This morning, Microsoft is pushing a new preview version of Windows 11 for Insider members of the Dev channel, with the operating system version number Build 22523. Due to time constraints and the Microsoft team celebrating Christmas, 22523 will be the last major version of Windows 11 this year. For this reason, the official ISO image is also open for download.
At present, apart from the latest Windows 11 22523, the ISO images available for Insider members to download in the Windows Download Center also include the official version Build 22000.194 and Windows 10 21H2 (November Update) Build 19044.1288.
Installation Method:
After downloading the ISO image to the local hard disk, double-click to mount it automatically. After mounting, you can continue to find Setup.exe and double-click. If you choose to keep the settings and files, it is a non-destructive upgrade. If you don’t keep it, it means a clean installation.
Of course, for ease of use, you can also create a bootable USB flash drive with the help of Rufus, etc. Microsoft also gave a detailed tutorial.
