Install Windows Admin Center on Windows Server 2025 [Guide]

Windows Admin Center (WAC) is a free, browser-based management tool from Microsoft that lets you manage Windows Servers, clusters, and Windows 10/11 PCs from a single web interface. It replaces older tools like Server Manager and MMC snap-ins with a modern dashboard that runs in your browser – no agent installation needed on managed servers.

This guide walks through installing Windows Admin Center on Windows Server 2025 or 2022, then covers the key management tasks you can perform from the web console – adding servers, managing Hyper-V VMs, storage, networking, updates, and performance monitoring.

Prerequisites

Before starting the installation, confirm the following requirements are met:

Windows Server 2025 or Windows Server 2022 (Desktop Experience or Server Core)
Local administrator access on the server
At least 2 GB RAM and 2 CPU cores (dedicated or shared)
Microsoft Edge, Google Chrome, or Mozilla Firefox browser
Port 443 (HTTPS) open in Windows Firewall – WAC uses this by default
WinRM (ports 5985/5986) enabled on remote servers you plan to manage
Internet access for downloading the installer (optional for offline installs)

Step 1: Download Windows Admin Center

Download the latest Windows Admin Center installer from the Microsoft Evaluation Center. As of this writing, the latest GA release is version 2511.

On your Windows Server, open PowerShell as Administrator and download the installer directly:

$parameters = @{
    Source = "https://aka.ms/WACdownload"
    Destination = "$env:USERPROFILE\Downloads\WindowsAdminCenter.exe"
}
Start-BitsTransfer @parameters

This downloads the installer to your Downloads folder. The file is approximately 200 MB. If you prefer, you can also download it manually from a browser on any machine and copy it to the server via RDP or a shared folder.

Step 2: Install Windows Admin Center on Windows Server

You can install Windows Admin Center using either the GUI installer or PowerShell. Both methods are covered below.

Method 1: GUI Installation (Desktop Experience)

Double-click the downloaded WindowsAdminCenter.exe file to launch the setup wizard. Walk through these steps:

Welcome screen – Click Next to begin
License Terms – Accept the license agreement and click Next
Installation Mode – Choose Express setup for default settings (recommended) or Custom setup to configure port, TLS certificate, and network access manually. Click Next
TLS Certificate – Select Generate a self-signed certificate for testing, or choose an existing certificate from the local machine store for production. Click Next
Automatic Updates – Leave the default to install updates automatically. Click Next
Diagnostic Data – Choose your preferred telemetry level. Click Next
Ready to Install – Review the summary and click Install
Finish – Check Start Windows Admin Center and click Finish

The installer creates a Windows service called WindowsAdminCenter that starts automatically on boot. Express setup on Windows Server uses port 443 by default.

Method 2: PowerShell Installation (Server Core or Headless)

For Server Core installations or automated deployments, install Windows Admin Center silently from PowerShell. Open an elevated PowerShell session and run:

Start-Process -FilePath "$env:USERPROFILE\Downloads\WindowsAdminCenter.exe" -ArgumentList '/VERYSILENT' -Wait

The /VERYSILENT flag runs the installer with no user interaction. It uses default settings – port 443, self-signed TLS certificate, and automatic updates enabled.

After installation completes, verify the service is running:

Get-Service -Name WindowsAdminCenter

The output should show the service in Running state:

Status   Name                    DisplayName
------   ----                    -----------
Running  WindowsAdminCenter      Windows Admin Center

If the service is not running, start it manually:

Start-Service -Name WindowsAdminCenter

To confirm the port WAC is listening on, run:

netstat -an | Select-String ":443"

You should see port 443 in LISTENING state, confirming WAC is ready to accept connections.

Step 3: Access the Windows Admin Center Web Interface

Open a supported browser (Edge, Chrome, or Firefox) and navigate to the WAC URL. If you installed WAC on the local server, use:

https://localhost

To access WAC from another machine on the network, use the server’s hostname or IP address:

https://server-name-or-ip

If you used a self-signed certificate, the browser will show a certificate warning. Accept the warning to proceed. For production environments, use a certificate from your internal CA or a trusted certificate authority to avoid this.

Sign in with your Windows administrator credentials. The WAC dashboard loads showing the All Connections page where you manage your server fleet.

Step 4: Add Servers to Manage

The local server where WAC is installed appears automatically in the connections list. To add remote servers:

Click Add on the All Connections page
Select Servers as the resource type
Enter the server name or IP address in the text field
Click Add to save the connection

WAC uses WinRM to communicate with remote servers. If the target server is not in the same Active Directory domain, you may need to provide explicit credentials. Click Use another account for this connection and enter domain\username and password for the remote server.

For bulk imports, click Add and select Import servers to upload a text file with one server name per line. This is useful when adding dozens of servers at once.

Once a server is added, click on it to open the server management dashboard. From there you get an overview of CPU, memory, disk, and network usage along with quick access to all management tools.

