Windows 10 build 9879 技术预览版现已提供下载，这个新版本到底有何改进，和上一代版本9860又有何不同，一起来看看吧！

　　在 Win10 9879 中除了视觉外观变化之外，还有涉及到一些系统核心的改变，完整的更新列表在文末给出。 这里不得不提的是，在这个 9879 版本中，已允许用户在任务栏中禁用搜索和任务视图，相信这是大部分人所期望的。

　　除此之外，最明显的变化是通知中心的重新布局。现在它已经被放置在任务栏时钟的旁边，更易于访问，这是微软所希望提供的。

Windows 10 9879

触摸和文件格式的改进

　　更新日志显示，Windows 10 9879 同时也带了一个新的电池指示器，当然它只能在笔记本和平板电脑中显现。Windows 窗口动画也变得更加精致，它提供了相当不寻常的打开和最小化应用程序时的视觉效果，这个在 9860 中看起来似乎未完成的效果。

　　同时，在此版本中，微软还介绍了对MKV文件格式的完整支持，所以你现在可以使用 Windows Media Player 直接打开这种流行格式的影音文件。其实这个功能在之前的版本中已经提供了，但使用过程中发现支持得不是很好，所以微软说了在这次的更新中，已经变理更加稳定。

程序更新

　　微软还发布了一个关于安装程序的大的改进包，例如，现在有选项可以将系统设置备份到 OneDrive ，并可以直接从主菜单上访问存储。zPC设置屏幕，它提供了一些未完成的配置选项，包括更新面板。更重要的是，现在这个特定的应用程序允许您更改桌面墙纸，还有一些额外的自定义选项。

　　最后，Build 9879 是今年最后的更新了。微软说了，新版本里的更新足以让你坚持使用到明年年初，直到新的更新计划推出。隐藏的全部更新如下（来自微软官方）：
