With every new version of Windows comes a pressing question. Will your computer be able to run it? That’s certainly the case with Windows 11, which Microsoft unveiled last week complete with design changes, Start menu and taskbar tweaks, widgets, snap layouts, Microsoft Teams chatting and support for Android apps.

The good news is that Windows 11 will be available as a free update for existing Windows 10 computers. The new version will officially pop up sometime around the holiday season, though only for new PCs. The rollout of Windows 11 for Windows 10 computers won’t begin until 2022 and will stretch through the first half of the year.

Whatever the timeframe, you might like to know if your current Windows 10 computer is capable of supporting Windows 11. And for that, Microsoft offers a few resources.

Minimum system requirements

First, Microsoft has published the minimum system requirements for Windows 11 as follows:

  • Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC).
  • Memory: 4 GB RAM.
  • Storage: 64 GB or larger storage device.
  • System firmware: UEFI, Secure Boot capable.
  • TPM: Trusted Platform Module (TPM) version 2.0.
  • Graphics card: DirectX 12 compatible graphics/WDDM 2.x.
  • Display: Greater than 9 inches with HD Resolution (720p).
  • Internet connection: Microsoft account and internet connectivity required for setup of Windows 11 Home.

PC Health Check app

To help you determine if your Windows 10 computer meets the requirements to run Windows 11, Microsoft also provides a free PC Health Check tool. To download this app, browse to Microsoft’s Introducing Windows 11 page, scroll down to the Get ready section, and click the Download app link under Check for compatibility. Save and run the WindowsPCHealthCheckSetup.msi file. Open the program and click the Check now button (Figure A).

If your computer passes the test, a message appears telling you that “This PC can run Windows 11.” If not, it could mean that your PC doesn’t meet all the minimum requirements, which leads us to the TPM issue (Figure B).

Trusted Platform Module

Beyond the required processor, memory, storage and other hardware, your computer also needs to be running version 2.0 of the Trusted Platform Module. The TPM is a chip built into your motherboard or CPU to protect encryption keys, user credentials and other sensitive information against malicious software. Working on a hardware level, TPM is designed to secure your data against ransomware and other threats. A Microsoft blog post explains more about TPM and why it’s required on today’s Windows PCs.

Most computers from the past few years should have a TPM chip. If your computer is relatively recent, and the PC Health Check tool tells you that it can’t run Window 11 due to the TPM 2.0 requirement, here are some steps to take.

In the Windows 10 search field, type tpm.msc. The resulting screen will confirm whether or not a compatible TPM has been found and enabled (Figure C).

Next, you need to check your BIOS. Reboot your computer and press the appropriate key to access your BIOS. At the BIOS screen, look for and open a setting for Security. If the TPM chip type says TPM 2.0, then all you should need to do is enable the chip. If the chip type is an older version, such as 1.2, check the Downloads page for your PC manufacturer to see if a BIOS update is available. If so, that might upgrade your TPM to 2.0. If not, then your PC may simply be too old or incapable of supporting the newer TPM chip type and therefore unable to run Windows 11.
