What is BitLocker and how does it work?
BitLocker is a built-in disk encryption feature in Windows that helps protect data on your hard drives by encrypting the entire volume. It uses the Trusted Platform Module (TPM) hardware to store cryptographic keys securely, ensuring that only authorized users can access the data. When you enable BitLocker, it encrypts your files, making them unreadable without the correct authentication, such as a password or a recovery key.
The encryption process runs in the background while you use your computer, so it does not interfere with the normal functioning of your system. Once enabled, you can access your files as usual, but if there are any unauthorized access attempts, BitLocker will require you to provide the necessary credentials, adding an extra layer of security to your sensitive information.
Why is my BitLocker not turning on?
If you’re having trouble with BitLocker not activating, there could be several reasons for this issue. One common cause is that your device may not have a compatible version of Windows or the required hardware components that support BitLocker. For BitLocker to function, you generally need to have a professional or enterprise version of Windows, along with a TPM chip, which handles the secure storage of the encryption keys.
Another reason could be that BitLocker has not been enabled in the system settings or the Group Policy settings are preventing its activation. It’s crucial to check whether your device meets these prerequisites and to ensure that BitLocker is properly set up in your system settings before attempting to turn it on.
