The Azure Virtual Machine Agent (VM Agent) provides useful features, such as local administrator password reset and script pushing. This article shows you how to install the VM Agent for an offline Windows virtual machine (VM).
When to use the VM Agent in offline mode
Install the VM Agent in offline mode when the VM Agent is not installed and you can't RDP to the VM.
Connect to the troubleshooter VM. Open Computer management > Disk management. Confirm that the OS disk is online and that drive letters are assigned to the disk partitions.
Step 2: Modify the OS disk to install the Azure VM Agent
Make a remote desktop connection to the troubleshooter VM.
In the troubleshooter VM, browse to the OS disk that you attached, open the \windows\system32\config folder. Copy all of the files in this folder as a backup, in case a rollback is required.
Select the HKEY_LOCAL_MACHINE key. On the menu, select File > Load Hive:
Browse to the \windows\system32\config\SYSTEM folder on the OS disk that you attached. For the name of the hive, enter BROKENSYSTEM. The new registry hive is displayed under the HKEY_LOCAL_MACHINE key.
Browse to the \windows\system32\config\SOFTWARE folder on the OS disk that you attached. For the name of the hive software, enter BROKENSOFTWARE.
If the Attached OS disk has the VM agent installed, perform a backup of the current configuration. If it does not have VM agent installed, move to the next step.
Rename the \windowsazure folder to \windowsazure.old.
Edit the registry files. In each file, change the entry value SYSTEM to BROKENSYSTEM (as shown in the following images) and save the file. Remember the ImagePath of the current VM agent. We will need to copy the corresponding folder to the attached OS disk.
Import the registry files into the repository by double-clicking each registry file.
Confirm that the following two subkeys are successfully imported into the BROKENSYSTEM hive:
WindowsAzureGuestAgent
RdAgent
Copy the installation folder of the current VM Agent to the attached OS disk:
On the OS disk that you attached, create a folder named WindowsAzure in the root path.
Go to C:\WindowsAzure on the troubleshooter VM, look for any folder with the name C:\WindowsAzure\GuestAgent_X.X.XXXX.XXX. Copy the GuestAgent folder that has latest version number from C:\WindowsAzure to the WindowsAzure folder in the attached OS disk. If you are not sure which folder should be copied, copy all GuestAgent folders. The following image shows an example of the GuestAgent folder that is copied to the attached OS disk. If you cannot find the GuestAgent folder, check for the imagePath of WindowsAzureGuestAgent registry subkey for the accurate path.
Select BROKENSYSTEM. From the menu, select File > Unload Hive.
Select BROKENSOFTWARE. From the menu, select File > Unload Hive.
Access the VM. Notice that the RdAgent is running and the logs are being generated.
If you created the VM by using the Resource Manager deployment model, you're done.
Use the ProvisionGuestAgent property for classic VMs
Important
Classic VMs will be retired on September 1, 2023
If you use IaaS resources from ASM, please complete your migration by September 1, 2023. We encourage you to make the switch sooner to take advantage of the many feature enhancements in Azure Resource Manager.
If you created the VM by using the classic model, use the Azure PowerShell module to update the ProvisionGuestAgent property. The property informs Azure that the VM has the VM Agent installed.
To set the ProvisionGuestAgent property, run the following commands in Azure PowerShell:
For a Windows VM, download the Windows VM Agent .msi file and install the VM Agent. For a Linux VM, you will install it from the github repository located at https://github.com/Azure/WALinuxAgent. For more information on how to install the VM Agent on Linux, see the Azure Linux VM Agent User Guide.

The Microsoft Azure Windows VM Agent is a secure, lightweight process that manages virtual machine (VM) interaction with the Azure fabric controller. The Azure Windows VM Agent has a primary role in enabling and executing Azure virtual machine extensions.
-Check if the VM agent is running on the virtual machine. You can do this by logging into the virtual machine and checking if the Windows Azure Guest Agent service is running. If it is not running, try starting the service manually.
In Windows, the 32-bit Azure CLI installs in C:\Program Files (x86)\Microsoft SDKs\Azure\CLI2 and the 64-bit in C:\Program Files\Microsoft SDKs\Azure\CLI2 . In Linux, the Azure CLI is installed in /opt/az/ on Ubuntu and Debian, and in /lib64/az/ on CentOS Stream, RHEL and Azure Linux.
Installs the agent by using a Windows MSI installer for Windows 10 and Windows 11 clients. Use Azure Policy to automatically install the agent on Azure virtual machines and Azure Arc-enabled servers and automatically associate them with required DCRs. To send data across tenants, you must first enable Azure Lighthouse.
Your Azure DevOps Server will now use the local files whenever the agents are updated. Each agent automatically updates itself when it runs a task that requires a newer version of the agent. But if you want to manually update some agents, right-click the pool, and then choose Update all agents.
To restart the agent, press Ctrl+C to stop the agent, and then run run.cmd to restart it. If you are running the agent from PowerShell Core to execute Windows PowerShell tasks, your pipeline may fail with an error such as Error in TypeData "System. Security.
Step 1: Attach the OS disk of the VM to another VM as a data disk. Take a snapshot for the OS disk of the affected VM, create a disk from the snapshot, and then attach the disk to a troubleshoot VM. ...
Step 2: Modify the OS disk to install the Azure VM Agent.
When your pipeline runs, the system begins one or more jobs. An agent is computing infrastructure with installed agent software that runs one job at a time. Azure Pipelines provides several different types of agents. Jobs can be run directly on the host machine of the agent or in a container.
The Azure Connected Machine agent enables you to manage your Windows and Linux machines hosted outside of Azure on your corporate network or other cloud providers. Warning. Only Connected Machine agent versions within the last 1 year are officially supported by the product group.
