Sorry, I misread: I mentally removed the "not" in your 'I do not want
this service to run under a user account' and reinserted it
By default, the service will run as LocalSystem: you
only specify a username to override that default. The value
in Username is passed straight through to the CreateService
Win32 API, and the docs for that:
lpServiceStartName [in, optional]
The name of the account under which the service should run. If the service type is SERVICE_WIN32_OWN_PROCESS, use an account name in the form DomainName\UserName. The service process will be logged on as this user. If the account belongs to the built-in domain, you can specify .\UserName.
If this parameter is NULL, CreateService uses the LocalSystem account. If the service type specifies SERVICE_INTERACTIVE_PROCESS, the service must run in the LocalSystem account.
If this parameter is NT AUTHORITY\LocalService, CreateService uses the LocalService account. If the parameter is NT AUTHORITY\NetworkService, CreateService uses the NetworkService account.
A shared process can run as any user.
If the service type is SERVICE_KERNEL_DRIVER or SERVICE_FILE_SYSTEM_DRIVER, the name is the driver object name that the system uses to load the device driver. Specify NULL if the driver is to use a default object name created by the I/O system.
A service can be configured to use a managed account or a virtual account. If the service is configured to use a managed service account, the name is the managed service account name. If the service is configured to use a virtual account, specify the name as NT SERVICE\ServiceName. For more information about managed service accounts and virtual accounts, see the Service Accounts Step-by-Step Guide.
Windows Server 2008, Windows Vista, Windows Server 2003, and Windows XP/2000: Managed service accounts and virtual accounts are not supported until Windows 7 and Windows Server 2008 R2.
So, although I haven't tried it, it looks as though you can pass
"LocalService" or "NetworkService" and so on if you want to
override the default LocalSystem but don't want to specify a
