To what extent is it possible and legal to developer WinRT applications with VS2010 Pro?
On the one side, I think it should be perfectly possible and legal to create an HTML5/CSS/JavaScript WinRT App with VS2010 Pro since you can probably do so using Win 8 Notepad. On the other side, I think it might be difficult and possibly illegal to create an C# WinRT App via VS2010 Pro since doing so might require the user to circumvent intentional limitations of the VS2010 Pro software.
In the old days, the user just bought a stand alone compiler and she/he was free to link it against whatever libraries she/he choose. In this way, she/he didn't have to upgrade her/his compiler anytime she wanted a newer version of MFC or *.NET. These days, the IDE seems to be married to the compiler so I'm not sure if the user is allowed to use older IDEs (such as VS2010) to link against newer libraries like those offered in WinRT

See here.
You can use the Windows SDK, along with your chosen development environment, to write Windows Store apps (only on Windows 8)...
So it's clearly legal. I haven't tested it, but I'm going to guess that you can probably do the code side of things in VS 2010, but VS 2010 isn't setup to do Windows Store UI so xaml, html5 etc probably won't work.
It's probably much easier to simply use Visual Studio 2012 express.

It is not (directly). The APIs and the packaging tools will not be available in VS 2010.
While you could potentially do this yourself, it seems far simpler to just install Visual Studio 2012 Express for Windows 8 and use it.

It's more than just newer libraries - there's an entire new runtime, and the language needed changing in order to work with it.
