WGA consists of two components: an installable component called WGA Notifications that hooks into Winlogon and validates the Windows license upon each logon and an Active X control that checks the validity of the Windows license when downloading certain updates from the Microsoft Download Center or Windows Update.WGA Notifications covers Windows XP and later, with the exception of Windows Server 2003 and Windows XP Professional x64 Edition.You can customize Windows Recovery Environment (Windows RE) by adding languages, packages drivers, and custom diagnostic or troubleshooting tools.The Win RE image is included inside the Windows 10 and Windows Server 2016 images, and is eventually copied to the Windows RE tools partition on the destination PC or device.While HTML5 form validation is typically about missing or invalid text inputs, there are other form element types that also require attention. Suppose you have a form on your website that at the bottom asks people to "accept the Terms and Conditions" or something similar.Basically you don't want the form to be submitted unless this is checked.Included in the Windows Assessment and Deployment Kit (Windows ADK), Windows Performance Recorder (WPR) is a performance recording tool that is based on Event Tracing for Windows (ETW).
Note To ensure a consistent language experience in recovery scenarios, add the same set of languages to the Windows RE image that you add to the Windows image.
We recommend that when you update your Windows images with languages and boot-critical drivers, update the Windows RE image at the same time.
This topic also gives optional steps to optimize the Windows RE image after updating it.
You can download WPR by visiting Windows Insider Program.
