Is there a command to set a Windows service to "Automatic (Delayed Start)"?
I made an Elixir app with mix release that runs on Windows as a service.
Because of a erlsrv bug (Windows service fails to start on OS (re)boot · Issue #6076 · erlang/otp · GitHub), I manually set the service to “Automatic (Delayed Start)”.
I would like to automate this step with a command line that I could add in my installer (Inno Setup).
However, it seem that I need the true service name and not the display name to change the service to “Automatic (Delayed Start)”:
PS C:\WINDOWS\system32> sc.exe config "myapp_myapp" start=delayed-auto
[SC] OpenService FAILED 1060:
The specified service does not exist as an installed service.
PS C:\WINDOWS\system32> sc.exe config myapp01da552321887be0 start=delayed-auto
[SC] ChangeServiceConfig SUCCESS
I am not aware of the true service name when installing the service because it is generated randomly. However, there seems to be a way to get the (truncated) true service name from the display name:
PS C:\WINDOWS\system32> Get-Service -Displayname "myapp_myapp"
Status Name DisplayName
------ ---- -----------
Stopped myapp01da552321... myapp_myapp
I am not so familiar with Windows scripting. Is there a way to run a command to change the service to “Automatic (Delayed Start)” with only the display name myapp_myapp as argument?

That works!
The full command I came up with:
for /f "usebackq" %s in (`powershell.exe -Command "Get-Service -Displayname myapp_myapp | Select -ExpandProperty Name -First 1"`) do sc.exe config %s start=delayed-auto
which translates to Inno Setup as:
[Run]
Filename: "{app}\bin\myapp.bat"; Parameters: "install"
Filename: "{cmd}"; \
Parameters: "/c ""for /f ""usebackq"" %s in (`powershell.exe -Command ""Get-Service -Displayname myapp_myapp | Select -ExpandProperty Name -First 1""`) do sc.exe config %s start=delayed-auto"""; \
