Windows 10 Build 10125 packs several new features that make appearance for the first time, such as ability to customize the Start Menu via Settings app, refined date and time pane, new icons, new Windows Hello biometric authentication method, fixed full screen bug and updated settings page in Edge, “back” to previous app button on tablet mode, and etc.
Sometimes, you would wonder why Microsoft likes to hold back on new features from access by Windows Insiders, as by the time Microsoft released build 10122, the build 10125 should have been compiled and could be released instead. Of course, now Microsoft should be several builds ahead.
