The New Xbox Experience powered by Windows 10, which launches this November for everyone, apparently takes up a whopping 1.5GB of your hard drive space, VG247 Italy reports. This makes it the biggest update for any game system ever yet.

It makes sense, too- the New Xbox Experience completely and thoroughly revamps the Xbox One UI, basing it off of Microsoft’s just launched Windows 10, in an attempt to address a lot of longstanding issues with the Xbox One interface. Early impressions from the beta have been positive, and the UI has been praised for being quick and far less obtuse than its predecessor. It’s essentially an all new OS rewrite- so it makes sense that it would be big.

Xbox One consoles ship with at least 500GB of on board storage, so there ideally shouldn’t be any issues with having enough space to install this- but still, if you have way too many games installed, maybe now would be a good time to do some spring cleaning.

This November, Microsoft will completely overhaul the Xbox One UI when they release the first new Xbox Experience for the console. The New Xbox Experience will be powered by Windows 10, and promises to significantly overhaul the user experience, addressing longstanding complaints about the Xbox One OS, and also addressing ease of use and streamlining. The New Xbox Experience is currently available to Xbox live members part of the Preview Program on Xbox One.

In this new video that you can see for yourself below, Larry Hryb sits down with Richard Irving on the Xbox engineering team to discuss the first preview of the New Xbox One experience for the Preview Program. They run through some of the salient features of the update, while also talking more in depth about what else is coming, as well as what has been moved or removed from the current setup (of which, the Live Window on the home screen seems to be the biggest casualty).
