Microsoft will be holding a live-streamed event on February 8 to show off what's new for developers in the Creators Update. Dubbed Windows Developer Day, you can find out "what it means for your apps and games, and more about Microsoft’s latest developer products."
Kevin Gallo, director of the Windows Developer Platform, will be hosting the event alongside the Windows engineering team. They'll show off how the "latest advances in Windows 10 APIs and tooling will help you build great software".
Microsoft isn't holding its annual developer conference Build until May this year, which is a bit later than it usually is. It's likely that this is because the Creators Update is slated for April, so Build would focus on the next feature update, codenamed Redstone 3.
So instead of holding a major event to show off an update that we know almost everything about, it makes sense to have a small live-streamed show. You can RSVP for Windows Developer Day right now at its dedicated website.
