Default Behavior

Hyper-V PowerShell Direct Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Hyper-V PowerShell Direct Service is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If Hyper-V PowerShell Direct Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the vmicvmsession service has failed to start due to the error.
