Computers of course aren't the only devices running Windows these days. The Xbox One's core was updated to Windows 10 last November. The already released Anniversary Update makes adjustments to the new UI and adds some new features. And let's not forget about Mobile, which benefits primarily from recent updates to the many apps of Windows.
Xbox One Updates
Similar to PCs, the Anniversary Update for the Xbox One brings a combination of new features, UI tweaks, and software improvements. The most noteworthy change in my opinion is the UI for My Games & Apps. These lists finally scroll vertically and you can fit as many as 30 tiles on screen at once. They can be sorted alphabetically in one pile, by letter like on a phone, last used, last updated, or by size. You have three options for the size of the tiles too. The headache of getting to your ready to install games and apps is nonexistent now with a dedicated tab added to the left column. It's baffling as to why it took so long for this to be updated, but it's finally here. Honestly, the only adjustment I'd like to see made is a separate list for Xbox 360 games.
Cortana is also on Xbox now, taking over the old voice commands if you so choose. Microsoft has leveraged their digital assistant here to enable users to use more natural language with voice commands. For example, you no longer have to say the full length of a game title in order to launch it, so instead of saying "Xbox go to Halo 5 Guardians" you can now say "Hey Cortana play Halo 5". And even if you don't have a Kinect, the new voice commands work through a headset as well.
The Cortana voice commands started working well only with the last major Preview release, so it's hard to compare using voice commands for a couple of days to a couple of years. But so far they seem to work about as well as the old ones for me, or in other words, most of the time. This Cortana has the same functionality as any other device running Windows 10, so she can do everything from checking the weather, to doing a web search, and even singing songs. That added functionality can potentially result in more problems however.
Having used Cortana for years now, I was fairly certain I could get it to fail. While watching tv, Cortana can change the channel to stations such as ESPN and CNN without issue. However, when I said "Hey Cortana watch HGTV," just as I had suspected, Cortana did a web search for "watch hgtv" instead of going to the channel. I even went into the OneGuide to favorite the channel, which on the old voice commands was supposed to help with similar failings, but I still got the same result. Thankfully, I haven't had any issues yet with Cortana responding while I'm playing a game to do things like recording game clips. If you decide you don't like using Cortana, there is an option in Settings to turn them off and go back to the old Kinect only Xbox voice commands.
And background music is back! It's only taken three years, but the secret best feature of the Xbox 360 is now on the Xbox One. The feature wasn't live at the time of this writing, but a new Groove Music app will soon be updated with this long requested feature. It's also open to third parties, with Pandora and the podcast app Cast available at launch. Playback controls will actually be found in the Guide, so no need to snap the app, or of course music can also be controlled via Cortana.
