We need our desktop application to determine the Windows Vista's edition,
e.g. whether application is installed on Ultimate, Home Premium, etc..

We have located this registry key in the Vista installation.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ProductName]

1) Will like to know what is the final product name that will be feedback on
this key for the 6 editions that Vista is going to have?

2) If this isn't a reliable way to obtain this information, please kindly
advise.

Regards,
Fred
 
I cannot answer this question but I would advice this: Home users who got XP
Pro OEM installed in their computer can only upgrade to Business or
Ultimate. Thus if you differentiate currently between XP and 2000/2003
users, the XP Pro users switching to Business (since MS doesn't allow update
to Home Premium) could be locked out of using your program in their home
computers.

I know several programs that are likely to run into this issue with
upgraders if they differentiate their versions between Vista Home/Business
editions. They would need to add a check that if the user has upraded from
XP Pro to Business then it would still be treated as before, not as if the
user was using a 2000/2003 Server.
 
There is something I'm missing here. Vista is still Vista, whether Home
Premium, Business, or Ultimate. It is Windows Server 2007/8 that is the
upgrade from 2003, not Vista.
