Intel removes SGX support from some processors

Intel removes support for SGX

Bleeping Computer reports that Intel has removed SGX (Software Guard Extension) support from the 12th Gen Intel Core 11000 and 12000 processors. As a result, machines with these processors will not be able to play 4K Blu-ray discs.

While Blu-ray discs may seem archaic in 2022, that’s not entirely true. The fact is that they are still in demand, as they often have collectible value, and people just like to have something physical and tangible, and not just watch movies in online cinemas. In addition, Blu-ray discs can offer 4K content without an internet connection, and quality and stability are guaranteed in this case, unlike streaming.

Problems with Blu-ray discs will arise due to the fact that they are protected with DRM, and this technology requires SGX to work.

SGX technology, which Intel introduced back in 2016 with the Skylake generation, allowed PCs to play protected Blu-ray discs for the first time. Alas, now, in the specifications of the 11th and 12th generation Core processors, SGX technology is marked as obsolete, so it will not be available.

Intel removes support for SGX

Apparently, the company decided to abandon SGX due to the fact that in recent years, information security specialists have discovered more and more vulnerabilities in enclave technology. Since most users are not greatly concerned about the ability to play Blu-ray on a PC, this decision was an easy one for the company.

CyberLink, the developer of PowerDVD, has already updated their FAQ to report a problem with the new Intel processors and to state that there is no way to fix it.

The removal of the SGX feature and its compatibility with the latest Windows operating systems and drivers presented a major challenge for CyberLink to continue to support Ultra HD Blu-ray playback in our player. The problem is so severe that CyberLink can no longer support playback of Ultra HD Blu-ray movies on newer processors and the latest Windows platforms.

For now, developers can only advise users to stay on older Intel processors and also not upgrade to Windows 11 to avoid replacing the necessary drivers.

Let me also remind you that we wrote that Serious new vulnerabilities threaten Intel processors.
