My software includes a service created using Windows functions (OpenSCManager and CreateService), named "MyService".
Once the service is created (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Service\MyService), The group value of MySevice is "MyGroupOfServices". And the group "MyGroupOfServices" is added to "List" value in registry key (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ServiceGroupOrder).
At this point, the service works fine.
After 19H1 upgrade (version 18353), the service group order is changed: "MyGroupOfServices" is not present anymore in list.
Why the 19H1 upgrade change the registry "ServiceGroupOrder"?
