Product Key are specific to the Version, Edition, Language and Install method (i.e. Upgrade vs Full install and/or Retail vs OEM) of Windows it's to be used in.
Example: a Key for Windows 7 Ultimate English Upgrade would not be accepted in Vista Home Spanish Full install (or any other Windows that differed in Version, Edition, Language or install method)
Your key will still be valid for Windows 7 Home Premium Upgrade (i.e. it won't be deactivated) it just will not be accepted in any non-Windows 7 Home Premium copy of Windows.
Thank you,
