Windows Admin Center

Windows Admin Center, first released in 2018, is a browser-based management platform and solution, providing tools for the management, configuration, troubleshooting and maintenance of Windows operating systems. Preview Version 2 of an Azure-native deployment of Windows Admin Center has been available since March 2021, offering consumers of Azure Windows VMs the opportunity to use these same tools directly from the Azure Portal. Where these features really shine is in the management of Windows Server Core, a GUI-less Windows Server deployment.


Windows Server Core - A Quick Introduction

Windows Server Core is a lightweight installation option for Windows Server that eliminates services and other features not required for commonly used server roles. The smaller code base presents a much smaller attack surface compared to the typical Windows Server install, making it perfect for server roles that don't require a graphical user interface (GUI) or are already intended to be managed remotely (e.g. Hyper-V). However, the lack of a GUI can present a challenge for users that are less comfortable managing and configuring Windows Server using the command line or Powershell.


Windows Admin Center

Windows Admin Center (WAC) provides some of those GUI elements directly via the Azure Portal, enabling the user to manage and configure their Server Core instance without the need for command line or Powershell knowledge. From the overview, you're presented with some key server information (hostname, Windows edition, domain etc.) as well as utilisation statistics.

From the menu on the left hand side you're able to navigate through the different functions of the Admin Center - anyone who has used the locally-installed version of WAC will feel at home, as functionally and visually it is very similar to the on-premises version.

For example, you're able to view the Processes currently running on the server and perform the same actions you'd expect to be able to carry out through the GUI Task Manager, such as starting and ending processes; you're also able to view resource metrics and related Services by selecting a specific process and navigating the tabbed panel at the bottom of the window.

Similarly, the Events function provides much the same functionality as the Event Viewer in Windows with the ability to filter based on event ID as well as view event details and descriptions.

For activities and workflows that aren't supported in WAC, you're able to run Powershell natively from the Azure Portal using the Powershell function directly on the machine.


Windows Admin Center adds powerful OS-level management tools for Windows VMs available directly from the Azure Portal, at no additional cost. Used in conjunction with Windows Server Core, it's possible to realise the advantages of the reduced attack surface without losing access to GUI tools that are used daily in the management and configuration of the Windows OS and installed applications.
