Sets: Sets is designed to make sure that everything related to your task: relevant webpages, research documents, necessary files, and applications, is connected and available to you in one click. Starting today in RS5 builds, we have turned the Sets experiment back on so any Insider who has opted into Skip Ahead will be able to try out Sets. With Sets, 1st party experiences like Mail, Calendar, OneNote, MSN News, Windows and Microsoft Edge become more integrated to create a seamless experience, so you can get back to what’s important and be productive, recapturing that moment, saving time – we believe that’s the true value of Sets. Additional app integration with Sets is expected over time.
