Almost all modern computers, Intel or AMD processing chips, have built-in TPM and Secure Boot features. In case your device is new and supports both TPM and Secure Boot, make sure they are enabled.

Trusted Platform Module (TPM)

Used in all Windows devices since 2016, Trusted Platform Module (TPM) is a microchip that is available in virtual or firmware variants. The most recent version of TPM 2.0 is paramount for Windows 11 upgrade. It acts like a building block for security upgrades like Windows Hello, used for identity protection, and BitLocker for data protection. Although your system is capable of running TPM 2.0, it still needs manual enabling. If you are wondering how to check for TPM on your computer or laptop, press Windows button along with R key and type tpm.msc to select OK.

If your PC doesn't have a TPM 2.0 chip, no option will appear on your screen after the given command. So either you have to install Windows 11 without TPM or purchase a TMP 2.0 chip from a known computer hardware retailer. Here's a peek at the steps to enable TPM 2.0 on your computer:

  • In the TPM screen, make sure the value of the Specification Version is 2.0. If not, you will get an error message due to the incompatible TPM. It means, either the TPM chip is unavailable on your computer's motherboard or it is disabled in BIOS.

Note: Most PCs respond if you press Function (F) key or Del key right before the Windows boot. However, for a different manufacturer, you must refer to your system's manual.

  • After pressing the desired keys, go to the Advanced options on your BIOS and look for TPM Support option to enable it.
  • Save and exit BIOS by pressing the F10 key.

Secure Boot

It's a built-in feature in your computer that decides whether your system needs an OS upgrade. The feature helps prevent any invasive malware attack and Windows Piracy, which is an illegal practice of downloading and activating Windows OS update without a license. To enable Secure Boot, you need to switch your PC's boot mode on from legacy BIOS to UEFI/BIOS. Here's how to do it:

  • Press Windows key and click on the Settings icon on the left side of the menu.
  • In the Settings window, click on Update & Security followed by Recovery on the left pane. Under the Advanced startup header, click on the Restart button to restart your system.
  • At this point, instead of the regular desktop screen, a blue screen will appear with a couple of options.
  • Click on Troubleshoot, followed by Advanced options and UEFI Firmware Settings.
  • As you enter the UEFI settings, search for the Secure Boot setting. It may appear under any tab- Boot, Security, or Authentication.
  • If you manage to find the Secure Boot setting, click on Secure Boot to enable it.
  • Save the changes and exit UEFI menu. Once you do that, your computer will automatically reboot, and your regular Windows desktop will appear.
