[H] Win8.1 question?

[DSinc]

OK, so I bought Windows 8.1 also. It arrived this afternoon.
Contains 2 DVDs (32-bit and 64-bit). OK, fine.
But the package says 'Full version.'
Can someone define just what 'Full version' really means to me?
Yes, was a retail purchase.
I was hoping for Win8.1 Professional. Not sure I got it............?
Thanks,
Duncan
