Although Microsoft states you can run Windows 11 on systems that support at least TPM 1.2 by bypassing the check for TPM 2.0, the company strictly recommends against taking that route.

How to Check Windows 11 Compatibility

Not everyone knows what hardware they have inside their computers. Thankfully, Microsoft offers a convenient tool to check if your PC meets Windows 11's minimum requirements.

1. Download and install the new PC Health Check app from Microsoft.
2. Launch the app and click Check now at the top below the "Introducing Windows 11" message.

You'll get a pop-up on your screen that lists your hardware specifications and informs you whether they meet the minimum requirements for Windows 11.

Don't panic just yet if you find that your PC isn't compatible. Many users with modern hardware have faced this problem, but it's mostly TPM or Secure Boot-related. Both of these settings can be changed by entering the BIOS on your Windows PC.

Enabling AMD fTPM and Intel PTT

• If you have an AMD CPU, set AMD fTPM (firmware TPM) to Enabled in the Advanced menu within your system's BIOS/UEFI settings.
• If you're using an Intel CPU, you can turn on Intel PTT (Platform Trust Technology) from the same menu. Save your settings, boot up your PC, and re-check using the PC Health Check app.

Although Windows 11 has been broadly available since 2021, many users still run Windows 10 on their computers. If you know your PC supports it, now is the right time to upgrade to Windows 11, as the OS has matured since its initial launch.

However, if your PC hardware doesn't meet Windows 11's requirements, know that Microsoft will end support for Windows 10 in October 2025. After that, you'll need to upgrade to a new PC or pay Microsoft a yearly fee for extended security updates until October 2028.
