Microsoft reported that it has identified a potential security vulnerability in Windows 10, specifically affecting users during May’s critical security update. The issue arises when users attempt to run the update, causing Windows to display a victimized window—bitLocker Recovery screens—and triggering a blue screen of death (BSOD) when needed. Microsoft issued an update emphasizing that these recovery screens appear at startup and are distracting from updating.
The problem specifically affects users whose system is enabled with Intel Trusted Execution Technology (TXT) on Intel vPro processors. For those users who have not yet installed May’s update, an out-of-bounds update is recommended. Microsoft instructed users to disable intelVT for Direct I/O (VTD, VTX) andVTX in their BIOS or UEFI settings. This action requires temporarily using the BitLocker Recovery Key (KB5061768) and restarting Windows after installation.
Windows users should also note that Microsoft is not capable of retrieving, providing, or recreating lost BitLocker recovery keys. However, an updating link is available on the support page to help users find their key. This update primarily impacts enterprise users, particularly on Intel-based systems, due to the unique distinction between consumer and enterprise devices in倚ored setups.
Windows Animation Latest (WAL), which was introduced earlier in May, was the first software to flag this issue and issue an update. In some cases, the update processes display a ‘Enter the recovery key to get going again (Keyboard layout: US)’ screen and require users to input a key. Microsoft highlighted that the Circuit Error bytes written during the update process prevent the recovery key from being generated, leading to the observedgreens in bitLocker, which are temporary overlays.
Microsoft also addressed the issue by providing a step-by-step workaround for entangled Intel VT (VTX),싸, or regular VTD configurations. Regardless of the underlying configuration, these devices can be semi-automatic by disabling VTX/VTD and temporarily overwriting the BitLocker key recovery system at startup.
As a result, users are advised to restart their system after installing the out-of-bounds update and disable VTX/VTD/TX configurations to navigate through the system without displaying bitLocker Recovery screens. This adjustment will not affect application downloads but will ensure that the BitLocker process on the system will use the correctges key in key recovery for other plugins and tools.
On the broader front, Microsoft’s May update marked a significant achievement in addressing concerns about Windows 10 recalling users of key storage devices (e.g., Copilot+ MB100s) while pushing hundreds of millions to upgrade by the October deadline. However, the equally critical but somewhat less controversial issue affects only users on Intel vPro-based Intel customers, a segment that represents 37% of Azure employmes and likely to continue growing in the coming months.
