormal, the user can look up the service names shown by the sample command in one of the many websites devoted to Windows OS management to see if it is a known buggy service or malware. If no such website comes readily to mind, a search of, for example, windows service ISEXEng in an Internet search engine will lead to the needed information (ISEXEng in this example being the name of the suspicious service).

The Svhost.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).
