If your PC doesn't meet Windows 11official requirements (like TPM 2.0, Secure Boot, or a supported CPU), you can still perform a clean install using a modified ISO. By following the steps in below, you will learn how to upgrade to Windows 11 for free.

2. Insert a USB (8GB for more) to Windows 10 PC.

3. Open the WiinBootMate app and select the USB.

4. Import the Windows 11 ISO. Under Image Options, choose the "Bypass Windows 11 System Check" option.
