After seeing multiple users lose all their data because of BitLocker after Windows 11 system changes, I wanted to discuss this: Microsoft now automatically enables BitLocker during onboarding when signing into a Microsoft Account. Lose access to your MS account = lose your data forever. No warnings, no second chances. Many people learn about BitLocker the first time it locks them out. ... I'd argue that for the average user, Availability of their data matters far more than confidentiality. Losing access to family photos and documents because of inavailability is far more painful than any confidentiality concerns. Without mandatory, redundant key backups, BitLocker isn't securing anything — it's just silently setting users up for catastrophic failure. I've seen this happen too often now. Microsoft's "secure by default" approach has become the biggest risk to personal data on Windows 11, completely overlooking the real needs of everyday users.
