Windows 11 won’t run on your PC if it came without TPM security chip | Applications and Software

Microsoft officially unveiled Windows 11 on Thursday (24) and released the minimum specifications for it to run on your PC. Among the requirements is the TPM chip in version 2.0: without it, you will not be able to install the new system and will have to stay on Windows 10. Unfortunately, many computers do not have this security feature and are incompatible, even if they have been released or newly assembled.

What is TPM (Trusted Platform Module)?

Vivi Werneck, from the Techblog, has a PC gamer purchased nearly two years ago. Felipe Vinha, also from our team, has a gaming computer released in 2020. In both cases, the Microsoft compatibility tool says that Windows 11 cannot be installed.

The reason is the absence of the TPM (Trusted Platform Module). As Microsoft explains:

A TPM chip is a secure cryptoprocessor designed to perform cryptographic operations. It includes various physical security mechanisms to make it tamper resistant, and malicious software is unable to break its security functions.

The TPM can be a separate chip on the motherboard, integrated with another hardware component, or present in the firmware. This security feature is used to ensure the integrity of the system – that is, to know if it is performing as expected.

It also has other functions involving encryption keys, such as password protection, use of DRM for copyright protection, and software license verification.

As of July 2016, Microsoft requires PCs released to the market with Windows 10 to have TPM 2.0, but makes exceptions for computers built on demand; for custom system images (ISOs); and for models developed by the manufacturer for specific commercial purposes.

Most notebooks sold in the last decade have the TPM chip on the motherboard. However, you can’t say the same for desktops: maybe your PC has an excellent technical record and still can’t run Windows 11 because of it.

How do I know if my PC is Windows 11 compatible?

To find out if your PC is compatible with Windows 11, you need to follow these steps:

  1. download and install the PC Health Check app on the Microsoft website;
  2. open the tool and click on check now.

In the ideal scenario, you will see the warning “This computer can run Windows 11” and you can safely wait until the system launches.

However, if your PC is incompatible, the following message will appear:

This computer cannot run Windows 11

As long as this PC does not meet the system requirements to run Windows 11, you will continue to get Windows 10 updates.

There is a “Learn more” button that takes you to the list of minimum specs. However, the tool does not tell you what is missing from your PC for it to be compatible.

these are the minimum specifications:

  • 1GHz processor with two or more 64-bit cores
  • 4 GB RAM
  • 64GB of storage
  • HD screen (720p) larger than 9 inches
  • DirectX 12 or higher compatible video card or graphics chip with WDDM 2.0 driver
  • compatible with UEFI, Secure Boot, and Trusted Platform Module (TPM) in version 2.0

How do I know if my PC has TPM 2.0?

That’s easy; check out:

  1. open the start menu and type tpm;
  2. click on the option security processor;
  3. in the field Specification Version, must contain the value 2.0; otherwise, your computer does not have TPM 2.0 or does not have the feature enabled.

How to enable TPM 2.0 in BIOS?

In this case, you can check your device’s BIOS to see if there is an option to enable the TPM. Instructions may vary depending on make and model. See how to do it:

  1. on Windows 10, open the menu Start and click on On off;
  2. holding the shift key, click in Restart;
  3. on the screen that appears, follow the path Troubleshooting > Advanced Options > UEFI Firmware Settings and click on the button Restart;
  4. press key to enter BIOS Setup (can be F1, F2, F10, F11, Del – check the appropriate option on your PC screen);
  5. go to the Security tab, find the option TPM Device and choose Available;
  6. find the option TPM State and select Enabled;
  7. press the key corresponding to the command Save and Exit.
