A lot of users have reported about High CPU usage with taskhost.exe. The good news is that it is not a virus and it will not cause any real harm other than slowing down the system. In the case of taskhost.exe, it is used to host all DLL-based services that are running in Windows. The process is generic and is used to load other entities in it. Different DLL’s might cause multiple instances of taskhost.exe to run in the system. If there are faulty DLL’s loaded into taskhost.exe, this might cause high memory and CPU bottleneck. Killing the process from process explorer might kill the DLL it is hosting and that might close some important programs.
