com surrogate is a Windows process that acts as a host for COM-based applications that require additional processes to run. It is also known as "dllhost.exe" and is responsible for executing COM objects outside of the original process that requested them.

COM Surrogate runs in the background and is typically used by Windows Explorer to generate thumbnail images for various types of files or preview them. It helps prevent crashes in the main process by isolating COM-based applications in a separate process, making the system more stable and secure.

In summary, COM Surrogate is a critical component in the Windows operating system that helps to improve system stability by running COM-based applications in a separate process. It is especially useful for tasks such as generating thumbnails and previews in Windows Explorer.
