+To configure the agent to communicate to the service through a proxy server or remove this configuration after deployment, or use one of the following methods to complete this task.
+
+### Windows
+
+To set the proxy server environment variable, run the following command:
+
+```powershell
+# If a proxy server is needed, execute these commands with the proxy URL and port.
+[Environment]::SetEnvironmentVariable("https_proxy","http://{proxy-url}:{proxy-port}","Machine")
+$env:https_proxy = [System.Environment]::GetEnvironmentVariable("https_proxy","Machine")
+# For the changes to take effect, the agent service needs to be restarted after the proxy environment variable is set.
+Restart-Service -Name himds
+```
+
+To configure the agent to stop communicating through a proxy server, run the following command to remove the proxy server environmental variable and restart the agent service:
+
+```powershell
+[Environment]::SetEnvironmentVariable("https_proxy",$null,"Machine")
+$env:https_proxy = [System.Environment]::GetEnvironmentVariable("https_proxy","Machine")
+# For the changes to take effect, the agent service needs to be restarted after the proxy environment variable removed.
+Restart-Service -Name himds
+```
+
+### Linux
+
+To set the proxy server, run the following command from the directory you downloaded the agent installation package to:
+
+```bash
+# Reconfigure the connected machine agent and set the proxy server.
+bash ~/Install_linux_azcmagent.sh --proxy "{proxy-url}:{proxy-port}"
+```
+

+
+```bash
+sudo azcmagent_proxy remove

+- Learn how to manage your machine using [Azure Policy](../../governance/policy/overview.md), for such things as VM [guest configuration](../../governance/policy/concepts/guest-configuration.md), verifying the machine is reporting to the expected Log Analytics workspace, enable monitoring with [Azure Monitor with VMs](../../azure-monitor/insights/vminsights-enable-at-scale-policy.md), and much more.
+
+- Learn more about the [Log Analytics agent](../../azure-monitor/platform/log-analytics-agent.md). The Log Analytics agent for Windows and Linux is required when you want to proactively monitor the OS and workloads running on the machine, manage it using Automation runbooks or features like Update Management, or use other Azure services like [Azure Security Center](../../security-center/security-center-intro.md).
