<h3>Overview/Introduction </h3>
<p>Windows 10 is an important release for Windows display scaling. It implements a unified approach to display scaling across all SKUs and devices aimed at these goals: </p>

Inside WDG - Branches and Rings
<h1>Inside WDG - Branches and Rings</h1>
<p>Today, we’re kicking off a new series of articles we’ll publish regularly to Insider Hub called Inside WDG. WDG is short for the Windows and Devices Group which is the group at Microsoft responsible for Windows as well as Microsoft’s devices such as Surface, Xbox, Lumia, and Band. And with Inside WDG, we want to give Insiders a behind-the-scenes look at how we’re building Windows. It will also give us the opportunity go into greater detail on specific topics that we know are of interest to Insiders. For our first Inside WDG article, we’re going to talk about our Windows branches and rings.</p>
<p>Throughout Windows 10 development and over the past year of the Windows Insider Program, we have evolved how we develop and release Windows. We have learned a lot from our Windows Insiders and customers and have made significant improvements to our product and the tools we use to develop them. Therefore, we would like to take the time to give Windows Insiders some backgrou

Inside WDG - Localization Process
<p>Hello Windows Insiders!</p>
<p>My name is Miki Albertson and I’m a Program Manager from Windows Localization team. Today I would like to give you a behind-the-scenes look at how WDG products are made available to Windows Insiders in their language. By the way, we call this process “Localization”.</p>
<p>If you have ever wondered about how our products are made available in your markets and in your language, please read on!"</p>
<p>This is a simplified view, but it will give you an overview into main aspects of Localization process.</p>
<p>Each process is explained in detail below. </p>

Made by You - Cortana listens to your feedback!
<h3>Introduction </h3>
<p>Cortana is really smart, but she isn’t perfect. Cortana does automatically get better, so just using Cortana is a great way to help. In fact, the more you use Cortana the better she gets for everybody. But your feedback is absolutely critical. Feedback helps us identify issues and focus attention to the most urgent needs.</p>
<p>In this article, we’ll show you how to give feedback about Cortana, what we do every day with that critical feedback, and provide real examples where feedback has impacted changes to Cortana.</p>
<h3>Cortana Feedback (How it works and what we do with it) </h3>
<p>One of the key sources of feedback comes from within the Cortana experience. You can provide ideas, likes and dislikes to our team. Each report is recorded by our system, including a screenshot (if you allow), as well as few key details such as the Windows language used. </p>
