If you are trying to encrypt your C drive with BitLocker on Windows 10 and receiving an error message that says “BitLocker cannot be used because the TPM is not compatible with the version of BitLocker Drive Encryption,” it means that your computer does not have a compatible TPM (Trusted Platform Module) chip installed. However, you can still use BitLocker to encrypt your C drive by following the steps below:
1. Open the Group Policy Editor by pressing the Windows key + R, typing “gpedit.msc” in the Run dialog box, and pressing Enter.
2. In the Group Policy Editor, navigate to Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.
3. Double-click on “Require additional authentication at startup” policy and select “Enabled.”
4. Check the box next to “Allow BitLocker without a compatible TPM” and click “OK.”
5. Close the Group Policy Editor and restart your computer.
6. Once your computer has restarted, open the BitLocker Drive Encryption wizard by right-clicking on your C drive in File Explorer, selecting “Turn on BitLocker,” and following the prompts.
7. Choose the encryption method you want to use and create a strong password or insert a USB flash drive to use as a startup key.
8. Click “Next” and choose whether to encrypt only the used disk space or the entire drive.
9. Click “Next” and choose whether to save or print the recovery key.
10. Click “Next” and choose whether to run a system check or skip it.
11. Click “Start encrypting” and wait for the encryption process to complete.
By following these steps, you can encrypt your C drive with BitLocker even if your computer does not have a compatible TPM chip installed. However, keep in mind that using BitLocker without a TPM may reduce the security of your system, as it allows for the possibility of a boot-time attack. Therefore, it is recommended to use a compatible TPM chip if possible.
Conclusion
In conclusion, while it may be frustrating to receive the “BitLocker cannot be used because the TPM is not compatible” error message, there is a solution that allows you to still encrypt your C drive with BitLocker. By following the steps outlined above, you can enable BitLocker without a compatible TPM and protect your sensitive data. However, it is important to keep in mind the potential security risks of using BitLocker without a TPM and consider upgrading to a compatible TPM chip if possible.
