Microsoft has revealed that after the release of October 2025 Windows updates, some systems might unexpectedly boot into BitLocker recovery mode. This typically happens when hardware changes or updates to the Trusted Platform Module (TPM) occur, as BitLocker protects data by encrypting storage drives. Users facing this issue will need their recovery key to regain access.
The problem mainly affects Intel systems equipped with Connected Standby—these devices can maintain a network connection even in low-power mode. Microsoft stated, “After installing Windows Updates released on or after October 14, 2025, some devices might encounter issues during restart or startup.” Once users enter their recovery key, systems should start normally without further prompts.
### Scope of Affected Systems
The impacted systems include Windows 11 versions 24H2 and 25H2, as well as Windows 10 version 22H2. Additionally, IT administrators can mitigate the situation using a group policy through Known Issue Rollback (KIR) but will need to consult Microsoft Support for further guidance.
In May, Microsoft had released emergency updates to fix a similar issue where BitLocker recovery prompts were triggered following Windows 10 updates. Last year, in August, the company also responded to issues involving BitLocker after users installed the July 2024 updates.
– Windows 11 24H2 affected
– Windows 11 25H2 affected
– Windows 10 22H2 affected
– Connected Standby causes issues
– Recovery key required for access
– Similar issues date back to 2022
### Previous BitLocker Issues Recap
These aren’t isolated incidents; Microsoft has encountered multiple reports about BitLocker recovery prompts tied to updates. In August 2022, for instance, an update led to similar behavior, and in May 2025, another wave of reports prompted quick action. This history underscores the ongoing challenges with BitLocker prompts after updates.
