To enable TPM 2.0 on a computer running Windows 11, follow these steps:
Press the Windows key + R to open the Run dialog, then type "tpm.msc" and press Enter. This will open the TPM Management console.
In the TPM Management console, click on "Action" in the menu bar and then click "Turn TPM On".
If the TPM is already enabled, you will see a message stating that the TPM is already turned on. If the TPM is not enabled, you will see a message prompting you to turn on the TPM. Click "Yes" to enable the TPM.
You may be prompted to enter your BitLocker recovery key. This key is used to encrypt the data on your hard drive, so it is important to keep it in a safe place.
After you have entered your recovery key, the TPM will be enabled and you will see a message stating that the TPM is ready for use.
Note: If you do not see the TPM Management console or the option to turn on the TPM, it is possible that your computer does not have a TPM chip installed. In this case, you will need to check with the manufacturer or consult the documentation for your computer to determine if a TPM chip can be added.
