• If your computer doesn't meet the requirements (like missing TPM), don't worry. Just click Next to skip those checks.

  

• Pick your language and region, then click “Start Upgrading”. When asked, click “Sure” to confirm.

  

• Wait while the tool bypasses the system checks. After that, your PC will be ready to install Windows 11!
