Then check the “Open Windows PC Health Check” box and select “Finish.”

You’ll see a Windows 11 section at the top of the app. Select the blue “Check Now” button.

If your PC is compatible, a window will open saying that “This PC meets Windows 11 requirements.”

If your PC isn’t officially supported, a window will open saying that your PC doesn’t currently meet Windows 11 system requirements.

The tool will also tell you why and provide you with links to more information. For example, if it says the problem is only that TPM 2.0 is not enabled, you may be able to enable TPM from within your computer’s UEFI firmware, which is the modern alternative to the BIOS. If Secure Boot isn’t currently enabled, you may be able to enable it.

There is also a helpful “Device specifications” button that links to a web page with more information about the system requirements. If your PC isn’t officially compatible, you will be able to upgrade to Windows 11 anyway, but you may run into bugs and Microsoft says there’s no guarantee your PC will continue to receive security updates.
