Some of the details of this release are as follows
At the heart of the Microsoft Cloud Platform, Windows Server brings Microsoft’s experience delivering global-scale cloud services into your infrastructure. Windows Server 2016 Technical Preview 4 provides a wide range of new and enhanced features and capabilities spanning server virtualization, storage, software-defined networking, server management and automation, web and application platform, access and information protection, virtual desktop infrastructure, and more.
A highlight of this technical preview is the first public build of Hyper-V Containers, a deployment option for Windows Server Containers. To evaluate either the new Hyper-V Containers or Windows Server Containers, please follow the guidance available on the MSDN Containers site.
As a reminder, these are early pre-release builds. Many of the features and scenarios are still in development. As such, these builds are not intended for production environments, labs, nor full evaluations. This is pre-released software; features and functionality may differ in the final release.
