How to Install Windows 11 On Unsupported PCs: Minimum Requirements and Preparation

Before proceeding, it is essential to check the minimum requirements for Windows 11. Even if your PC is not officially supported, you should make sure it has at least a 64-bit processor, 4 GB of RAM and 64GB of storage space. In addition, it is recommended that you make a full backup of your data to prevent any loss. Among the minimum requirements set by Microsoft are: UEFI firmware with Secure Boot, TPM version 2.0, and a DirectX 12-compatible graphics card. These criteria exclude many devices that do not have these specifications, especially older models. There are methods to circumvent these requirements. One of the most popular is the use of media creation tools that modify Windows 11 installation files to bypass TPM and Secure Boot checks.

Downloading the Windows 11 ISO

The first step is to download the Windows 11 ISO image. Microsoft offers this option directly on its official website, thus guaranteeing the authenticity of the file. It is essential to make sure you download the most up-to-date version to avoid compatibility or security issues. Downloading the Windows 11 ISO image is a crucial step for manual installation of the operating system, especially on devices that are not automatically supported by updating via Windows Update. Microsoft makes the official ISO image available through its site, ensuring users get a reliable file free of security risks.

To proceed to download the Windows 11 ISO safely and accurately, open your browser and go to the official Windows 11 download page on Microsoft’s website. This is the first step to ensure that the downloaded file is authentic and not compromised. In the download section, you will find several options for getting Windows 11. Select the section dedicated to downloading the ISO image.

After downloading, you should check the integrity of the ISO file. You can do this by comparing the hash of the downloaded file with the hash provided by Microsoft. This step is important to make sure that the file was not damaged or altered during the download. The easiest way is to use a free tool such as VirusTotal

By following these steps, you will have a Windows 11 ISO image ready for installation. 

Creating Bootable Installation Media for Windows 11

After downloading and verifying the integrity of the Windows 11 ISO image, the next step is to create a bootable installation media. This can be accomplished through the use of a USB flash drive or DVD, although the USB option is generally preferred for its speed and convenience.

Choice of Installation Device

  • USB drive: make sure the USB drive has at least 8 GB of free space and is formatted with the NTFS or FAT32 file system. All data on it will be erased, so make a backup if necessary.
  • DVD: If you opt for a DVD, you will need a DVD burner and a blank disk. This option is less common, given the prevalence of USB drives and the declining use of DVD players in modern computers.

Using Rufus to Create the Bootable Unit

Download the latest version of Rufus from the official website. Rufus is free and reliable software that requires no installation. Start Rufus and insert the USB drive into your computer. Rufus should automatically recognize the drive. Select the Windows 11 ISO image you downloaded earlier.


In the Rufus options, choose the partition and file system that best suits your PC. For most users, the default settings are adequate, but make sure the partition type is set to GPT if your system uses UEFI, or MBR for older BIOS systems.

Once everything is configured, click “Start” to begin creating the bootable drive. This process will erase all data on the USB drive and copy the files needed to install Windows 11. The process may take some time, depending on the speed of the USB drive and your computer. Do not remove the USB drive until Rufus indicates that the process is finished. After Rufus has completed its work, it is advisable to restart the computer and try booting from the USB drive to make sure it was created correctly.

Unit Testing and Installation

To install Windows 11, you will need to boot the computer from the USB drive. This usually requires you to enter your computer’s BIOS or boot menu and select the USB drive as the first boot device. Follow the on-screen instructions to install Windows 11. If everything is set up correctly, you should see the Windows 11 installation screen.

Overcoming the TPM 2.0 Barrier to Install Windows 11

One of the major stumbling blocks encountered when installing Windows 11 on unsupported devices is the requirement for a Trusted Platform Module (TPM) version 2.0. This hardware component is used to manage encryption keys and to ensure that the system boot process is secure from external tampering. Not all PCs, especially older ones, are equipped with this technology or may have an older version of the TPM.
To bypass this verification and proceed with the installation of Windows 11, the Windows 10 registry can be worked on. The registry is a database that Windows uses to store operating system settings and options. By modifying specific registry keys, you can “trick” the Windows 11 installer into believing that TPM 2.0 is present and active.

Here are the steps for editing the registry:

  • Before making any changes, it is essential to make a backup of the registry. If there are any errors, you will be able to restore it to its previous state without compromising system stability.
  • type regedit in the Windows search bar and open the registry editor.
  • Use the sidebar to navigate to the registry key that controls the system requirements for Windows 11 installation. The exact path may vary depending on versions and configurations.
  • Once you find the correct key, you will need to modify or create values that allow you to bypass the TPM check. This usually involves creating a new DWORD value with a specific name and assigning it a datum that tells the system to bypass the TPM check.
  • after making the changes, make sure that they have been saved correctly and that the registry reflects the new configurations.
  • for the changes to take effect, you will need to restart the computer.

It is important to note that modifying the registry is a delicate operation and not officially supported by Microsoft. It should be done with caution and awareness of the risks, as an error could make the operating system unstable. In addition, although this procedure may allow the installation of Windows 11, it is not certain that the operating system will run optimally on unofficially supported hardware.

With these precautions in mind, registry editing is a solution for those who wish to experiment with Windows 11 on older hardware, while maintaining the knowledge that the best user experience is provided by devices that meet Microsoft’s official requirements.

Customizing Windows 11 ISO Image to Exceed System Requirements

When you want to install Windows 11 on hardware that does not meet the criteria imposed by Microsoft, you can work directly on the ISO image to bypass the minimum requirements checks. This process requires the use of advanced software such as PowerISO, which allows you to modify the files contained within the ISO image.

Preparing for the Modification of the ISO

Before proceeding, it is essential to make a full backup of your current system. Modifying an ISO image and installing a modified operating system carries risks, including loss of data. With this basic step done, we can download and install PowerISO. PowerISO is a tool that allows you to open, extract, burn, create, edit, compress, encrypt, split and convert ISO files, and mount ISO files with an internal virtual drive. Download the software from the official website and install it on your computer. Start PowerISO and use the “Open” option to load the Windows 11 ISO image you previously downloaded and verified.

Modifying the ISO Image

Once you open the ISO image, you will be able to see all the files and folders it contains. Navigate through these files to locate those responsible for system requirements checking. Identify the appraiserres.dll file, which is commonly associated with system requirements checking, such as TPM and CPU checking. You may need to look for specific guides online for the version of Windows 11 you are modifying, as the files and procedures may vary.

Once you locate the file, you can choose to delete it or replace it with a modified version that bypasses the checks. This step is tricky: an incorrect modification can make the Windows 11 installation unstable or not work. After making the necessary changes, save the modified ISO image. Be sure to name it so that it is clearly distinguishable from the original. Use the modified ISO file to create a bootable USB drive by following the instructions provided above.

You should double-check the integrity of the modified ISO file and, if possible, test the installation on a virtual machine before proceeding with a real device. Modifying an ISO image and installing an operating system that has been altered is not supported by Microsoft and may void the software warranty. In addition, there are security and stability risks to consider. An operating system installed from a modified ISO image may not receive official support and updates from Microsoft, which may expose the computer to security risks.
