The svchost.exe is the generic host process for Win32 services on your Windows computer. This process is used to administer Dynamic Link Library (DLL) files and a few other supplementary applications on your Windows computer.
DLL files are primarily files comprising functions that are separately complied, linked and saved from the processes that use them. DLL files help in saving both disk space and system resources. Although useful, DLL files cannot run by themselves and need to use another executable program to do the job. This task is carried out by the svchost.exe file.
By default, the svchost.exe file is located in the %SystemRoot%\System32 folder. When your system is booting up the svchost.exe process checks your Windows registry for the services that need to be loaded at startup. While working as a host to run DLL files, the svshost.exe file creates multiple instances of itself to run different DLL files. Each session of the svchost.exe file can comprise a group of services. This is the reason why you may have multiple services running depending on how and where the svchost.exe service starts. The grouping of services by using the svchost.exe process ensures easier debugging, better control, and a more stable system.
