DRM is designed to protect content from thieves. In many cases, though, it causes more problems than it helps. The latest Intel Core 11000 and 12000 processors remove Intel SGX, causing Ultra HD Blu-ray discs to no longer play on modern PCs.

The issue was first reported by CyberLink, a maker of a popular media player. Intel has dropped support for the Intel SGX DRM in its latest chips, leaving on the 7th through 10th generation Intel chips able to handle Ultra HD Blu-ray discs on PC.

“The removal of the SGX feature, and its compatibility with the latest Windows OS and drivers, has caused a substantial challenge for CyberLink to continue supporting Ultra HD Blu-ray movie playback in our player software. 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.” said the company in a customer service post.

Intel didn’t drop SGX without reason. It was commonly targeted by researchers who discovered numerous vulnerabilities and attack methods that could be exploited, as pointed out by Bleeping Computer. These holes prompted Intel to remove it.

We also have to imagine the number of PC users watching 4K Blu-ray movies on their computers is low enough that the openings left by SGX were worth closing.

CyberLink also speculated that Intel could remove SGX from existing processors. The company advises users to “continue using the 7th-10th generation Core series of Intel CPUs and motherboards that support the Intel SGX feature.” It also said to avoid updating to Windows 11 to ensure you keep support for the technology if you enjoy watching 4K Blu-ray discs.

We can’t say whether Intel will actually do this, but you also need to consider whether using a subset of discs is worth keeping your computer behind on current updates. Personally, I’d rather have the latest drivers and operating system, but it’s ultimately your decision.
