The Windows 10 Insider Preview current build comes with a feature called Insider Hub that gives you the insider's access to what the Windows 10 team is up to. The app profiles a list of features and announcements and kees you up-to-date with the Windows 10 progress and updates and provides feedback.
Insiders also get to connect with the Windows team, share ideas and even get a chance to go to Microsoft Office. See the announcement below.
