“This update broke BitLocker for me” — Windows 11’s April patch is locking out PCs, but here’s the fix that works
Microsoft’s April 2026 Security Update (KB5083769) for Windows 11, rolled out beginning April 14, 2026, has triggered BitLocker recovery mode on some PCs due to a faulty BitLocker configuration issue. The update introduced various visual changes and system improvements, but affected users report being locked out of their systems and forced into BitLocker recovery mode after installation.
Although the full extent of the problem remains unclear from available information, the issue appears to stem from how the update handles existing BitLocker configurations. Microsoft has acknowledged the problem, and a workaround has been identified to resolve the lockout situation. The affected users can regain access to their systems using the documented fix, though the exact nature of the workaround was not detailed in available reports.
This incident reflects a recurring challenge with major Windows updates, where patches intended to improve system security and functionality occasionally introduce unintended side effects for users with specific configurations. IT administrators and users with BitLocker-protected systems were advised to exercise caution when deploying the April 2026 update, or to apply the available fix if they encountered the recovery mode issue.
