Rafael offers up a way to enable Zune features that are disabled for those outside the US or Canada.

Welcome non-US/CA readers! There’s nothing more frustrating than buying a Zune, plugging it in, and discovering the software is “broken” because of how your computer is “configured”. Features like the Marketplace and that snazzy intro video? Completely missing! Yikes.

If you’re positive you should be seeing these features, don’t panic. Microsoft spent a lot of time programming some overrides for you. Simply navigate to HKCU\Software\Microsoft\Zune and create a key called FeaturesOverride. Within this key, create a DWORD for each feature you want to enable and set its value to 1.

He provides a list of features you can enable.

I was talking to him about this recently and apparently there is also a series of Registry entries related to Radio. Zune fans know that every Zune device since the original has supported some kind of radio receiver (FM and now HD Radio too in the Zune HD). But apparently Microsoft was going to (or soon will) enable Internet radio in the PC software too. I couldn't get it to appear in the UI, however.
