Microsoft has delivered on its promise of 2015 to make OpenSSH available by including it into the recent releases of Windows Server and Windows 10.
That said, the OpenSSH is being introduced as a “feature-on-demand” in the recent release of Windows Server 2019 and Windows 10 1809.
“OpenSSH,” a set of utilities allows client and servers to connect securely into Windows.
Users, when connected, can remotely log in, do file transfer, and manage a public/private key pair.
The tool has been around for a while and it was originated as part of the OpenBSD project. BSD, Linux, macOS, and Unix ecosystems have been using it for many years.
Microsoft builds a Win32 port of OpenSSH and added it as a “pre-release” feature first into the Windows 10 Fall Creators Update as well as in Windows Server 1709.
It was then included as supported feature on-demand in Windows 10 1803. However, Windows Server hadn’t received the feature until now.
But that’s changed now as Microsoft has bundled OpenSSH as a supported feature in Windows Server 2019 again.
By adding OpenSSH into Windows Server 2019, admins will be able to remote manage server administration across a range of operating systems.
What is the state of OpenSSH and PowerShell?PowerShell Remoting over SSH is supported with PowerShell Core. While PowerShell Core is dependent on OpenSSH for PowerShell remoting over SSH, OpenSSH is an independent project.
Here are the top five features in the current release of Windows Server 2019:
Windows Admin Center
Microsoft has made a preview of Windows Admin Center ( WAC) available to Insiders.
WAC is designed to modernize and simplify IT administration experience with remote server management as it surfaces all-new Server 2019 features.
The browser-based super lightweight tool is projected as a replacement for “In Box” admin tools including Server Manager, DHCP manager, Hyper-V manager, and 20 MMC consoles.
Being browser based it support latest versions of Microsoft Edge and Google Chrome.
Though it works out of the box in Server 2019, following Server versions need extra steps to begin managing with Windows Admin Center:
- Windows Server 2012 and 2012 R2
- Windows Server 2008 R2
- Microsoft Hyper-V Server 2016
- Microsoft Hyper-V Server 2012 R2Watch this how to get started with WAC video:
Hyper-Converged Infrastructure (HCI) and Windows Server Software-Defined Datacenter (WSSD)
HCI and WSSD consolidates software-defined compute, storage, and networking into a single cluster and offer high-performance, cost-effective, and scalable virtualization.
A new predictive analytics feature locally analyzes Windows Server system data such as performance counters and servers events using machine-learning (ML) model.
Here is an overview of how to get started with System Insights:
Linux on Windows Server 2019
Windows Subsystem for Linux on Windows Server 2019 allows of running GNU/Linux environment like most command-line tools, utilities, and applications.

Storage Migration Services
The SMS offer easier ways to move to a newer version of Windows Server.
This graphical tool inventories servers data transfer data and configuration from older server to the new server without having to change anything.
By using Storage Migration Service, admins can complete following tasks:
- Inventory multiple servers and their data
- Rapidly transfer files, file shares, and security configuration from the source servers
- Optionally take over the identity of the source servers (also known as cutting over) so that users and apps don’t have to change anything to access existing data
- Manage one or multiple migrations from the Windows Admin Center user interface
Check out more about Storage Migration Services in the documentation here.

There are several notable new features for hyper-converged infrastructure:
Multi-select bulk actions for drives, volumes, and servers
With full support for shift/ctrl + click keyboard shortcuts, confirmation dialogs, and improved notifications. For example, you can now delete multiple volumes with just one click:
Monitor storage per-server
How much storage capacity is used per server, and how much needs to repair (normal after restarting), is now visible on the Server detail. Now you can track exactly how resync is progressing without relying on Get-StorageJob!
Better network activity monitoring
The Server detail page now has separate charts for non-RDMA and RDMA networking, each showing inbound and outbound traffic separately (summed over all adapters in the server).
