Microsoft quietly updates Validation OS based on Win11 22H2, ISO image file is 340 MB

Developers have discovered that Microsoft has quietly updated the Validation OS based on the 22621.1702 version without any announcement. The ISO image file is only 340 MB in size.

The Validation OS is a pre-release version of Windows that is used by Microsoft to test new features and bug fixes before they are released to the public. It is not intended for general use, but it can be downloaded by developers and enthusiasts who want to try out the latest Windows features.

The latest update to the Validation OS includes a number of new features and bug fixes, including:

• Support for the new Start menu design in Windows 11 22H2

• Improvements to the Taskbar and Action Center

• New features for the Microsoft Store

• Bug fixes for a number of known issues

The ISO image file for the updated Validation OS can be downloaded from the Microsoft website. To install the Validation OS, you will need to create a bootable USB drive or DVD. Once you have created the bootable media, you can boot your computer from it and start the installation process.

The Validation OS is not a stable release of Windows, so it is important to use it at your own risk. There may be bugs and other issues that could affect your computer. If you are not comfortable using an unstable operating system, you should wait for the official release of Windows 11 22H2.
