  How come I didn't get a Windows disc with my new PC?   Because of Microsoft's bad policies. They have prevented Dell (or any other OEM) from shipping Windows Reinstallation DVDs with their systems. They have also failed to provide an installation .iso. This means all is lost if the system gets corrupt and installation media is not made in advance. You can still request the media from Dell by calling technical support and its best to do so while you've got warranty. You may also use the latest version of Dell Backup and Recovery to make a Reinstallation USB which will take you to factory settings: [URL]
