Intel has removed the Software Guard Extensions (SGX) feature from its 11th generation and newer CPUs, which is required to play Ultra HD Blu-ray movies on Windows platforms. As a result, CyberLink can no longer support Ultra HD Blu-ray playback on newer CPUs and the latest Windows platforms. Users with older compatible platforms are advised to avoid updating their operating system or Intel drivers to maintain support for Ultra HD Blu-ray playback. This change may cause inconvenience to legitimate customers who have purchased Ultra HD Blu-ray movies.
