The reinstallation disks from Dell do NOT have the additional software on them.  Those are usually included on a separate disk(s). The only thing that differs between the Dell Windows 7 DVD and a Microsoft Windows 7 DVD is the OEM (Dell, in this case) branding stuff ... OEM background, OEM login screen, OEM badge in System Properties, and an OEM auto-activation mechanism so you don't/shouldn't have to enter your Product Key to activate it, etc..
Hello, I am new Dell Customer and just purchased my first Dell Inspiron 14 computer with Windows 7 pre-installed. How can I get a copy of the raw Windows 7 Operating System Installation discs? I want to re-install Windows 7 without the boatload of additional software that was installed on my system. I will also need to partition my disk and install other operating systems. So all I want is just a basic Windows 7 system. Thanks,
