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.

Restore Default Startup Configuration for Hyper-V PowerShell Direct Service

2. Save the Win10_vmicvmsession_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

The vmicvmsession service is using the icsvc.dll file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
