 Update Management relies on the locally configured update repository to update supported Windows systems, either WSUS or Windows Update. Tools such as [System Center Updates Publisher](/configmgr/sum/tools/updates-publisher) allow you to import and publish custom updates with WSUS. This scenario allows Update Management to update machines that use Configuration Manager as their update repository with third-party software. To learn how to configure Updates Publisher, see [Install Updates Publisher](/configmgr/sum/tools/install-updates-publisher).

+## Update Windows Log Analytics agent to latest version 
+
+Update Management requires [Log Analytics agent](../../azure-monitor/agents/log-analytics-agent.md)  for its functioning. We recommend you to update Windows Log Analytics agent (also known as Windows Microsoft Monitoring Agent (MMA)) to the latest version to reduce security vulnerabilities and benefit from bug fixes. Log Analytics agent versions prior to [10.20.18053 (bundle) and 1.0.18053.0 (extension)](../../virtual-machines/extensions/oms-windows.md#agent-and-vm-extension-version) use an older method of certificate handling and hence it is not recommended. Older Windows Log Analytics agents would not be able to connect to Azure and Update Management would stop working on them. 
+
+You must update Log Analytics agent to the latest version, by following below steps:  
+
+Check the current version of Log Analytics agent for your machine:  Go to the installation path - *C:\ProgramFiles\Microsoft Monitoring Agent\Agent* and right-click on *HealthService.exe* to check **Properties**. In the **Details** tab, the field **Product version** provides version number of the Log Analytics agent. 
+
+If your Log Analytics agent version is prior to [10.20.18053 (bundle) and 1.0.18053.0 (extension)](../../virtual-machines/extensions/oms-windows.md#agent-and-vm-extension-version), upgrade to the latest version of the Windows Log Analytics agent, following these [guidelines](../../azure-monitor/agents/agent-manage.md).  
+
+>[!NOTE]
+> During the upgrade process, update management schedules might fail. Ensure to do this when there is no planned schedule.
