Watch the Microsoft Build 2024 keynote live here: More on Copilot+ and AI-enhanced PCs

The annual Microsoft Build developers officially conference kicks off today — but the tech giant has already revealed a laundry list of AI-centric hardware news. In a jam-packed Monday press conference, Microsoft unveiled one of the biggest changes to the Windows PC landscape in a long time. Copilot+ PCs, led by new Surface Laptop and Surface Pro models, are a promising new line of computers powered by Qualcomm Arm chips that enable significantly improved battery life without (if Microsoft is to be believed) the performance and compatibility compromises that have afflicted earlier Windows-on-Arm iterations over the past dozen or so years. Read our full wrap-up of the Surface/Copilot+ event for the details.

So what else does Microsoft have up its sleeve this week? Even more AI news, no doubt. With the hardware and Windows 11 news already on the board, CEO Satya Nadella and crew can provide even more detail on how the company's OpenAI partnership will further develop, and how Redmond will continue to counter Google's Gemini upgrades which were announced just last week.

You can follow along in real-time when the Build keynote starts Tuesday, May 21 at 12 PM ET/9 AM PT, and is scheduled to run for two hours. Watch the entire event live on YouTube (which is also embedded above) and at Microsoft's site (registration required).

If you want even more in-depth Microsoft Build news, there's also a second keynote session on Wednesday entitled Next generation AI for developers with the Microsoft Cloud. That one is scheduled for 11:30 AM ET/8:30 AM PT on May 22 and slated to run for 90 minutes.
