Check How you can fix ‘This PC can’t run Windows 11’ error
Microsoft today started a rolling rollout of Windows 11. But you probably don’t have Windows 11. If you plan to download the new operating system onto your existing PC, you may have run into some roadblocks due to the system requirements for the new operating system. . (Here’s how to download Windows 11 and how to create a Windows 11 installation drive.)
If you have tried to install Windows 11 Insider Preview or use the Microsoft PC Health Check application and received an error message that said, “This PC cannot run Windows 11,” your system may not have two essential security settings enabled: Boot secure and TPM 2.0. (Here are two other things to do before downloading Windows 11.) Many modern computers and processing chips from Intel and AMD have these features built in, and now both are required for all machines running Windows 11.
Once you have downloaded the PC Health Check application, you can click Verify Now to begin the scanning process. The app will tell you if your computer supports Windows 11, or what is missing, and you can click See all results to get more information.
If your machine is new enough to support both, enabling TPM (short for Trusted Platform Module) and Secure Boot is usually pretty easy. No special skills are needed, and you will only be clicking through the menus. If you’ve never heard the words “BIOS menu” you may feel out of your element, but don’t be intimidated. With a little patience, any beginner can do this.
This is what you need to know.
What are TPM and Secure Boot?
TPM microchips are small devices known as secure cryptoprocessors. Some TPMs are virtual or firmware varieties but, like a chip, a TPM connects to your motherboard during build and is designed to enhance hardware security during computer startup. A TPM has been a mandatory piece of technology on Windows machines since 2016, so older machines may not have the necessary hardware or firmware. Previously, Microsoft required OEMs of all models built to run Windows 10 to ensure their machines were TPM 1.2 compliant. TPM 2.0 is the latest version required.
TPMs are controversial among security specialists and governments. An up-to-date and enabled TPM is a strong preventive against firmware attacks, which have steadily increased and have caught the attention of Microsoft. However, it also allows remote certification (authorized parties can see when you make certain changes to your computer) and can restrict the types of software your machine can run. TPM-equipped machines are generally not shipped to countries where Western encryption is prohibited. China uses its state-regulated alternative, TCM. In Russia, the use of TPM is only allowed with permission from the government.
Secure Boot is a feature of your computer software that controls which operating systems may be active on the machine. It’s a good and bad thing for a Windows machine. On the one hand, it can prevent certain classes of invasive malware from taking over your machine and is a central defense against ransomware.
On the other hand, it can prevent you from being able to install a second operating system on your machine, giving you two to choose from when you first turn on your computer. So if you wanted to experiment with Linux operating systems, for example, Secure Boot could stop you. Secure boot also plays an important role in preventing Windows hacking.
Some words of warning
Now that you know the safe technologies you’ll be using, there are a few things to keep in mind before diving into troubleshooting on your own.
- Microsoft confirmed that there are four types of problems that could have given you the error message “This PC cannot run Windows 11” if you used their PC Health Check tool. If you are missing the necessary hardware or firmware for Windows 11, the instructions below will not help; you will need to purchase a new device to run the operating system.
- Please note that these instructions are written as broadly as possible. This is because Windows machines vary so much that it is not feasible to cover every possible way to enable TPM and Secure Boot on all devices. However, for the most part, the process is similar enough on all machines that you should be able to use the instructions as a guide and, when your computer differs, still identify the equivalent menu or label on your own system.
- If your machine is still covered by a warranty, always talk to the manufacturer first before doing anything that could void it. If your machine is owned and maintained by your business or school, you may have unique security settings that your IT staff will need to handle. It is also a good idea to contact your local PC repair shop; Having a qualified professional on standby is the best way to get back on track if you turn around or encounter obstacles.
- Always back up your important files before making major changes to your computer. Always. Just do it. You will thank us later.
- If this is your first time working in a BIOS menu, follow the instructions and don’t stray too far off the beaten path. We’re on a very simple mission here, and nothing I recommend below will harm your machine or your data, but changing the firmware settings in your BIOS menu can have a far-reaching impact. There are few security barriers here and you can lose a lot of important data very quickly. Some mistakes can be permanent, and in most cases, there will be no pop-up windows politely asking if you are sure you want to make those mistakes.
You should definitely look around, explore your options, and become familiar with what’s under the hood, but avoid changing any settings or saving any of those changes unless you specifically know what will happen when you do.
Does my device support TPM 2.0 and Secure Boot?
If PC Health Checker suggested that TPM is not enabled, you must first find out if that is an accurate diagnosis. That’s how.
- From your desktop, press the Windows key next to spacebar + R. This will open a dialog box.
- In the text field of the box, type tpm.msc and press Enter. This should open a new window labeled “TPM Management on Local Computer”.
- Click Status. If you see a message that says “The TPM is ready to use,” the PC Health Checker has misdiagnosed it and the steps below will not help. At this point, there are a number of reasons you might be getting a wrong error message from Microsoft, so your best bet is to get a professional to take a look at your machine.
If you don’t see that message and instead see “The supported TPM cannot be found” or another message stating that the TPM may be disabled, follow the steps below.
