While initially Microsoft did not report any known issues with the latest Patch Tuesday, the company has now added that all systems which have received the updates are affected by a BitLocker-related issue. This means Windows 11, Windows 10 (KB5082200), as well as Windows Server 2025 and Server 2022, are all hit by this.
The company has explained that the issue is due to an unrecommended BitLocker-based Group Policy configuration. This leads to a BitLocker Recovery key prompt on affected systems. The good news, Microsoft says, is that the key will only be necessary to be entered once, plus it also seemingly affects only a limited number of systems.

The good news, Microsoft says, is that the key will only be necessary to be entered once, plus it also seemingly affects only a limited number of systems. Such devices have to meet the following criteria:
- BitLocker is enabled on the OS drive.
- The Group Policy "Configure TPM platform validation profile for native UEFI firmware configurations" is configured, and PCR7 is included in the validation profile (or the equivalent registry key is set manually).
- System Information (msinfo32.exe) reports Secure Boot State PCR7 Binding as "Not Possible".
- The Windows UEFI CA 2023 certificate is present in the device's Secure Boot Signature Database (DB), making the device eligible for the 2023‑signed Windows Boot Manager to be made the default.
- The device is not already running the 2023-signed Windows Boot Manager.
