HowTo Install Windows Admin Center…on Windows 2022 Core Edition

Hello World, 

In our previous post, we have quickly provided a quick overview of the Windows Admin Center (WAC) software solution provided by Microsoft.  Windows Admin Center is a web based administration tool that allows sysadmins to perform their day to day jobs when working in a Windows based network.   Microsoft sells this tool as the next iteration of Server Manager and MMC tools since the tool provides a new way of managing the infrastructure 

In this post,  we will provide a quick step by step guide on how to perform a simple installation of the Windows Admin Center… 

Let’s do this ! 


More and more companies are moving into Core Editions because it’s more secure but because it has also a smaller footprint and can be patched more quickly as well.  However, not everyone is comfortable with Core editions where administration is done through Command line.   To overcome this situation,  Windows Admin Center can help traditional windows sysadmins to move forward and accept to have more Windows core editions servers running on their network. 

The move to core edition Server is driven by the current economical situation.  Indeed, Shortage of chips, hardware price increase, availability of hardware components pushes companies to do more with less.  To optimize resources, companies have started strong consolidation of their IT Infrastructure, chasing ghost and unused machines.  Another approach also consists of replacing classical admin Remote Desktop Servers which has can be expansive (RDS CAL Licensing) and deploy Windows Admin Center Server which is free and also require a smaller foot print. 

This post will assume that Windows Admin Center Software will be installed on a Core Edition Server and that Windows Admin Center will be installed in a Gateway configuration mode. This mode will allow a windows admin user to add more servers into the web interface and manage from this central web interface multiple servers available on the network.

Step by Step Installation

The process is exactly identical.

Step 1 – Download the Windows Admin tools 

You will need to obtain the Windows Admin Center software binaries.  You can obtain them by visiting Microsoft web site ( and download the package to your computer and then transfer it to the Windows Core Edition server that will be hosting the Windows Admin Center 

You can also download the package directly from your Windows Core Edition server if it’s connected to the internet.  You will need to go the the Windows PowerShell Console and issue the following command

Invoke-WebRequest -Uri -UserBasicParsing -outfile windowsAdminCenter-xxx.msi

Final Notes 

This is it for this post !  

At this stage, you should have a working installation of Windows Admin Center in Gateway mode.  It’s time for you to see all the options that are available through the web interface and see how you can add additional servers to be managed.   The Tool is really user friendly, not to difficult to use and you can also have access to PowerShell or Remote Desktop, from the browser… WAC can help moving from a traditional way of managing servers (via RDP mainly) into a web interface or even through command line (CLI)

 We might publish some posts about Windows Admin Center to get even more information and configuration tips… but not sure. We need to start working on other topics as well…. 

Till next time 

See ya
