Important: May Windows 10 Updates Trigger BitLocker Recovery – What You Need to Know

Recently, Microsoft confirmed that some Windows 10 devices start showing BitLocker recovery screens after installing the May 2025 security update. This can be concerning, especially because BitLocker is designed to protect your data by encrypting storage drives.

When certain events happen—like a TPM (Trusted Platform Module) update or a hardware change—Windows might trigger BitLocker recovery mode. This means you need to enter a recovery key to access your files. Microsoft is currently looking into reports about a “small number” of devices that are facing this issue due to the KB5058379 update.

On affected devices, multiple failed startup attempts can lead to an Automatic Repair mode. If BitLocker is enabled, players will need to input their recovery key to move forward. Users can check their Event Viewer for LSASS errors and installation failures linked to this update.

It’s important to mention that users have reported mixed outcomes. While some get stuck in a BitLocker recovery loop, others manage to rollback the problematic update after a few attempts.

If you find yourself needing a recovery key, you can retrieve it through Microsoft’s BitLocker recovery portal by logging in with your Microsoft account. For more detailed help on finding your recovery key, check out this support page.

This issue has sparked discussions among users and admins online. Reports indicate that a variety of devices—especially from Lenovo, Dell, and HP—are affected, but it’s unclear if a specific hardware or software fault is to blame. Users have shared their frustrations in forums, with one saying, “After updating, some laptops require BitLocker keys to start, while others won’t start at all.”

For a quick fix, some users suggest disabling Intel’s Trusted Execution Technology (TXT) in the BIOS. If that doesn’t work, you might also consider turning off Secure Boot or other virtualization settings. This advice has been seen on platforms like Reddit, showcasing how communities share solutions during such technical issues.

This isn’t the first time Windows updates have caused BitLocker issues. In August 2024, Microsoft resolved similar problems that arose after the July 2024 updates. Going back even further, August 2022 saw comparable troubles due to another security update, which also caused devices to boot into recovery mode.

As Microsoft investigates this, they aim to provide more insight into the cause of these problems. In the meantime, understanding common troubleshooting steps can be helpful in navigating these unexpected challenges.
