Problems with the keys

[john1]

Hello, I twist the RC of Windows 7 home Premium but absolutely no key work with this version. Work the keys only on the ultimate version?

As the legit DL's of 7 are all Ultimate by default the keys that were released will only work on ultimate.

Why don't you want to use ultimate anyway?

Thanks for the answer.
Because I since Vista use make of Home Premium.
