Vista - The Vista serial # sticker on the bottom

I have a laptop that is about three months old. The Vista product key is
worn off--all but the first four alpha-numerics.

Belarc gives me both the numeric (numbers-OEM-numbers) and the long
alpha-numeric number. It does not start out the same.

The question is can I upgrade from Home Premium to Ultimate using JUST the
internal numbers I have? It is a Toshiba OEM license.
Thanks,
Seth

Hi Seth,

This tutorial will show you how to use the free program "Windows Product Key Viewer" to see the real complete product key number used on your computer.

You will only be able to use the product key number for the same Vista version is was made for. Ultimate will require a different product key number for it than the one from your Home Premium. Sorry. You could contacts the OEM Toshiba to see of you can trade in your Home Premium for a discount on Ultimate. Sometimes they will give you a deal.
