Quick Guide on how to install Windows 11 on Unsupported Hardware

Quick Guide on how to install Windows 11 on Unsupported Hardware

Our Tech Team has been testing and using Windows 11 since Microsoft first came out with its preview version (Dev or Insider Program).  Our goal is to learn as much as we can on how to install Windows 11 on our current computer with unsupported hardware, and with minimal or no modification needed.

We have come up with 2 scenarios in which our customer will benefit if they have a guide that they can follow with simple and uncomplicated steps.

  • Clean Install
  • In-Place Upgrade / Repair Install



Downloading the Official Windows 11 Installer and creating the installation media


It is highly recommended to download the official released copy of Windows 11 installer through the Microsoft website.  To download, click the link below.



Creating Windows 11 USB Installation Media 


You can use a number of applications or software to create your Windows 11 USB Installation Media.  It will also require a USB Flash Drive with at least 8GB capacity.  


For a complete guide on how to create Windows Installation Media on a USB Flash Drive, you may visit our website using the link below.



Preparing your Installation Media to Install Windows 11 on unsupported hardware


There have been a couple of tutorial videos in YouTube and Facebook Pages showing how to install Windows 11 on unsupported and older hardware.  Most of the instructions include downloading both Windows 10 and 11 ISOs and copying the install.WIM of Windows 11 and moving it to the Windows 10 ISO.  Others illustrate editing the appraiserres.dll file located in the Sources folder and removing all command lines that include TPM.


However, these processes come with their own limitations based on our tests such as being useful for clean install but not In-Place Upgrade.  


The most effective and efficient way of creating a Windows 11 Installation Media that can bypass CPU Compatibility, TPM, and UEFI SecureBoot And can be used for Clean Install, In-Place Upgrade or In-Place Repair is by completely deleting appraiserres.dll from the /sources folder.


We have prepared a simple guide to help you with the process.   Disclaimer:  We are not liable for any error or unfavorable results.


Step 1

Download the Official Windows 11 Installer ISO through the official Microsoft website only.



Step 2

Create the USB Installation Media with Windows 11 using Windows11 Media Creation tool, RUFUS, or any similar apps.


Refer to our Installation guide for details.



Step 3

Permanently delete (Shift + Del key) the appraiserres.dll file located in the /sources folder.

Step 4

For Clean install, boot your computer via USB and proceed with the installation as normal or run Setup.exe if you are initiating the In-Place Upgrade or Repair process.


Follow the on-screen prompts to finish installing Windows 11.



In the multiple tests we conducted, deleting the appraiserres.dll file required the least effort, and was able to install Windows 11 without the usual requirements such as UEFI SecureBoot and GPT HDD/SSD partitioning.    if you have unsupported hardware, be sure to give this a try.
