What Is Service Host (Svchost.exe)?
Some of the apps and programs on your PC are called stand-alone executables and can actually run via themselves. But, most of these services are DLLs (Dynamic Link Libraries) that don’t contain all of the information needed to run through themselves actually.

Service Host basically helps “host” certain services on your PC. These services are mostly designed in order to run in the background and not cause many problems. However, there are some cases where Service Host apps can actually become corrupt and then begin consuming more processing power than they actually should.
