“So much so, that it has been determined that it is no longer feasible for CyberLink to support the Ultra HD Blu-ray playback on newer CPUs and the latest Windows platforms.”
The DRM on 4K Blu-ray needs Intel SGX, and Intel dropped SGX from its 11th generation chips. The discs you paid for no longer play on a new PC. CyberLink’s advice is to keep a 7th to 10th generation CPU and be careful with driver updates. The pirates, as usual, are unaffected.
