Watch Microsoft's Build 2015 keynote live here

Microsoft's Build developer conference kicks off today, and as you’d expect the focus will primarily be on Windows 10, although we’ll likely see new Windows hardware announced as well. Will a new Surface Pro 4 make an appearance? Probably not, but you never know.

The show, which takes place at the Moscone Center in San Francisco, runs from today through to Friday, but it’s the opening keynote that promises to be the most interesting.

We’ll find out more about Microsoft’s work on Windows 10, and universal apps, we should get confirmation of when the new OS is set to arrive (will it be July, or later in the summer?), and hopefully we’ll see more of HoloLens, Microsoft’s augmented reality system. It's rumored (quite strongly) that Microsoft will be introducing support for Android apps in Windows 10, which will be interesting, to say the least.

The keynote starts at 08:30 PST/16:30 BST today, but don’t worry if you haven’t been invited to the event, because as always you can watch the live stream right here.
