BitLocker Bug Returns to Windows 11 & 10: Is Your Data Safe?
Recurring Windows 11 Errors: BitLocker Recovery Issue Returns and Its Impact on Users
BitLocker is a fundamental security feature in the Windows operating system, designed to protect your data by encrypting entire drives, preventing unauthorized access even if the device is lost or stolen. BitLocker uses the Advanced Encryption Standard (AES) algorithm to effectively protect data. However, Microsoft confirms that users of computers running Windows 11 and Windows 10 may encounter a new BitLocker error, which could leave them stuck in BitLocker recovery mode if they do not have their encryption key. This error particularly affects systems running Windows 11 versions (25H2 and 24H2) and Windows 10 (22H2), specifically those relying on Intel processors. This challenge comes shortly after Microsoft announced a fix for another error that was causing devices to restart unexpectedly. According to a Neowin report, October security updates for Windows 10 and Windows 11 systems may trigger BitLocker recovery mode, a recurring issue that has appeared in previous updates, including the May 2025 update.

Problem Details and the Importance of the Recovery Key
Important Tips on the BitLocker Issue
Versions of the Windows 11 operating system (25H2 and 24H2) and Windows 10 (22H2) are affected by this error. If you are a user of these versions, it is absolutely essential to keep a copy of your BitLocker recovery key. Without this key, the system will ask you to enter it to access Windows, which could lead to your device being locked and a very frustrating situation. Experts emphasize that losing a BitLocker key can lead to permanent loss of access to encrypted data (Source: ACE Data Recovery). Microsoft states that this issue primarily affects Intel devices that support "Modern Standby," a feature that allows the device to remain connected to the network in a low-power sleep mode. Although TPM (Trusted Platform Module) devices securely store encryption keys, system crashes can make these keys unavailable, necessitating the use of the recovery key. Therefore, all users are advised to be cautious and take necessary measures to avoid locking their system, specifically by ensuring the encryption key is readily available, which can be found in your Microsoft account, a printed file, on a USB drive, or through the system administrator for work environments (Source: ACE Data Recovery). Some might consider disabling BitLocker entirely given the recurring problems with this security feature.
