The May 2025 cumulative update for Windows 10, designated KB5058379, has introduced significant issues for users, particularly those operating on Intel’s 10th generation and newer processors. Post-installation, numerous systems are encountering unexpected BitLocker recovery prompts or entering recovery loops, rendering devices temporarily inaccessible.

Root Cause: Compatibility with Intel Trusted Execution Technology

Microsoft has identified the problem as a compatibility conflict between the KB5058379 update and Intel’s Trusted Execution Technology (TXT). This conflict leads to crashes in the Local Security Authority Subsystem Service (LSASS), a critical component responsible for enforcing security policies. When LSASS fails, Windows cannot authenticate users, resulting in the system defaulting to recovery mode.

Affected users report being prompted for their BitLocker recovery keys upon reboot—a process that can be particularly disruptive in enterprise environments where such keys may not be readily available. In some instances, systems experience repeated boot loops or display the Blue Screen of Death (BSOD) before entering recovery mode.

Microsoft’s Response and Interim Solutions

Acknowledging the severity of the issue, Microsoft has updated its support documentation to reflect the known problem and is actively working on a resolution. In the interim, users are advised to:

• Ensure they have access to their BitLocker recovery keys before applying the update.
• Consider postponing the installation of KB5058379, especially on systems utilizing Intel’s 10th generation or newer processors.
• Consult Microsoft’s official channels for any available patches or detailed guidance on mitigating the issue.

This incident underscores the complexities involved in maintaining compatibility across diverse hardware configurations and the critical importance of thorough testing before deploying system updates.
