 ## Uninstall and re-install the VMSnapshot extension on Windows operating system
 
+If you 're experiencing Azure VM backup or extension failure issues, uninstall and reinstall the `VMSnapshot` extension on a Windows VM. This extension is responsible for enabling application-consistent snapshots during backup operations. Since it’s a hidden extension, the process involves manually cleaning up registry entries and plugin folders, followed by restarting the Azure Guest Agent. After the registry is cleaned, the extension automatically reinstalls during the next backup job.
