How to Install Windows 11 on an Unsupported PC

This section will guide you through the necessary steps to install Windows 11 on a PC that doesn’t meet the official system requirements. The process includes downloading the installation files, creating a bootable USB, and modifying some settings to bypass the requirements.

Step 1: Download the Windows 11 ISO File

First, you need to download the official Windows 11 ISO file from Microsoft’s website.

Visit the Microsoft website and look for the Windows 11 download section. Choose “Download ISO” and select the language and edition you prefer. Make sure to save the file in an easily accessible location on your current PC.

Step 2: Create a Bootable USB Drive

Next, you need a bootable USB drive with the Windows 11 ISO file.

Use a tool like Rufus to create the bootable USB drive. Open Rufus, select your USB drive, and choose the Windows 11 ISO file you downloaded. Start the process and wait for it to complete.

Step 3: Modify Registry to Bypass Requirements

Before you can install Windows 11, you need to modify the registry settings to bypass the system requirements.

Press Win + R to open the Run dialog, type regedit, and press Enter. Navigate to HKEY_LOCAL_MACHINESYSTEMSetupMoSetup. Right-click, select New > DWORD (32-bit) Value, and name it AllowUpgradesWithUnsupportedTPMOrCPU. Set its value to 1.

Step 4: Boot from the USB Drive

Now, you need to restart your PC and boot from the USB drive.

Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, F12, Delete, or Esc). Change the boot order to prioritize the USB drive, save the settings, and exit.

Step 5: Install Windows 11

Finally, follow the on-screen instructions to install Windows 11.

Once you boot from the USB, the Windows 11 installation process will begin. Follow the prompts to install Windows 11, selecting “Custom Installation” if you’re upgrading from an older version.

After completing these steps, your unsupported PC will be running Windows 11, allowing you to enjoy all the new features and updates.
