Remarks

Starting with Windows 10, version 1709, this enumeration supports the values Aes128Cbc and Unspecified. On previous versions of Windows 10, some PlayReady APIs will thrown an exception if these values are used. For this reason, you should check for the presence of the enumeration value by calling ApiInformationIsApiContractPresent and specifying major contract version 5 before using the new enum values. For more information, see PlayReadyContentHeader and PlayReadyStatics.CheckSupportedHardware.
