In this article, we will show you how to install windows 11 on an unsupported CPU. Because if you have a PC older than an 8th gen Intel product and an older TPM solution, you might encounter issues installing windows 11 to your rig.

Luckily, there is a way to install this Windows 11 into unsupported CPUs, and, as it turns out, a way that is approved by Microsoft. Here’s the step-by-step guide on How to install windows 11 on an unsupported CPU.

Windows 11 on unsupported CPU – guide



Download the Windows ISO

Download the Windows 11 ISO from the Microsoft website.

To do this, open your browser and go to the Microsoft website. Scroll down to the “Download Windows 11 disk image (ISO)” section and select the “Windows 11 multi-edition ISO” from the drop-down menu.

Click on the blue “Download” button, then select your preferred language and click the “Confirm” button. Finally, click on the blue “64-bit download” button and choose a location to save the file on your desktop.



Bypass the CPU check

You’ll need to edit the Windows registry. To do this, press the Windows button and type “Registry editor” into the search bar.

Select “Registry Editor” from the search results.

Navigate to the following location: HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup.

Right-click on an empty space on the right side of the window, hover over “New,” and select “DWORD (32-bit) Value.”

Rename this value “AllowUpgradesWithUnsupportedTPMOrCPU” Double-click on the key and change the “Value data” to “1.” Save the changes and restart your PC.



Open the ISO

Now, open the ISO file in Windows explorer and launch the setup.

To do this, right-click on the ISO file and select “Mount.” A new virtual drive will appear on your PC. Double-click on the “setup.exe” file to start the installation process.

Keep in mind that Microsoft has stated that following this workaround may result in not receiving future security updates, so it is important to carefully consider whether this is the right decision for your specific situation. Also, be very careful when renaming the folder; copy-paste the name exactly as found here.

Final thoughts

Installing Windows 11 on an unsupported CPU isn’t particularly hard, but if you’re not confident – or comfortable changing your registry – then there are other options. These may include a new build and new CPU for Windows 11 use.

Or you could ask someone you trust to carry out the necessary changes for you. So you can get on with using Windows 11 as you intended.
