Remarks

This structure is used by the ChangeServiceConfig2 function to specify the protection type of the service, and it is used with QueryServiceConfig2 to retrieve service configuration information for protected services. In order to apply any protection type to a service, the service must be signed with an appropriate certificate.

The SERVICE_LAUNCH_PROTECTED_WINDOWS and SERVICE_LAUNCH_PROTECTED_WINDOWS_LIGHT protection types are reserved for internal Windows use only.

The SERVICE_LAUNCH_PROTECTED_ANTIMALWARE_LIGHT protection type can be used by the anti-malware vendors to launch their anti-malware service as protected. See Protecting Anti-Malware Services for more info.

Once the service is launched as protected, other unprotected processes will not be able to call the following APIs on the protected service.
