How To Install Windows 11 On Unsupported Processor
This section will guide you through the steps necessary to install Windows 11 on an unsupported processor. By the end, your computer will be running the latest version, without any hiccups.
Step 1: Create a Windows 11 Bootable USB
First, you need to create a bootable USB drive containing the Windows 11 installation files.
Use the Media Creation Tool from Microsoft’s website to download Windows 11 and create a bootable USB. Ensure your USB has at least 8 GB of free space and is formatted properly.
Step 2: Modify the Registry
Next, you will need to modify the Windows registry to bypass the CPU check.
Open the Registry Editor by pressing Win + R, typing "regedit," and hitting Enter. Navigate to HKEY_LOCAL_MACHINESYSTEMSetupMoSetup. If MoSetup doesn’t exist, create it. Then, create a new DWORD (32-bit) Value named "AllowUpgradesWithUnsupportedTPMOrCPU" and set its value to 1.
Step 3: Boot From USB Drive
Now, you need to boot your computer from the USB drive.
Restart your computer and enter the BIOS/UEFI settings. Change the boot order to prioritize the USB drive. Save and exit the BIOS to boot from the USB.
Step 4: Install Windows 11
Proceed to install Windows 11 on your system.
Follow the on-screen instructions to install Windows 11. When prompted, choose "Custom: Install Windows only (advanced)" to perform a clean installation.
Step 5: Complete Setup
Finish the Windows 11 installation process.
Once the installation is complete, follow the setup prompts to configure your new Windows 11 installation, such as choosing your region, keyboard layout, and signing in with your Microsoft account.
After you follow these steps, your computer should be running Windows 11. You may need to install some updates or drivers to ensure everything runs smoothly.
