Windows 10 build 10159

Windows 10 build 10159 is a build of Windows 10. This build was released to Windows Insiders in the Fast Ring on 30 June 2015, only a day after its predecessor, build 10158. It was released so early because of an "interesting change", that being the new default Hero wallpaper. A redesigned version of the login screen is also included. Apart from the aforementioned cosmetic changes, this build also contains over 300 bug fixes.
