Windows 10 Update KB5058379 Triggers BitLocker Recovery and Boot Failures

 

Windows 10 Users Report KB5058379 Update Issues – Recovery Mode on Boot

Microsoft's latest Patch Tuesday update—KB5058379, released on May 13, 2025—is causing widespread headaches for Windows 10 users and IT administrators alike. The mandatory security update, intended to address critical vulnerabilities, is unexpectedly forcing devices into Windows Recovery mode and triggering BitLocker recovery prompts, even when no hardware changes have occurred.

What’s Happening?

Users and sysadmins across platforms like Reddit, Windows Latest, and other tech communities are reporting that their systems are being greeted with a message like:

“Enter the recovery key to get going again (Keyboard layout: US)”

Some devices are even encountering a Blue Screen of Death (BSOD) before being pushed to the BitLocker recovery screen.

Ordinarily, BitLocker only prompts for a recovery key after hardware changes, firmware updates, or suspicious boot behavior. In this case, however, simply installing KB5058379 appears to be enough to trigger it—a highly unusual and disruptive event.

Affected Devices

The issue seems to hit a specific subset of users, primarily:

• Windows 10 versions 21H2 and 22H2, including LTSC and Enterprise editions

• Dell, HP, and Lenovo business-class laptops and desktops

• Systems managed via SCCM or WSUS in enterprise environments

One IT admin noted, “Out of 600 machines, about 15 needed manual recovery. All had the KB5058379 update and showed similar behavior.” This aligns with broader reports suggesting a 2–5% impact rate across corporate environments.

Silent from Microsoft—Officially

As of this writing, Microsoft has not updated the official KB5058379 documentation to reflect these issues. However, some affected users have received acknowledgments from Microsoft Support. In one such case, a support representative confirmed:

“We are currently experiencing a known issue with the May Patch KB5058379 titled ‘BitLocker Recovery Triggered on Windows 10 devices after installing KB5058379.’”

Why It Matters

This update is particularly significant because it includes fixes for multiple critical vulnerabilities, including seven zero-day exploits. Being a mandatory update, most managed environments have already rolled it out—making the disruption widespread and urgent to address.

With Windows 10 support ending on October 14, 2025, this may be one of the final major updates for the OS. That raises the stakes for reliability—and highlights how problematic a seemingly routine patch can become.

Temporary Workaround

While a permanent fix from Microsoft is still pending, some IT professionals have found a BIOS-level workaround that can prevent the issue:

BIOS/UEFI Fix Instructions:

1. Reboot into BIOS/UEFI using F2, F10, F12, or Esc (varies by device).

2. Locate Security settings or Advanced CPU Settings.

3. Disable “Intel TXT”, sometimes listed as:

   • Trusted Execution

   • OS Kernel DMA Protection

4. Ensure “VT-d” (Virtualization for Direct I/O) is enabled.

5. Save changes and exit BIOS.

After applying this change, most systems complete the update process without falling into recovery mode or encountering BSODs.
