-# Slow Azure Virtual Machine Start operations caused by extensions being in a failed state
+# Slow Azure VM Start operations when extensions are "Failed"
 
 ## Overview
 
-You may experience slow Azure Virtual Machine (VM) **Start** or **Redeploy**
-operations when one or more of the VM extensions are in a **Failed** state.
-This article will cover possible causes and resolutions.
+You might experience slow Microsoft Azure Virtual Machine (VM) **Start** or **Redeploy** operations when one or more of the VM extensions are in a **Failed** state. This article discusses possible causes of this issue and resolutions.
 
-## Symptom
+## Symptoms
 
-In this scenario, the VM's guest OS can be active and working and the
-VM can connect successfully, but the operation is still appearing to run
-in the Azure portal.
+Although the Azure VM guest OS is active and working, and the VM can connect successfully, the operation still appears to run in the Azure portal.
 
 ## Cause
 
-VM extensions are software components that run inside the VM to enable
-configuration management, security, monitoring, and other features. VM
-extensions have a 90-minute provisioning timeout, which means they must
-complete their installation or update within that time limit. If an
-extension fails to provision within the timeout, it will be marked as
-failed and will not be retried until the next VM operation that triggers
-the extension, such as a **Start** or a **Redeploy**.
+VM extensions are software components that run inside the VM to enable configuration management, security, monitoring, and other features. VM extensions have a 90-minute provisioning timeout. They must complete their installation or update within that time limit. If an extension doesn't provision within the timeout period, it's marked as failed. The extension isn't retried until the next VM operation that triggers it, such as **Start** or **Redeploy**.
 
-When a VM has one or more extensions in a failed state, it can cause
-delays in other VM operations, such as **Start** or **Redeploy** because the Azure
-platform will try to provision the failed extensions again before
-completing the operation. This can result in the VMs showing a **Starting**
-status for an extended period.
+If a VM has one or more extensions in a **Failed** state, delays can occur in other VM operations, such as **Start** or **Redeploy**. This issue occurs because the Azure platform tries to provision the failed extensions again before it completes the operation. Therefore, the VMs show a **Starting** status for an extended period.

+To mitigate this issue, follow these steps:
 
-1. Review the extension status and logs for the VM to determine the
-    root cause of the failure.
+1. To determine the root cause of the failure, review the extension status and logs for the VM.
 
-    - To check the status of the extensions installed on the VM, go to the
-      VM Blade and select the **extensions + applications** option under
-      **Settings** in the left-hand pane. If the status is not **Provisioning Succeeded**, the extension may need to be removed or further investigation may be required.
