What is “sihost.exe”?
Windows 10 includes a number of components called Services. These are processes that run in the background without being visible to the end user. One such example is sihost.exe. This program runs all the time even if you turn off your PC. In fact, it is one of the most important programs in the entire OS.
The name of the executable file itself is pretty self explanatory; it stands for Service Host. However, what exactly does this program do? Let us take a look into how it works and why it is essential to the operation of Windows.
