Cómo identificar que instalación está pendiente de un reinicio

Updates packaged using the Windows Installer (MSI) are also not evaluated by this check. The registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations can sometimes be used to determine whether a restart is required. If this key exists and has files listed within it, a restart is pending.
