Understanding Azure Arc and Its Role on Windows Server 2025
Azure Arc is a powerful tool designed to extend Azure services to on-premises infrastructure, enabling centralized management and operations across hybrid environments. For Windows Server 2025 users, Azure Arc acts as a bridge, allowing you to manage your local servers alongside Azure resources through a unified platform. However, there may come a time when you need to remove Azure Arc from your Windows Server setup.

Whether you're migrating to a different cloud solution, optimizing your on-prem infrastructure, or simply no longer need the features provided by Azure Arc, understanding how to properly disconnect and remove this setup is essential for maintaining a clean and efficient server environment.
Before diving into the steps for removal, it's important to understand what Azure Arc does on your server. By connecting your Windows Server 2025 to Azure Arc, you unlock several benefits, such as:
Unified management: Centralized management of on-premises servers and cloud-based resources.
Azure policy enforcement: Azure Arc allows you to apply Azure policies to your on-prem infrastructure, ensuring consistency across your environment.
Security features: You can integrate Azure security features like Azure Security Center and Azure Sentinel for proactive protection.
Application deployment and monitoring: Azure Arc enables you to deploy, monitor, and manage applications across hybrid environments.
Despite these advantages, there may be reasons to remove Azure Arc, such as transitioning to a more tailored on-prem solution or addressing performance concerns caused by hybrid workloads. Understanding the importance of properly detaching Azure Arc from your server is critical to avoid configuration conflicts and to ensure that all dependencies are removed thoroughly.
In the next section, we’ll explore the exact steps for removing Azure Arc from Windows Server 2025 and what to expect during the process.
Step-by-Step Process to Remove Azure Arc Setup from Windows Server 2025
Removing Azure Arc from Windows Server 2025 isn’t a complicated process, but it does require careful attention to ensure all components are properly unlinked and the server returns to a non-hybrid configuration. Follow these steps to safely remove Azure Arc and its dependencies:
1. Backup Your Server Configuration and Data
Before making any changes to your server configuration, it’s important to create a backup of your server’s settings and any important data. Although the removal of Azure Arc is generally safe, it’s always a good practice to safeguard your information in case anything goes wrong during the process. You can use Windows Server Backup or any other trusted backup tool to ensure your data is secure.
2. Disconnect Azure Arc from the Server
The first step in removing Azure Arc from your Windows Server 2025 is to disconnect the server from the Azure Arc service. This can be done through the Azure portal, where your server is registered. Follow these steps:
Open the Azure portal and navigate to the Azure Arc section.
Locate the Server that is connected to Azure Arc under the "Servers" tab.
Select the server and click Disconnect or Remove from the Azure Arc service. This will effectively unlink the server from Azure management.
Disconnecting the server from Azure Arc will stop it from reporting its status and configuration to Azure, but additional cleanup is required on the server itself.
3. Uninstall the Azure Arc Agent on Windows Server 2025
Azure Arc relies on an agent installed on your Windows Server to communicate with Azure. To fully remove Azure Arc, you’ll need to uninstall this agent. Here's how you can do that:
Open PowerShell with administrative privileges.
Run the following command to check the status of the Azure Arc agent:
Get-Service -Name "AzureConnectedKubernetesCluster" | Select-Object Name, Status
If the agent is running, stop the service using the following command:
Stop-Service -Name "AzureConnectedKubernetesCluster"
Next, uninstall the agent by running this command:
Uninstall-Module -Name Az.HybridCompute
This will remove the Azure Arc agent module from your Windows Server.
To confirm that the agent has been removed, run the following command:
Get-Module -ListAvailable | Where-Object {$_.Name -like "Az.HybridCompute"}
If no results are returned, the agent has been successfully removed from the server.
4. Clear Azure Arc-Related Configuration Settings
Azure Arc may have added several configurations to your server to integrate it into the hybrid cloud model. To ensure a clean removal, you’ll need to remove any Azure-related configurations:
Open PowerShell again with administrative privileges.
Run the following command to remove any Azure-related extensions or configurations:
Remove-AzureRmResourceGroupDeployment -ResourceGroupName
Replace with the appropriate name of the resource group where Azure Arc settings were applied.
Check your server for any Azure Arc-specific configurations, such as custom DNS settings, IP ranges, or firewall rules, and manually remove or revert them as needed.
5. Verify and Revert Server Settings to Original State
Once you have uninstalled the Azure Arc agent and cleared any associated configurations, verify that your server is no longer connected to Azure. You can do this by checking the server’s status in the Azure portal or using PowerShell to ensure that the server is no longer listed as part of Azure Arc.
Additionally, you may need to revert any other changes made to your server during the Azure Arc setup process. This could include adjustments to your networking settings, security policies, or software configurations. Ensure that everything is restored to its previous state, taking into account any custom settings your organization may have had in place before Azure Arc integration.
Finally, to complete the removal process, restart your Windows Server 2025. A reboot ensures that all processes and configurations are fully reset, and your server returns to its standard standalone operation.
By following these steps, you should be able to remove Azure Arc setup from your Windows Server 2025 with minimal disruption. This process ensures that your server returns to its original configuration without leaving behind unnecessary hybrid cloud configurations or dependencies.
Always keep in mind that Azure Arc offers significant benefits for hybrid cloud management, so consider whether removing it is necessary for your organization’s long-term goals before making any changes.
