How to fix 'This device cannot use a Trusted Platform Module' error on Windows.
If you're encountering the "This device cannot use a Trusted Platform Module" error on Windows, it could be due to various reasons
If you use Microsoft's Bitlocker data encryption feature to encrypt your hard drive or USB on Windows and you receive the error message above after setting up BitLocker. This means that your computer does not have a TPM chip (Trusted Platform Module).
Here's a step-by-step guide to troubleshoot and potentially fix this issue:
Check TPM Compatibility: Ensure that your device's hardware supports Trusted Platform Module (TPM). TPM is a hardware-based security feature, and not all devices come with it.
Enable TPM in BIOS/UEFI: If your device supports TPM but it's disabled in BIOS/UEFI settings, you need to enable it. Restart your computer and enter BIOS/UEFI settings by pressing a specific key (usually F2, F10, or Del) during startup. Look for TPM settings and enable it if it's disabled. Save changes and exit BIOS/UEFI.
Update BIOS/UEFI Firmware: Sometimes, outdated firmware can cause compatibility issues with TPM. Check your device manufacturer's website for BIOS/UEFI updates and install the latest version.
Clear TPM: If TPM was previously enabled but you're still encountering the error, try clearing the TPM.
- Press Win + R to open the Run dialog, then type
tpm.msc
and press Enter to open the TPM Management console. - In the console, click on "Clear TPM" option from the right-hand side panel. Next, Follow the on-screen instructions to clear the TPM.
- Press Win + R to open the Run dialog, then type
Check TPM Services: Ensure that TPM-related services are running properly. To do this:
- Press Win + R to open the Run dialog, then type
services.msc
and press Enter to open the Services console. - Look for services like "Trusted Platform Module" or "TPM Base Services". Make sure they are set to "Automatic" startup type and are running. If not, right-click on the service, select Properties, set Startup type to Automatic, and start the service.
- Press Win + R to open the Run dialog, then type
Update Windows: Ensure that your Windows operating system is up-to-date. Sometimes, Microsoft releases updates to address compatibility issues and bugs related to TPM.
Driver Updates: Make sure all drivers on your system, especially chipset drivers, are up-to-date. Visit your device manufacturer's website or use Windows Update to check for driver updates.
Check for Malware: Sometimes, malware or viruses can interfere with TPM functionality. Run a full system scan using your preferred antivirus software to ensure your system is clean.
Contact Manufacturer Support: If none of the above steps resolve the issue, it's possible there's a hardware problem with your TPM module. Contact your device manufacturer's support for further assistance or to inquire about warranty options.
Another way you can use Group Policy Editor to fix "This device cannot use a Trusted Platform Module".
