Microsoft confirmed a bug in the October 2025 Update is causing BitLocker recovery on reboot.
This issue affects Windows 11 25H2, 24H2 and even Windows 10. Mostly, business users are affected.
If you don't have the BitLocker recovery key (always accessible via Microsoft account), you could be locked out of your PC.
BitLocker protects your data by encrypting drives, and recovery usually appears after hardware or TPM changes.
Microsoft says this bug mostly hits Intel PCs with Modern Standby (the feature that keeps the PC online in low power).
Recently, Microsoft also broke Windows 11 Task Manager, causing duplicate processes and performance issues in some cases.
