Wednesday at 9am PT, 12pm ET, 5pm GMT, Thursday 4am AET Microsoft will be discussing more details on Windows 10—and we’ll be on site to bring you all the details. If you want to stay in the loop but can’t watch the livestream, keep your browsers pointed at this page: we’ll be liveblogging the event right here.

Gaming: With Phil Spencer in attendance, there should be some gaming-related announcements. DirectX 12 was announced last year at GDC and will be shipping with Windows 10 when it launches, and an Xbox app for Windows 10 has also been reportedly spotted—so we'll likely get more details on DirectX 12 and what it'll do for PC gaming, as well as just what that Xbox app is all about. We could also potentially hear something about broad support for cross-platform play, given Windows 10 taking the approach of being a single OS meant to cover multiple types of devices.

Continuum: This was the sort of feature that Windows 8/8.1 needed—the ability to switch between its touch-friendly interface and Desktop mode seamlessly depending on the type of device you’re running and what peripherals are attached. It wasn’t ready in time for the original tech preview release, so this would be a great time for more info to be revealed.

Microsoft’s needed to shed the negative connotations associated with Internet Explorer for a long time now, and a more Chrome-like browsing experience could do just that.

Cortana: The integration of a digital assistant into Windows 10’s operating system could signal an attempt on Microsoft’s part to broaden or shift how search is done within Windows. If it turns out you can use Cortana just like Siri to search for just about anything, be it info or files, such a feature could render standalone products like Amazon's Echo obsolete fairly quickly.

In the meantime, what can you expect? Here are a few key topics that are likely to crop up during the event:
