    Microsoft confirms KB5082063 BitLocker recovery prompts on some Windows Server 2025 devices

    Initial Disclosure

    Microsoft confirms that some Windows Server 2025 devices with BitLocker enabled can boot into BitLocker recovery after installing KB5082063 when the device uses the Group Policy 'Configure TPM platform validation profile for native UEFI firmware configurations' with PCR7 included, has the Windows UEFI CA 2023 certificate in Secure Boot DB, and is not already running the 2023-signed Windows Boot Manager; the company says the recovery key should be needed only once and advises admins to remove the Group Policy before deployment or use a Known Issue Rollback (KIR).
