Windows 11 users need to note this to avoid losing data due to Microsoft's new changes.
Microsoft will enable BitLocker encryption by default on all devices with Windows 11 24H2 installed, including new installs and reinstalls. Although this feature helps secure data, it also poses a risk of data loss if users are not careful.
Starting with Windows 11 24H2, Microsoft will automatically enable BitLocker encryption during the installation or reinstallation of the operating system. This applies to both Windows 11 Pro and Home. In particular, not only partition C is encrypted, but all other partitions connected to the machine will also be encrypted during the reinstallation process.
BitLocker encryption will be enabled by default starting with Windows 11 24H2.
For Windows 11 Home, BitLocker encryption is only applied if the device manufacturer enabled encryption in UEFI. Therefore, computers that build their own configuration may not be affected.
While BitLocker encryption helps protect data, it can also lead to data loss if users are not careful. If a BitLocker encrypted drive becomes corrupted or a user forgets their recovery password, they could lose access to all data on the drive.
Users can also turn off BitLocker manually during the installation process or reinstall Windows 11 to avoid data loss. However, Microsoft also recommends that users back up data before turning off BitLocker.