Step 5: Manage Hyper-V Virtual Machines

If the managed server has the Hyper-V role installed, the Virtual Machines tool appears in the left navigation panel. Click on it to see all VMs on that host.

From the Virtual Machines view you can:

Create new VMs – Click New, set a name, generation (Gen 1 or Gen 2), memory, virtual switch, and virtual hard disk. Attach an ISO for OS installation
Start, stop, and restart VMs – Select a VM and use the toolbar buttons
Connect to VM console – Click Connect to open an in-browser remote console session (Enhanced Session or basic mode)
Create and manage checkpoints – Take snapshots before making changes and revert if needed
Move VMs – Live migrate VMs between Hyper-V hosts in a cluster
Adjust VM settings – Change CPU count, memory allocation, add or remove virtual disks and network adapters

The VM inventory shows each machine’s state, CPU usage, memory demand, and uptime at a glance. This is far more convenient than opening Hyper-V Manager over RDP for every host.

Step 6: Manage Storage and Disks

The Storage section in WAC provides tools for managing local disks, volumes, and file shares without using Disk Management or Server Manager.

Click Disks in the left panel to see all physical disks attached to the server. For each disk you can:

Initialize new disks (GPT or MBR)
Create, extend, shrink, and delete volumes
Format volumes with NTFS or ReFS
View SMART health status and disk properties

Click Files & file sharing to manage SMB shares. You can create new file shares, set share permissions, and browse file system contents directly from the browser. This replaces the need to open Computer Management and navigate to Shared Folders.

For servers running Storage Spaces Direct in a cluster, WAC provides a dedicated Volumes view with pool management, tier configuration, and capacity monitoring.

Step 7: Configure Networking

The Networks tool gives you a unified view of all network adapters, IP configurations, and firewall rules on the managed server.

Click Networks in the left panel to see:

Network adapters – View all physical and virtual NICs with link speed, MAC address, and connection status
IP configuration – View and modify IP addresses, subnet masks, default gateways, and DNS servers for each adapter
NIC teaming – Create and manage NIC teams for redundancy and bandwidth aggregation

Click Firewall to manage Windows Defender Firewall rules. You can view all inbound and outbound rules, enable or disable specific rules, and create new rules – all without touching netsh or the Windows Firewall MMC snap-in.

If you manage servers running DNS or DHCP roles, those tools also appear in the navigation panel when connected to the respective server.

Step 8: Monitor Server Performance

WAC includes built-in performance monitoring that replaces the need for Performance Monitor (perfmon) in most day-to-day scenarios.

Click on a connected server to open its dashboard. The Overview page shows real-time metrics for:

CPU utilization – Current and historical usage graphs
Memory consumption – Total, used, and available RAM
Disk I/O – Read/write throughput and latency per volume
Network throughput – Bytes sent and received per adapter

For deeper analysis, click Processes to see running processes sorted by CPU or memory usage – similar to Task Manager but accessible remotely. You can end unresponsive processes directly from the interface.

The Events tool provides access to the Windows Event Viewer logs. Filter by log name, source, level (Error, Warning, Information), and time range to quickly find relevant events without opening a full Event Viewer session.

Step 9: Manage Windows Updates

The Updates tool in WAC lets you check for, download, and install Windows updates on managed servers without using WSUS or connecting to each server individually.

Click Updates in the left panel. WAC checks for available updates and displays them in a list with KB numbers, severity, and description. From here you can:

Check for updates – Scan for the latest available patches
Install selected updates – Choose specific updates and install them
Install all updates – Apply all available patches at once
View update history – See previously installed updates and their status
Schedule restarts – Set a maintenance window for the required reboot

For environments using WSUS, WAC integrates with your existing update infrastructure and shows only approved updates. For standalone servers pulling from Microsoft Update directly, WAC handles the entire process.

Step 10: Install Extensions

Windows Admin Center supports extensions that add management capabilities beyond the built-in tools. Extensions are available from the WAC extension feed maintained by Microsoft and third-party vendors.

To install extensions:

Click the Settings gear icon in the top-right corner of WAC
Select Extensions from the left menu
Browse the Available extensions tab to see what is available
Click Install on any extension you want to add

Some commonly used extensions include:

Active Directory – Manage AD users, groups, and computers
DNS – Manage DNS zones and records on Windows DNS servers
DHCP – Manage DHCP scopes, leases, and reservations
GPU management – Monitor GPU utilization on servers with discrete GPUs
Containers – Manage Windows containers on the server

Extensions install directly into the WAC gateway and become available immediately. They update independently from the main WAC installation. Check the Available extensions tab periodically for new tools and updates.

Conclusion

Windows Admin Center gives you a single browser-based console for managing Windows Server 2025 and 2022 infrastructure – from IIS web servers to Hyper-V hosts to file servers. The installation takes under five minutes and the web interface is accessible from any modern browser on the network.

For production deployments, replace the self-signed certificate with one from your internal CA, restrict network access to management VLANs, and consider deploying WAC in high-availability mode with a failover cluster for critical environments.
