Hi People.
I just want to clarify, I have had my laptop for 3 months now. So if I make a media recovery disc using the Dell Recovery & Backup now, it should only record the factory standards; how I got it out of the box on the disc right? Not any current information or data I have put onto the laptop since opening it from the box?
All this stuff confuses me. Really want to restore my laptop to out of box standards but I need to do the disc first, as I did not know this and didn't realize I had to do it when I first received the laptop. 
Not sure if its any importance, I am from Australia, so I don't think I can get the media from Dell themselves. My laptop is still under warranty though until 2/5/2016.
Thank you for any help in advance!!
