Understanding TPM 2.0 Requirements

TPM 2.0 chip

TPM 2.0 (Trusted Platform Module) is a hardware component that provides enhanced security features for your computer. Windows 11 requires TPM 2.0 to ensure a secure operating system environment. If you encounter the “Windows 11 Processor Not Supported” error, it may be due to your system not meeting the TPM 2.0 requirement. Here’s what you need to know:

1. Check TPM support in BIOS: Restart your computer and access the BIOS settings by pressing the appropriate key during startup (usually Del, F2, or F10). Look for a section related to security or TPM. Ensure that TPM is enabled and set to version 2.0.

2. Enable TPM in Windows Registry: Press Windows key + R to open the Run dialog box. Type “regedit” and press Enter to open the Windows Registry Editor. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\TPM. If the TPM key is not present, create it. Then, create a DWORD value named “OSEnabled” and set its value to 1.

3. Update Windows: Ensure that your copy of Windows is up to date by checking for and installing any available updates. Open the Settings app, go to “Update & Security,” and click on “Windows Update.” Select “Check for updates” and install any pending updates.

4. Consult your hardware manufacturer: If your system does not support TPM 2.0, you may need to upgrade your hardware. Contact your computer manufacturer or check their website for information on compatible TPM modules or motherboard upgrades.

5. Consider professional assistance: If you’re uncomfortable performing these steps yourself, it’s recommended to seek professional assistance from a certified technician.
