With the release of Windows 11, Microsoft introduced a new, sleek, and modern operating system. However, one of the key requirements for Windows 11 is a compatible CPU with TPM 2.0 and Secure Boot support. This has left some users with older hardware wondering if they can still enjoy the benefits of Windows 11. The good news is that there are ways to install Windows 11 on unsupported CPUs. In this article, we’ll walk you through the steps to make it happen.

Disclaimer: Installing Windows 11 on unsupported hardware may not provide the best user experience, and you might encounter compatibility issues or performance limitations. Proceed at your own risk.


Before you begin the installation process, you’ll need a few things:

  1. A USB flash drive (at least 8GB) for creating a bootable installation media.
  2. A Windows 11 ISO file. You can download this from a trusted source, such as the official Microsoft website.
  3. A computer with a CPU that doesn’t meet the official Windows 11 requirements but still meets some minimum system requirements, including 64-bit architecture.

Step-by-Step Guide

  1. Back Up Your Data: Before making any changes to your system, ensure that you’ve backed up all your important data. This is a crucial step to avoid data loss during the installation process.
  2. Check BIOS Settings:
  • Boot your computer and enter the BIOS settings. You can usually do this by pressing a key like F2, F12, or Delete during startup.
  • Ensure that Secure Boot is turned off.
  • If TPM 2.0 is causing issues, check if you can disable it in the BIOS. Not all systems allow this, but it’s worth a try.
  1. Create a Bootable USB Drive:
  • Download a tool like Rufus and use it to create a bootable USB drive from the Windows 11 ISO file.
  • Insert the USB drive into your computer.
  1. Begin the Installation:
  • Restart your computer with the bootable USB drive inserted.
  • Boot from the USB drive by selecting it from the boot menu (usually accessible by pressing a specific key during startup).
  • Follow the on-screen prompts to begin the Windows 11 installation process.
  1. Skip Product Key Entry:
  • During the installation process, you may be prompted to enter a product key. You can choose to skip this step for now. Windows 11 can be used without a product key, but it will have certain limitations.
  1. Choose Custom Installation:
  • Select the “Custom” option when prompted, which allows you to choose the installation location.
  1. Install Windows 11:
  • Choose the partition or drive where you want to install Windows 11. Be cautious not to delete or format partitions with important data.
  1. Complete the Installation:
  • Follow the on-screen instructions to complete the installation process. This may take some time, so be patient.
  1. Install Necessary Drivers:
  • After the installation is complete, you may need to manually install drivers for your hardware components, especially if Windows 11 doesn’t automatically recognize them.
  1. Activate Windows:
    • While you can use Windows 11 without activation, you may want to purchase a legitimate product key to fully activate and unlock all features.


Installing Windows 11 on unsupported CPUs is possible, but it requires some technical knowledge and patience. Keep in mind that performance and compatibility issues may arise, so it’s essential to consider the pros and cons before proceeding. If your hardware doesn’t meet the official requirements, you can still enjoy Windows 10 or other alternative operating systems that may be better suited to your system’s capabilities.
