Microsoft has revealed what's new in the just released Windows 10 PC preview build 14279 for Insiders in the Fast ring. It includes more languages for the Cortana digital assistant.

According to Microsoft's Windows Insider leader Gabriel Aul:

  • Cortana in more languages: With this build, we are enabling Cortana for the Spanish (Mexico), Portuguese (Brazil) or French (Canada) languages! If you're running the Windows 10 Insider Preview in these languages – give Cortana a try and let us know what you think. For each new market and language, the Cortana Team works to develop a custom experience that is relevant in each individual market and language. For instance, in Brazil – Cortana is fond of pasteis which is a common food found in many regions across Brazil. And in Mexico, we added local flavor to reflect the accent and language of the country. But our work is never complete and a big part of our development process is getting feedback from you. These are early versions that we will continue improve based on your feedback and we look forward to hearing more from you.
  • Cortana remembers things for you: We have all had those moments throughout a busy day where we need to remember something, but don't have time to stop what we are doing to set a detailed reminder. With Cortana, you can now save useful information like the name of a book you want to read (ex: "remind me to read [insert book name]"), or a to-do item without a due date (ex: "remind me to wash the car"). You have the option to set specific details like location, time, and people at a later time so that Cortana will surface it when its most relevant. You can always view and edit all of these in the same place you see your reminders in Cortana today. In future builds Cortana will be able to retrieve these upon request, just like a real personal assistant would.
  • Updated logon experience: Previously on PC, there were two separate backgrounds for the Lock screen and then the logon screen. We're merging the experience so there is just a single background – your Lock screen background. This is similar to the behavior seen on mobile. If you have a custom Lock screen background set, you will see your Lock screen background is now used for both the Lock screen and logon screen. If you're a Windows Spotlight user – hold tight, you'll see this change soon in a future build. We're also working on some additional tweaks here to make the transition between the Lock screen and logging in much smoother.
  • Performance and Candidate improvements in Japanese IME: We have improved performance of IME especially on typing response. So your typing experience will be smoother than before. We also extended our prediction content and you can select wider variety of candidates from prediction candidate list.
