At regular intervals, Microsoft holds 'Build' developer conferences (usually once a year, though not always) - and there's another one starting tomorrow, in San Francisco. Don't worry about not being there though, since you can watch any major announcements about Windows 10 (including 'Mobile') right on your computer via the URL below. What will be announced? We honestly have no idea, but expect more Windows 10 Redstone goodness in terms of APIs and UI innovations, plus a doubling down on both Universal applications and cross-platform apps and services (following the Xamarin acquisition).

Here's the Microsoft page announcing the livestream URL and here's the URL to visit tomorrow morning, USA Pacific time (so that would be 6pm onwards in the UK on British Summer Time.

Any major announcements will also be echoed at Microsoft's News Center.
