Is it possible to remove/uninstall update centrally from Azure Update Manager ?

Question

Is it possible to remove/uninstall update centrally from Azure Update Manager if it's already installed on VM ? I know for exclusions, but e.g. we install update and it's causing troubles, is it possible to remove it not by connecting to a VM itself and then manually unistall it?

Thank you,

Regards.

Hi @Vedran Banjeglav ,

This script uninstalls a specific Windows update (KB4589208) from a list of virtual machines (VMs) .It iterates through each VM, retrieves its resource group and name, and uses the Invoke-AzVMRunCommand to run a PowerShell command to uninstall the update. If the command fails, it catches and logs the error.

$vms= @( "vm1", "vm02")
 $KB= "4589208"
 foreach ($vm in $vms) {
 $Temp= get-azvm|?{$_.Name -eq $vm}
 $resourceGroupName = $Temp.ResourceGroupName
 $vmName = $Temp.Name
 Write-Output "Uninstalling update on VM: $vmName in Resource Group: $resourceGroupName"
 try {
 Invoke-AzVMRunCommand -ResourceGroupName $resourceGroupName -VMName $vmName -CommandId 'RunPowerShellScript' -ScriptString "wusa /uninstall /kb:$KB /quiet /norestart"
 Write-Output "Update uninstall command sent to VM: $vmName"
 } catch {
 Write-Output "Failed to send command to VM: $vmName. Error: $_"
 }
}
