What is COM Surrogate (dllhost.exe)?

COM, which means Component Object Model, is presented by Microsoft in 1993, as an interface for developers to create COM objects using multiple programming languages. COM’s main purpose is to create thumbnails, process images, videos and files.

Since this situation created some problems, Microsoft aimed to prevent problems by creating a new interface called COM Surrogate. Surrogate performs creating a new COM object outside of the current process and the other COM object crashes in case the COM object crashes.

With the COM mapping process, the host process continues to run without crashing. In addition, COM objects hosted by COM Surrogate process are located on our personal computer with the name “dllhost.exe”.
