So, the first ever Windows 10 Redstone 2 Build is now live for Insiders in Fast Ring. Microsoft has pushed Windows 10 Build 14901 to Insiders and the first build brings “improved product education” as a change. There are some known issues too and you can read them below.

Build 14901 Changelog:

Improving Product Education: As part of an effort to explore new ways of educating our customers on features in Windows 10 – we are testing out new notifications within File Explorer. They’re designed to help customers by providing quick, easy information about things they can do or new features they can try to have a better experience with Windows 10. If you want to opt out of these notifications, you can do so by unchecking ‘Show sync provider notifications’ from the Options menu in the File Explorer View tab.
