Microsoft Hands FBI First-Ever BitLocker Keys in Guam Fraud Probe

Focusing Facts

  1. Microsoft says it receives about 20 BitLocker key requests each year but can only comply when users’ keys are stored in its cloud.
  2. Court filings in the Guam pandemic-unemployment fraud case show the laptops were confiscated in Aug 2024 and decrypted after Microsoft delivered the keys on 10 Feb 2025.
  3. Because Windows 11 forces sign-in with a Microsoft account, the OS by default uploads BitLocker keys to Microsoft’s servers unless users manually opt out.
