Windows Update on Alienware Laptops Reboots to BitLocker Recovery

The BitLocker recovery screen is displayed after the laptop reboots from running a Windows Update. The laptop does not boot until the 48-digit recovery key is entered.

For example, this issue is seen when installing the security update (KB5083769) that was released on April 14, 2026.
