Enumerations
| ACL_INFORMATION_CLASS Contains values that specify the type of information being assigned to or retrieved from an access control list (ACL). |
| ACTCTX_COMPATIBILITY_ELEMENT_TYPE The ACTCTX_COMPATIBILITY_ELEMENT_TYPE enumeration describes the compatibility element in the application manifest. |
| ACTCTX_REQUESTED_RUN_LEVEL The ACTCTX_REQUESTED_RUN_LEVEL enumeration describes the requested run level of the activation context. |
| AUDIT_EVENT_TYPE Defines values that indicate the type of object being audited. The AccessCheckByTypeAndAuditAlarm and AccessCheckByTypeResultListAndAuditAlarm functions use these values. |
| COMPARTMENT_ID The COMPARTMENT_ID enumeration indicates the network routing compartment identifier. |
| FIRMWARE_TYPE Specifies a firmware type. |
| HARDWARE_COUNTER_TYPE Defines the types of hardware counters being profiled. |
| HEAP_INFORMATION_CLASS Specifies the class of heap information to be set or retrieved. |
| JOB_OBJECT_NET_RATE_CONTROL_FLAGS Specifies types of scheduling policies for network rate control. |
| LOGICAL_PROCESSOR_RELATIONSHIP Represents the relationship between the processor set identified in the corresponding SYSTEM_LOGICAL_PROCESSOR_INFORMATION or SYSTEM_LOGICAL_PROCESSOR_INFORMATION_EX structure. |
| MANDATORY_LEVEL Lists the possible security levels. |
| MEM_EXTENDED_PARAMETER_TYPE Defines values for extended parameters used for file mapping into an address space. |

| TOKEN_INFORMATION_CLASS Contains values that specify the type of information being assigned to or retrieved from an access token. |
| TOKEN_TYPE Contains values that differentiate between a primary token and an impersonation token. |
| TRANSACTION_OUTCOME Defines the outcomes (results) that KTM can assign to a transaction. |
| WELL_KNOWN_SID_TYPE A list of commonly used security identifiers (SIDs). Programs can pass these values to the CreateWellKnownSid function to create a SID from this list. |
