Microsoft's Windows 11 24H2 update enables BitLocker (Device Encryption) by default, encrypting the entire drive to protect user data. BitLocker is automatically activated during a clean installation when users sign in with a Microsoft account, and manufacturers will have it enabled by default on new PCs with this version. Microsoft has relaxed certain hardware requirements to increase accessibility. Users have reported being locked out of their PCs due to a lack of communication about BitLocker's activation process. The BitLocker recovery key can be found by signing into the Microsoft account linked to the PC at account.microsoft.com/devices/recoverykey. To disable BitLocker, Windows 11 Home users can go to Settings > Privacy & Security > Device Encryption, while Pro users can search for Manage BitLocker in the Start menu. To prevent automatic BitLocker encryption during installation, users can modify settings in the Registry Editor.
