Windows 7 Professional English 64bit (Includes Windows 10 Pro License)

I recently purchased a Dell and the only way the hardware options I wanted would come is if the OS was Windows 7 Pro with an included Windows 10 Pro License.  So I received the computer and I would like to upgrade it from the start.  However, I can't seem to find instructions on how to do this.

I have looked at the How to Set Up your new Dell Computer on the Knowledgebase, but it does not mention my situation.

I have looked at the Windows 10 Upgrade Walkthrough on the Knowledgebase. But it does not mention my situation.

I have tried the WIndows 10 Downgrade System on the Knowledgebase, but again it does not mention my situation.

The computer came with a purple CD that sys to ensure that the BIOS setting is set to UEFI mode prior to installing Windows 10.  But if I adjust this setting and run the CD there is no mention about upgrading to Windows 10 in the options available.

The Windows 10 Upgrade walkthrough talks about updating the Windows 7 install with Service Pack 1, but none of the info that came with the PC shows an upgrade code which I would probably need since the Microsoft free upgrade time period has expired.

So how to I upgrade this new computer to windows 10?  Just wondering what info I am missing.  I assumed this would be simple.  I shouldn't have to reinstall all my preinstalled software and drivers on a brand new computer on day one.

Thanks,
