Windows 10 build 10147

On 2015-06-18, this build leaked onto the Internet. It contains many improvements over build 10130, the latest available public preview build at the time. The desktop UI (the look and feel of the controls, title bars, etcetera for desktop applications) has been updated to better suit the overall cohesion of the UX. This is the first Windows 10 build known to implement many hallmarks of RTM-style activation. When clean installing, you are prompted for a product key  twice . It should also be noted that the key previously used to activate no longer works with this build. However, activation appears to carry over when updating.

This build is the first to include the Microsoft Edge branding in the new web browser. It also includes a new dark theme for Edge. The taskbar expand button icon has been updated.
