Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

Full-volume encryption using BitLocker Drive Encryption is vital for protecting data and system integrity on devices running the Windows 8.1, Windows 8, or Windows 7 operating system. It is equally important to protect the BitLocker encryption key. On Windows 7 devices, sufficiently protecting that key often required pre-boot authentication, which many users find inconvenient and complicates device management. Microsoft has made improvements in Windows 8.1 and worked closely with hardware manufacturers to deliver Windows 8.1 and Windows 8 devices that are fundamentally resistant to known attacks against the BitLocker encryption key. As a result, many organizations can now meet their security requirements without using pre-boot authentication, reducing complexity and inconvenience. This guide provides detailed information that will help you understand the circumstances under which the use of pre-boot authentication is recommended and when it can be safely omitted from a device’s configuration.
