Installing Windows 11 on hardware that doesn’t meet Microsoft’s official system requirements is a topic of interest for many users who wish to explore the latest features of the operating system without upgrading their hardware. While Microsoft has set these requirements to ensure security and performance, there are several workarounds that enthusiasts and advanced users have developed. This guide consolidates various methods to bypass these restrictions, focusing on TPM, Secure Boot, and CPU requirements. However, it’s crucial to proceed with caution, understanding the potential risks and implications.

Understanding the Risks

Before attempting to install Windows 11 on unsupported hardware, consider the following:

System Stability: Bypassing official requirements may lead to unstable system performance.
Security Risks: Disabling security features like TPM can expose your system to vulnerabilities.
Update Issues: Future Windows updates may not support or may revert changes made to install on unsupported hardware.
Warranty and Support: Manufacturer support may be voided for systems running unsupported configurations.
Always back up important data before proceeding with any of the methods described below.

Method 1: Using Rufus to Create a Modified Installation Media

Rufus, a free, open-source utility, offers a straightforward way to create bootable USB drives that bypass certain Windows 11 installation checks:

  1. Download Rufus from the official site.
  2. Download the Windows 11 ISO (24H2) from the official Microsoft website.
  3. Launch Rufus and select your USB drive.
  4. Choose the Windows 11 ISO you downloaded.
  5. Enable the “Extended Windows 11 Installation” option in Rufus, which applies patches to circumvent TPM, Secure Boot, and CPU checks.
  6. Create the bootable USB and use it to install Windows 11, following on-screen instructions.

Method 2: Registry Edits via Installation Media

For users comfortable with registry edits, modifying the Windows Registry on installation media to bypass checks is an option:

  1. Create Windows 11 Installation Media and boot from it.
  2. Press Shift + F10 at the setup screen to open Command Prompt.
  3. Type regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
  4. Create a new key named LabConfig, and within it, create DWORD values BypassTPMCheck and BypassSecureBootCheck, setting both to 1.

Method 3: Modifying or removing AppraiserRes.dll

Modifying the AppraiserRes.dll file is a technique used by some users to bypass the hardware compatibility check during the Windows 11 installation process. This method specifically targets the component of the Windows setup that verifies if the hardware meets the minimum requirements for Windows 11, such as the TPM 2.0, Secure Boot, and supported CPU. Here’s a detailed, hypothetical guide on how this could theoretically be approached, bearing in mind the risks and ethical considerations of modifying system files.

Disclaimer: It’s important to note that modifying system files and circumventing installation requirements:

  • May violate Microsoft’s Terms of Service.
  • Could potentially expose your system to security vulnerabilities or instability.
  • Might affect your eligibility for future updates and support from Microsoft.
  • Proceed with caution and understand the potential impacts on your system.

Preliminary Steps

  • Backup Your Data: Ensure all important data on the system is backed up to avoid any loss during the process.
  • Download the Windows 11 ISO: Obtain the official Windows 11 ISO from Microsoft’s website.
  • Create a Bootable USB Drive: Use tools like Rufus to create a bootable USB drive from the Windows 11 ISO file.

Finding and Modifying AppraiserRes.dll

Mount the ISO or USB Drive: If you’re working directly on a PC, mount the Windows 11 ISO file by right-clicking it and selecting Mount. If you’re using a bootable USB drive, ensure it’s inserted and accessible.
Navigate to the Sources Folder: Open the mounted ISO or USB drive in File Explorer and navigate to the Sources folder.
Locate AppraiserRes.dll: Within the Sources folder, find the AppraiserRes.dll file. This is the file responsible for conducting the system compatibility check.


Rename the Original File: It’s a good practice to rename the original AppraiserRes.dll file rather than deleting it. For instance, you could rename it to AppraiserRes_old.dll. This way, you have a backup in case you need to restore the original state.
Obtain a Modified AppraiserRes.dll: This step involves finding a modified version of the AppraiserRes.dll file that bypasses the compatibility checks, or modifying the file yourself. Modifying DLL files requires specific tools and knowledge in software development, particularly in reverse engineering. You can download the modified file from here.
Replace the DLL File: Place the modified AppraiserRes.dll file into the Sources folder on your mounted ISO or USB drive, ensuring it has the same name (AppraiserRes.dll) as the original file you renamed.

Method 4: Using GitHub Scripts

Scripts like Skip_TPM_Check_on_Dynamic_Update.cmd available on GitHub automate the process of applying workarounds:

  1. Download the script from a reputable source on GitHub.
  2. Run the script as administrator before starting the Windows 11 installation or upgrade process. This script modifies system settings to ignore TPM checks.
  3. Proceed with the installation or upgrade as usual.

Final Considerations

  • Legal and Ethical Considerations: Ensure compliance with Microsoft’s terms of service and consider the ethical implications of bypassing software restrictions.
  • Long-term Support: Be prepared for the possibility that future updates may not be applicable or may affect the functionality of installations on unsupported hardware.
  • Security: Regularly update your software and maintain strong security practices, especially if bypassing TPM requirements.

In conclusion, while installing Windows 11 on unsupported hardware is technically possible through various methods, it’s a path fraught with potential pitfalls regarding system stability, security, and future support. Users should weigh these factors carefully against the desire to run the latest operating system on older hardware.
