Believe it or not, there’s another blue screen that’s popping up on some Windows machines. Microsoft says some Windows 11 devices will see a blue BitLocker recovery screen at boot after installing the July 2024 Windows security update. The issue isn’t widespread, but those impacted will have to enter a recovery key to get a PC to boot properly. A fix is on the way.

Microsoft made Secure Boot a requirement for Windows 11, and has been pushing to use the technology to secure against BIOS rootkits for years. Now, researchers have found that Secure Boot has been compromised on more than 200 device models from Acer, Dell, Gigabyte, Intel, and more. Ars Technica reports that an important cryptographic key was published on GitHub in 2022, by “someone working for multiple US-based device manufacturers.”
