Set this property to "True" if your service needs to be able to interact with the desktop. A Win32 limitation of this feature is that the user account used to start a service which interacts with the desktop must be the LocalSystem account. This means that you should leave the Start Service As User (userName) property blank.

See the CreateService Win32 API help documentation for more information. When this property is true, the SERVICE_INTERACTIVE_PROCESS flag is set within the dwServiceType parameter.
