ProcessID (2 bytes):  The client-assigned process identification number.

Reserved_1 (2 bytes):  Padding to enforce alignment of the data on a 4-byte field.

ProcessGuid (16 bytes):  The GUID representing the client process to associate with the process identification number in the ProcessID field.

ProcessNameOffset (2 bytes):  The offset from the beginning of the AUX_HEADER structure to the ProcessName field. A value of zero indicates that the ProcessName field is null or empty.

Reserved_2 (2 bytes):  Padding to enforce alignment of the data on a 4-byte field.

ProcessName (variable):  A null-terminated Unicode string that contains the client process name. This field is offset from the beginning of the AUX_HEADER structure by the ProcessNameOffset field value.
