How to know which edition of vs2010 do I have installed?

Question

I've seen How can I check what version/edition of Visual Studio is installed programmatically?, but the question remains, what will I find if the version installed is the 2010 Ultimate or Premium?

The answer selected as correct says "go to the registry and find":

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[version]\Setup\VS\[edition]

Where [version] can be:

• For Visual Studio 2005: 8.0
• For Visual Studio 2008: 9.0
• For Visual Studio 2010: 10.0
• For Visual Studio 2012: 11.0

And [edition] can be:

• For the Standard Edition: Std
• For the Professional Edition: Pro
• For the Team Edition for Software Architects: VSTA
• For the Team Edition for Software Testers: VSTT
• For the Team Edition for Software Developers: VSTD
• For the Team Suite Edition: VSTS
• For the Premier Partner Edition (2005) or Shell Edition (2008): IDE
• For the Visual Studio 2005 Tools for the Microsoft Office System: VSTO

But it does not speak of Premium or Ultimate editions released (that I know of) for 2010 and 2012 at least.

Answer 1

Ok so I went to the registry on a machine with 2010 Ultimate and on

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Setup\VS\

I've only found VSTS so, Ultimate is covered.

VSTS is the name of Ultimate in the registry

(But premium is still a question).

(And that's why this isnt an accepted answer yet).
