Need advice to install Windows 11 25H2 on unsupported PC

You can still install Windows 11 25H2 using an in-place upgrade method even the PC doesn't meet Windows 11 official hardware requirements (like TPM 2.0 or Secure Boot). This approach is ideal for users who prefer a graphical setup process, want to keep their files, apps, and settings, and don't want to boot from USB drives or mess with third-party tools. By replacing a single system file in the ISO, you can easily bypass hardware checks and install windows 11 25H2 on any unsupported PC.

Step 1. Make sure your PC is running Windows 10 (version 2004 or later) and has at least 15GB of free space on the system drive.

Step 2. Back up your important files, just in case.

Step 3. After the ISO is downloaded, right-click on it and select Mount. A new virtual drive will appear in File Explorer (e.g., D:\), showing the Windows 11 setup files.

Step 4. Navigate to the mounted ISO, then go to the sources folder.

Step 5. Find and delete the file named appraiserres.dll.

Step 6. In the root of the ISO (or the copied folder), double-click setup.exe.

Step 7. The Windows 11 installer will launch. Choose the "Keep personal files and apps."

Step 8. Proceed with the prompts. The upgrade process typically takes 20–60 minutes, depending on your system specs.

Your PC will restart several times. You'll eventually land on the Windows 11 25H2 desktop with your files and apps intact. This is one of the best ways to upgrade to Windows 11 25H2 on any PC.
