Now that we're finally starting to dig into the Windows 10 Technical Preview for phones, we're unearthing some more details on what you can and can't do with this first build. Take Cortana , for example. As with the desktop preview of Windows 10, Cortana seemingly hasn't make the trip around the world.

The image up top is what we're currently seeing in the UK. The incredibly faint text reads "Cortana is not available in your market." Something else to think about if you're thinking of firing up the preview and you're a heavy Cortana user that isn't in the States. We've not yet tried any region tricks to see if it comes back, but officially, it doesn't seem to be there.

It's a shame, but it'll come back in a later build no doubts. But for now, it's back to doing things the old fashioned way.
