Set service Startup type in WiX installer

Question

I am trying to set a pre-installed service\'s startup type to Automatic, using WiX. Another task was to start the service on install, which I achieved with:

Answer 1

Solved by editing the registry via RegistryKey, see example:

<RegistryKey Root="HKLM"
             Key="SYSTEM\CurrentControlSet\Services\[Service Name]"
             Action="create">
    <RegistryValue Type="integer" Name="Start" Value="2" />
    <RegistryValue Type="integer" Name="DelayedAutostart" Value="0" />
</RegistryKey>

Note service may appear as Automatic (Delayed Start) in Services GUI. However, after restarting, Services GUI displayed the service startup type as Automatic.

Answer 2

Set the "DelayedAutoStart" parameter to "no", rather than "yes".

Answer 3

MSI doesn't support changing the startup type of a service that the package doesn't install. ServiceConfig doesn't let you get around that:

Applies only to installed auto-start services or services installed by this package with SERVICE_AUTO_START in the StartType field of the ServiceInstall table.
