How to Enable BitLocker Drive Encryption in Windows

Step by step

1. 1 min

   Open the BitLocker Drive Encryption control panel

   Open the Start menu, type 'Manage BitLocker', and press Enter. If you do not see this option, ensure your version of Windows supports BitLocker, as it is not available on Windows Home editions.

   Note: If you are on Windows Home, you must upgrade to Pro to access this feature.
2. 30 sec

   Turn on BitLocker for the system drive

   Locate the Operating System drive (usually C:) under the BitLocker Drive Encryption section. Click the 'Turn on BitLocker' link to initiate the setup wizard.

3. 1 min

   Choose a backup method for your recovery key

   The wizard will prompt you to back up your recovery key. Select 'Save to your Microsoft account', 'Save to a file', or 'Print the recovery key'. This key is critical for regaining access to your files if your authentication fails.

   Note: Store your recovery key in a secure, offline location. Never store it on the drive you are encrypting.

   Choose how much of your drive to encrypt

   Select 'Encrypt used disk space only' for new PCs or 'Encrypt entire drive' for PCs that have been in use for a long time. Encrypting the entire drive is slower but more secure.

5. 30 sec

   Select the encryption mode

   Choose 'New encryption mode' if you are sure this drive will only be used on Windows 10 (version 1511) or later. Select 'Compatible mode' if you intend to move the drive between devices running older versions of Windows.

6. 2 min

   Start the encryption process

   Check the box labeled 'Run BitLocker system check' and click 'Continue'. Restart your computer when prompted to complete the encryption process. Windows will encrypt your drive in the background.

   Note: Your computer remains usable during the encryption process, though you may notice a slight drop in performance.
