BitLocker is a feature embedded since Windows Vista that allows you to encrypt your hard disk. You should enable this feature to prevent unauthorized access to your private data in case your laptop or computer gets stolen. Another advantage is the integration with TPM (Trusted Platform Module) which validates the integrity of your boot and system files before decrypting your data.
BitLocker is only available for:
- Computers with TPM 1.2 or later (Or use an external Drive to store the startup key)
- Supported BIOS / UEFI
- Boot drive with NTFS file system
- System drive with FAT32 (UEFI) or NTFS (BIOS) file system
If your device is not supported, you will see the following message.
If that's the case, you can buy a TPM Module I, for example, use the following Asus TPM Module, but be aware that your mainboard must have a TPM header.
After installing the module open again the Settings Dialog and follow the instructions after clicking "Turn on BitLocker".
