What is taskhost.exe?

Host Process for Windows Tasks is a generic process which acts as a host for processes that run from DLLs rather than EXEs. At startup TASKHOST checks the Services portion of the Registry to construct a list of DLL-based services that it needs to load, and then loads them.

Overview

taskhost.exe executes as a process with the local user's privileges typically within the context of its parent services.exe (Services and Controller app by Microsoft). The file is digitally signed by Microsoft Corporation. This version is designed to run on Windows 7 and is compiled as a 64 bit program.
