Removed and deprecated features in Windows Server 2019

Windows Server 2019 is the next generation of Microsoft's Windows Server product. It includes various changes made to security, scalability and reliability of the platform.

Almost every Windows user knows that each release of Windows not only adds new features but also removes a number of things Microsoft deprecates. The same happens to Windows Server. Developers occasionally remove features and functionality, providing a replacement solution. Here are the details about the features and functionalities that have been removed in Windows Server 2019.

Features removed in Windows Server 2019

• Business Scanning, also called Distributed Scan Management (DSM). Microsoft are removing this secure scanning and scanner management capability because there are no devices that support this feature.
• Internet Storage Name Service (iSNS). The iSNS protocol is used for interaction between iSNS servers and clients. Server Message Block provides essentially the same functionality, as well as other features.
• Print components in Server Core. In previous releases of Windows Server, the print components were disabled by default in the Server Core installation option. We changed that in Windows Server 2016, enabling them by default. In Windows Server 2019, those print components are once again disabled by default for Server Core. If you need to enable the print components, you can do so by running the Install-WindowsFeature Print-Server cmdlet.
• Remote Desktop Connection Broker and Remote Desktop Virtualization Host in a Server Core installation. Desktop Session Host (RDSH), which requires Server with Desktop Experience; to be consistent with RDSH we're changing these roles to also require Server with Desktop Experience. These RDS roles are no longer available for use in a Server Core installation. If you need to deploy these roles as part of your Remote Desktop infrastructure, you can install them on Windows Server with Desktop Experience. These roles are also included in the Desktop Experience installation option of Windows Server 2019.

Deprecated features

• Key Storage Drive in Hyper-V. Microsoft are no longer working on the Key Storage Drive feature in Hyper-V. If you’re using generation 1 VMs, check out Generation 1 VM Virtualization Security for information about options going forward. If you’re creating new VMs use Generation 2 virtual machines with TPM devices for a more secure solution.
• Trusted Platform Module (TPM) management console. The information previously available in the TPM management console is now available on the Device security page in the Windows Defender Security Center.
• Host Guardian Service Active Directory attestation mode. This feature is now deprecated. Instead, there is a new attestation mode, host key attestation, that's far simpler and equally as compatible as Active Directory based attestation. This new mode provides equivalent functionality with a setup experience, simpler management and fewer infrastructure dependencies than the Active Directory attestation. Host key attestation has no additional hardware requirements beyond what Active Directory attestation required, so all existing systems will remain compatible with the new mode.
• OneSync service. The OneSync service synchronizes data for the Mail, Calendar, and People apps. A sync engine that has been added to the Outlook app provides the same synchronization.
• Remote Differential Compression API support. Remote Differential Compression API support enabled synchronizing data with a remote source using compression technologies, which minimized the amount of data sent across the network. This support isn’t currently used by any Microsoft product.
• WFP lightweight filter switch extension. The WFP lightweight filter switch extension enables developers to build simple network packet filtering extensions for the Hyper-V virtual switch. You can achieve the same functionality by creating a full filtering extension. So, Microsoft is about to remove this extension in the future.
