With the latest built of the Windows 10 technical preview, Cortana is making her desktop debut in a bunch more countries. As of build 10041 Windows Insiders in China, UK, Germany, Spain, France and Italy can use it.

The previous build limited Cortana support to just the United States, so there's now a whole lot more people who will be getting to try it out for the first time. It's a slow rollout still, but it's a great start and we'd expect this to continue as we get newer builds in the future.
