How to Install Windows 11 on Unsupported Processor: Step-by-Step Guide

If you’re itching to get Windows 11 on your computer but your processor isn’t officially supported, don’t worry—there’s a way to do it. The process involves bypassing some of Microsoft’s system checks and making a few tweaks to your installation files.

How to Install Windows 11 on Unsupported Processor

In this guide, I’ll walk you through the steps to install Windows 11 on a computer with an unsupported processor. By following these instructions, you’ll be able to bypass the hardware check and successfully install Windows 11.

Step 1: Download the Windows 11 ISO File

First, download the Windows 11 ISO file from the official Microsoft website.

Once you’ve downloaded the ISO file, save it to a location on your computer where you can easily find it. This file contains all the installation data for Windows 11.

Step 2: Create a Bootable USB Drive

Next, create a bootable USB drive using a tool like Rufus.

Rufus is a free tool that helps you create a bootable USB drive. Open Rufus, select the Windows 11 ISO file, and follow the prompts to make your USB drive bootable.

Step 3: Modify the Registry

Now, you’ll need to modify the registry to bypass the CPU check.

Boot your computer from the USB drive. When the Windows Setup screen appears, press Shift + F10 to open a command prompt. Type regedit to open the Registry Editor. Navigate to HKEY_LOCAL_MACHINESYSTEMSetup and create a new key named LabConfig. Then, create DWORD values named BypassTPMCheck, BypassRAMCheck, and BypassSecureBootCheck, setting each value to 1.

Step 4: Begin Installation

After modifying the registry, start the installation process by selecting "Install Now."

Follow the on-screen prompts. You’ll be asked to select your language, time, and keyboard preferences, then click "Next" and "Install Now." This begins the Windows 11 installation process.

Step 5: Follow the Setup Instructions

Continue following the setup instructions provided by the Windows installer.

You’ll need to accept the license terms and choose the type of installation you want. Select "Custom" to install Windows 11 on a specific partition. Choose the partition where you want to install Windows 11 and click "Next."

After completing these steps, your computer will restart, and Windows 11 will begin to install. This process might take some time, so be patient.
