One of the core requirements for installing or upgrading to Windows 11 is that your PC has Trusted Platform Module (TPM) chip, specifically version 2 upwards. If your PC’s processor doesn’t have TPM 2.0, you won’t be able to install Windows 11 – you will have to buy a new PC that supports TPM 2.0.
However, if you have a PC that supports Intel Platform Trust Technology (PTT), which is a low-cost version of the TPM and does basically the same thing, you should be fine – I have tested this. If TPM or PTT is not enabled, you would simply need to enable it in the BIOS – they are normally found under the Security section in the BIOS.
To check if your PC supports TPM, simply do the following:
1. Press Windows + R to launch the Run program
2. Type ‘tpm.msc‘and click OK or press Enter
3. Look for confirmation or a “Compatible TPM cannot be found” error.
4. If you get Compatible TPM cannot be found, it doesn’t necessarily mean that your PC doesn’t support TPM – it could mean that it is disabled and you need to enable it.
Note: You will need to check your PC manufacturer’s website to learn how to enable TPM or PTT if you don’t already know.
