A helping hand to our customers

During patch Tuesday on august 9, 2022, Microsoft released a Windows update that can cause BitLocker to activate recovery mode and prompt the end-user for a recovery key.

With the update KB5012170, Microsoft has fixed some security vulnerabilities in Secure Boot by updating Secure Boot DBX – which can cause BitLocker to activate recovery mode.

The prompt is presented only once after the update has been installed and the computer has been rebooted.

Due to the above, CapaSystems recommends that all our customers take the following actions:

  1. Ensure that all active BitLocker recovery keys are saved in Active Directory and/or CapaInstaller
