Microsoft pushes Win10 preview again, the login interface changes greatly

Lei Feng.com July 1st news, yesterday Microsoft pushed the Win10 10158 preview version to users, and the official version of Win10 was released in less than one month. It is reasonable to say that Microsoft will not make new moves. Unexpectedly, Microsoft has released the Win10 10159 version today.
Although the time difference between the two versions is only one day, according to Microsoft's news, the Win10 10159 version has more than 300 bug fixes and brings a new Windows 10 Hero ("hero") wallpaper.
It is reported that in addition to the hero wallpaper, the login interface has also changed. The new Win10 landing page can be based on the user's desktop wallpaper, and the user's avatar is adjusted to the center of the screen. The other aspects are basically the same as the previous version.
Summary, it can be seen that compared to the Win10 10158 preview version of the comprehensive upgrade, the 10159 version has not made a big improvement in the function, the new version is also mainly optimized in the user experience. So the question is coming, will this be the last preview version?
