The content in this section describes what's new and changed in Windows Server® 2016. The new features and changes listed here are the ones most likely to have the greatest impact as you work with this release.
Compute
The Virtualization area includes virtualization products and features for the IT professional to design, deploy, and maintain Windows Server.
General
Physical and virtual machines benefit from greater time accuracy due to improvements in the Win32 Time and Hyper-V Time Synchronization Services. Windows Server can now host services that are compliant with upcoming regulations which require a 1ms accuracy with regards to UTC. 1
Hyper-V
What's new in Hyper-V on Windows Server 2016. This topic explains the new and changed functionality of the Hyper-V role in Windows Server 2016, Client Hyper-V running on Windows 10, and Microsoft Hyper-V Server 2016.
Windows Containers: Windows Server 2016 container support adds performance improvements, simplified network management, and support for Windows containers on Windows 10. For some additional information on containers, see Containers: Docker, Windows and Trends.
Nano Server
What's New in Nano Server. Nano Server now has an updated module for building Nano Server images, including more separation of physical host and guest virtual machine functionality as well as support for different Windows Server editions.
There are also improvements to the Recovery Console, including separation of inbound and outbound firewall rules as well as the ability to repair the configuration of WinRM.
Shielded Virtual Machines
Windows Server 2016 provides a new Hyper-V-based Shielded Virtual Machine to protect any Generation 2 virtual machine from a compromised fabric. Among the features introduced in Windows Server 2016 are the following:
New "Encryption Supported" mode that offers more protections than for an ordinary virtual machine, but less than "Shielded" mode, while still supporting vTPM, disk encryption, Live Migration traffic encryption, and other features, including direct fabric administration conveniences such as virtual machine console connections and Powershell Direct.
Full support for converting existing non-shielded Generation 2 virtual machines to shielded virtual machines, including automated disk encryption.
Hyper-V Virtual Machine Manager can now view the fabrics upon which a shielded virtual is authorized to run, providing a way for the fabric administrator to open a shielded virtual machine's key protector (KP) and view the fabrics it is permitted to run on.
You can switch Attestation modes on a running Host Guardian Service. Now you can switch on the fly between the less secure but simpler Active Directory-based attestation and TPM-based attestation.
End-to-end diagnostics tooling based on Windows PowerShell that is able to detect misconfigurations or errors in both guarded Hyper-V hosts and the Host Guardian Service.
A recovery environment that offers a means to securely troubleshoot and repair shielded virtual machines within the fabric in which they normally run while offering the same level of protection as the shielded virtual machine itself.
Host Guardian Service support for existing safe Active Directory – you can direct the Host Guardian Service to use an existing Active Directory forest as its Active Directory instead of creating its own Active Directory instance
For more details and instructions for working with shielded virtual machines, see Shielded VMs and Guarded Fabric Validation Guide for Windows Server 2016 (TPM).
Identity and Access
New features in Identity improve the ability for organizations to secure Active Directory environments and help them migrate to cloud-only deployments and hybrid deployments, where some applications and services are hosted in the cloud and others are hosted on premises.
Active Directory Certificate Services
Active Directory Certificate Services (AD CS) in Windows Server 2016 increases support for TPM key attestation: You can now use Smart Card KSP for key attestation, and devices that are not joined to the domain can now use NDES enrollment to get certificates that can be attested for keys being in a TPM.
Active Directory Domain Services
Active Directory Domain Services includes improvements to help organizations secure Active Directory environments and provide better identity management experiences for both corporate and personal devices. For more information, see What's new in Active Directory Domain Services (AD DS) in Windows Server 2016.
Active Directory Federation Services
What's New in Active Directory Federation Services. Active Directory Federation Services (AD FS) in Windows Server 2016 includes new features that enable you to configure AD FS to authenticate users stored in Lightweight Directory Access Protocol (LDAP) directories. For more information, see What's New in AD FS for Windows Server 2016.
Web Application Proxy
The latest version of Web Application Proxy focuses on new features that enable publishing and preauthentication for more applications and improved user experience. Check out the full list of new features that includes preauthentication for rich client apps such as Exchange ActiveSync and wildcard domains for easier publishing of SharePoint apps. For more information, see Web Application Proxy in Windows Server 2016.
Administration
The Management and Automation area focuses on tool and reference information for IT pros who want to run and manage Windows Server 2016, including Windows
PowerShell.
Windows PowerShell 5.1 includes significant new features, including support for developing with classes and new security features that extend its use, improve its usability, and allow you to control and manage Windows-based environments more easily and comprehensively. See New Scenarios and Features in WMF 5.1 for details.
Cloud Witness
Cloud Witness is a new type of Failover Cluster quorum witness in Windows Server 2016 that leverages Microsoft Azure as the arbitration point. The Cloud Witness, like any other quorum witness, gets a vote and can participate in the quorum calculations. You can configure cloud witness as a quorum witness using the Configure a Cluster Quorum Wizard.
For more info, see Deploy Cloud Witness.
Health Service
The Health Service improves the day-to-day monitoring, operations, and maintenance experience of cluster resources on a Storage Spaces Direct cluster.
