Windows 7: Can you activate Home Premium with Professional code?

Can you activate Home Premium with Professional code?

So I'm really confused on this and have searched around but still have yet to find anything.

I am in the process of completing my first PC build (yay) and want to install Windows 7 Professional on it. The thing is, I already have Win7 Professional on my laptop, and I planned to transfer the license from the laptop to the desktop. The problem is, I cannot find my professional installation CD ANYWHERE. I looked all around and it just...isn't there. Both my dad and brother even said they never remembered seeing a professional CD anywhere (but I'm sure I had it...). Anyway, what I did find was a Windows 7 Home Premium UPGRADE CD.

So can I just use that home premium upgrade CD on the new PC, and then use the professional activation key? I'm a bit confused because I read that upgrade CDs must be used on vista/xp systems, but since my build is completely fresh, theres nothing on it.

Any help is greatly appreciated!

You can turn your Home Premium disk into a universal disk for any version:

Windows 7 Universal Installation Disc - Create

Keep in mind that the key must match the version you install. :)

One machine = 1 license.

1 license = 1 machine.

You will need two licenses.
