Windows 11 22H2 (also referred to as the “2022 Update”) is available starting September 20 2022 and if you plan to upgrade your device running Windows 11 21H2 or Windows 10 as soon as it becomes available, you will be able to proceed using the official ISO file, Windows Update and Installation Assistant.
Problem is my PC did not receive this update and I found out 1 method which is using Installation Assistant from here.
It take less than 1 hour to complete the update.
