Recent Windows 10 update KB5058379 has caused systems to lock up due to an unexpected BitLocker activation. This issue appears linked to Intel Trusted Execution Technology (TXT) in BIOS/UEFI settings, particularly on enterprise machines.
You Should Know: Steps to Disable Intel TXT & Bypass BitLocker Lock
Step 1: Access BIOS/UEFI
Restart your PC and press the BIOS key (typically F2, F10, F12, or ESC) during boot.
Step 2: Locate Intel TXT Setting
Navigate to:
- Security > Virtualization
- Security > Advanced CPU Settings
Step 3: Disable Intel TXT
Find and disable:
- Intel TXT
- Trusted Execution
- OS Kernel DMA Protection
(Note: Keep VT-d (Virtualization for Directed I/O) enabled if present.)
Step 4: Save & Exit
Save changes (F10), reboot, and let Windows complete the update.
Verify BitLocker Status (Command Line)
manage-bde -status
If BitLocker is still active, suspend it temporarily:
manage-bde -protectors -disable C:
Re-enable after update:
manage-bde -protectors -enable C:
Check Update History
Get-WindowsUpdateLog
Force Reinstall Update (If Needed)
wusa /uninstall /kb:5058379
Then reinstall from Windows Update Catalog.
What Undercode Say
Microsoft’s silent patches often trigger unintended security protocols. This bug highlights:
– BitLocker’s sensitivity to firmware changes
– Poor update validation for enterprise hardware
– Need for manual BIOS tweaks in corporate environments
Expected Commands for Further Troubleshooting:
Check TPM status (BitLocker dependency) Get-Tpm
List all installed updates Get-HotFix | Sort-Object -Property InstalledOn
Export update log for analysis Get-WindowsUpdateLog -LogPath C:\UpdateLog.txt
Source: Microsoft Support
Prediction
Future Windows updates may enforce stricter BIOS compatibility checks, reducing false BitLocker triggers. However, admins should prepare for more manual interventions as Microsoft shifts focus to Windows 11.
Expected Output:
A functional system post-update with BitLocker either disabled or properly synchronized with TPM/BIOS settings.
