While the computer is booted up in safe mode, this would be a good time to clean up some unwanted applications and stop them from starting up as soon as the computer starts up. This will not only help boost performance but may also resolve the host process error at the same time by stopping the conflicting program from opening during startup and causing the conflict with the Windows system service. Using a utility called MSconfig, there are options to disable programs from starting up when the computer boots up and other options for special startup modes. MSconfig is a good tool for helping boost performance and troubleshoot system startup issues. For more information, read this article on using MSConfig in Windows.
By following these simple steps in troubleshooting problems such as “error host process for windows services stopped” and others, you will find that many of the vague errors can be resolved relatively easy.
