Microsoft Windows 11 Update KB5083769 is not a big update, but on a few PCs, it’s causing BitLocker recovery screen alerts. Microsoft confirmed that its April 2026 security update KB5083769 is triggering BitLocker recovery prompts on some Windows Server 2025, Windows 11, and Windows 10 devices. Microsoft is aware of the problem and is rolling out a fix.
This marks the fourth time in four years that a Patch Tuesday update has triggered unexpected BitLocker issues for users. The same issue surfaced in August 2022, July 2024, and May 2025.
Microsoft, on its support sites, writes
“Some devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key on the first restart after installing this update.
This issue only affects a limited number of systems in which ALL of the following conditions are true. These conditions are unlikely to be found on personal devices not managed by IT departments.”
Microsoft has released a workaround for tech people, and a fix has been rolled out. In addition, this is a one-time recovery event. After entering the BitLocker recovery key, future restarts should boot normally into Windows. If you’re a commercial customer, you can contact Microsoft to obtain the Known Issue Rollback they are offering.
