How to Fix your PC if it Can’t Run Windows 11

Needless to say, you’ll need to solve the three defects highlighted above to enable your PC to run Windows 11.

Here’s how:

Inaccurate Report by Health Check App

According to the details of a Microsoft official document, your PC must have multiple levels of hardware to operate the new OS – “Soft Floor” and “Hard Floor.”

The Health Check app checks your PC’s compatibility against the Second-floor hardware requirement, implying that your machine needs to run on TPM 2.0 and 8th Gen Intel & Ryzen 2000 series processors.

In reality, however, you can still install Windows 11 on PCs running on a 64-bit dual-core processor with a 1GHZ clock speed. So, there’s a likelihood that the “your PC can’t run Windows 11” error could be because of incorrect analysis by the Health Check app.

Microsoft has said it’s aware of the problem already and is working to resolve it by updating the Health Check app.

What can you do? Well, wait for the update. Meanwhile, you can down the updated app of Windows 11 page and check-mark the ‘check for compatibility” tab.

Disabled TPM

For starters, TPM (Trusted Platform Module) is a security chip that provides hardware-based, security-related functions. TPM has been a standard since 2016, and it’s likely your PC has it already.

In fact, computers manufactured during the last couple of years come with TPM 2.0. You can check if your machine has a compatible TPM by running the get-tpm command in the PowerShell window. Here’s how:

1. On the Start menu, search for Windows PowerShell

2. Right-click on Windows PowerShell. Click on Run as Administrator

3. Allow the window to open. Type and enter get-tpm

4. Check if your PC has TPM and whether it’s enabled or not

5. You can also check if your computer has TPM by pressing Win + R, type tpm.MSC and press enter. Wait for the TPM Management window to open. Then check the “status” of your PC’s “TPM Specification Version.”

How to Enable the TPM

If your PC’s TMP is disabled, you’ll need to open the BIOS menu and enable it manually.

Here’s how.

1. Start by shutting down your computer

2. Reboot your machine and during start-up, open the BIOS or UEFI menu. You can do this by pressing F1, F2, F10, F11, and DEL.

3. Note – the keys may vary depending on the manufacturer – so be sure to refer to the user manual or manufacturer’s website for accurate info.

4. Allow the BIOS or UEFI menu to open and tap the Security option

5. Look for TPM and check whether it’s enabled. Enable it if it’s not.

6. Once you’ve enabled the TPM. Save and Exit. Restart your computer.

Disabled Secure Boot

Secure Boot is a security standard designed to ensure your PC boosts using software a manufacturer trusts. That way, your machine is safe from malware. Secure Boot is a standard in all PCs.

1. Your devices must Secure Boot to be compatible with Windows 11.

2. How to Check if Secure Boot is Enabled in Your PC

3. To check the status of your computer’s Secure Boot, you’ll need to do the following:

4. Press Window +R. That opens the Run window

5. Type and enter msinfo32

6. Allow the window to open and look for “Secure Boot State.”
