The original Surface RT launched with Microsoft's big talk in October 2012 and ran Windows RT, an operating system designed specifically for tablets and all about apps published in the Windows Store.
Windows RT, however, failed to catch on, and Microsoft was one of the few companies to actually support it, with Redmond making a second Surface running the same operating system a year later.
And yet, Windows RT devices have remained rather outdated, even as Microsoft continues to issue security patches for these tablets. And one of those security patches was released earlier this month, and it comes to fix a vulnerability that no one knew about.
You claim that MS16-094 fixes a loophole that allowed users to install other operating systems on devices running Windows RT.
With Windows RT becoming an operating system with no future, many have looked into ways to install a different operating system on the Surface RT, but most attempts have failed due to the locked bootloader and other security systems that Microsoft has put in place.
In the official statement on the Microsoft page they stated:
“A security feature bypass vulnerability exists when Windows Secure Boot incorrectly applies an affected policy. An attacker who successfully exploited this vulnerability could disable code integrity checks, allowing executable test drivers to be loaded on a target device. Additionally, an attacker could bypass Secure Boot Integrity Validation for BitLocker and the Device Encryption security feature. “
