Windows 11 22H2 (2022 Update) has been available since September 20, 2022, and the best way to upgrade is to perform a clean installation using a USB flash drive.

Although Microsoft always recommends using an in-place upgrade through Windows Update, modifying the current installation can cause problems and unexpected errors due to compatibility issues and custom system configurations you may have applied. When you use a clean install of Windows 11 22H2, the chances of problems will be minimal because you will be deleting everything and applying a fresh copy of the operating system.

Also, if you have had the same setup for many months, erasing everything and starting from scratch can help resolve existing problems and improve startup times, performance, and memory usage.

While there are multiple ways to proceed with a clean installation, the best approach is to use a USB bootable media with the Windows 11 22H2 files, which you can create using the Media Creation Tool, the official ISO file, or third-party tools like Rufus.

In this guide, you will learn the steps to a fresh installation of the Windows 11 2022 Update using a bootable USB flash drive whether you currently have a device with Windows 11 21H2, Windows 10, or an older version. 

Important: This process will delete everything on your device. It’s recommended to make a full backup of your computer before proceeding. You’ve been warned.
