Microsoft's acknowledgment of this issue comes after many Windows users and admins have reported seeing devices unexpectedly enter the Windows Recovery Environment (WinRE) and displaying a BitLocker recovery screen after installing the KB5058379 cumulative update released as part of the May 2025 Patch Tuesday. Today, Microsoft confirmed the issue and said it's investigating reports that "a small number" of Windows 10 PCs display BitLocker recovery screens after installing the KB5058379 update. Two years earlier, in August 2022, Windows devices were impacted by similar issues after the KB5012170 security update caused some devices to boot into the BitLocker recovery screen. In August 2024, Microsoft fixed another issue that triggered BitLocker recovery prompts on Windows 10, Windows 11, and Windows Server systems after installing the July 2024 Windows security updates. Microsoft has confirmed that some Windows 10 and Windows 10 Enterprise LTSC 2021 systems will boot into BitLocker recovery after installing the May 2025 security updates. On devices with BitLocker enabled, BitLocker requires the input of your BitLocker recovery key to initiate an Automatic Repair," the company said in a Windows release health update. The BitLocker Windows security feature encrypts storage drives to prevent data theft, and Windows computers typically enter BitLocker recovery mode after events like TPM (Trusted Platform Module) updates or hardware changes to regain access to protected drives. Additionally, while some devices will enter a BitLocker recovery loop after Startup Repair fails to initiate an automatic repair, others will successfully roll back to the previously installed update after several attempts to install KB5058379. "On affected devices, upon installing the update, Windows might fail to start enough times to trigger an Automatic Repair.
