What Is Windows 11 Validation OS
Microsoft Validation OS is a minimal, fast, and customizable Windows 11-based operating system. It is used by Windows device manufacturers as an aid during early design stages. It is capable of diagnosing, mitigating, and repairing hardware defects during the Windows device manufacturing process.
Like Windows Preinstallation Environment, Windows 11 Validation OS runs from a RAM disk and boots into a Command Prompt. This lightweight operating system is not suitable for ordinary users. Instead, it is built for hardware or software vendors, developers, or technicians. It is not limited to built-in tools. It supports Win32 apps.
Microsoft quietly updated Windows 11 Validation OS with a new ISO. The ISO holds lots of updates, including support for the latest Windows 11 features and updates, updated drivers for a variety of hardware devices, as well as new tools and utilities for troubleshooting and debugging.
