How to Use BitLocker Encryption Without a TPM in Windows 10
In this post, we will learn the steps to enable BitLocker Drive Encryption (BDE) on Windows 10 without TPM (Trusted Platform Module).
What is BitLocker Drive Encryption?
BitLocker is a data protection feature that encrypts any drives on your computer to help prevent data theft or exposure. BitLocker requires a TPM (Trusted Platform Module) chip on your computer’s motherboard.
TPM chip generates and stores the actual encryption keys. TPM can automatically unlock your PC’s drive when it boots so you can sign in just by typing your username and password.
You can use BitLocker Drive Encryption without the TPM chip, but it requires some extra steps for additional authentication.
- BitLocker Drive Encryption is available only on Pro and Enterprise edition of Windows 10.
- BitLocker Drive Encryption a time-consuming process.
- Take a full backup before starting the BDE process.
How to Turn On BitLocker Without a TPM in Windows 10:

14. Enter a strong password that you’ll use to unlock the encrypted drive. Click Next.
Backup BitLocker Recovery Key:
The Recovery Key is useful in case you forget your encryption password. Now you need to save your BitLocker Recovery Key somewhere safe by selecting one of the given options.
- Option:1 Save to your Microsoft account
- Option:2 Save to a USB flash drive
- Option:3 Save to a file
- Option:4 Print the recovery
15. Select the option that is most suitable for you, and save the recovery key in a safe place. After that, click the Next button.
You now see the option to choose how much of your drive to encrypt.
- Encrypt used disk space only (faster and best for new PCs and drives)
- Encrypt entire drive (slower but best for PCs and drives already in use)
16. Select the option that is most convenient for you. I will go with encrypt used disk space as its much faster.
17. Now you have the option to choose which encryption mode you want to use. If you are running the latest version of Windows 10 then, select New encryption mode and click Next.
18. Make sure to select the Run BitLocker system check option.
19. After you click Continue, you have to restart your computer.

21. Windows 10 will normally boot up. Upon login, you will see notification about Encryption is going on.
22. On Control Panel, click System and Security. Click BitLocker Drive Encryption. You will see BitLocker is encrypting your Operating System drive.
23. You can also monitor the BitLocker Drive Encryption process using PowerShell cmdlet. Cmdlet: manage-bde -status C:
