Use the following command to identify the UUID of a machine that you want to remove from management.
az vm show -g MyResourceGroup -n MyVm -d
In the Azure portal, navigate to Log Analytics workspaces. Select your workspace from the list.
In your Log Analytics workspace, select Logs and then and choose Query explorer from the top actions menu.
From Query explorer in the right-hand pane, expand Saved Queries\Updates and select the saved search query
MicrosoftDefaultComputerGroupto edit it.
In the query editor, review the query and find the UUID for the VM. Remove the UUID for the VM and repeat the steps for any other VMs you want to remove.
Save the saved search when you're finished editing it by selecting Save from the top bar.
Machines are still shown after you have unenrolled them because we report on all machines assessed in the last 24 hours. After removing the machine, you need to wait 24 hours before they are no longer listed.
To re-enable managing your virtual machine, see Enable Update Management by browsing the Azure portal or Enable Update Management from an Azure VM.
