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. This build also include all lock screen wallpapers from the RTM.
