Now that Microsoft Build 2026 is in the rearview, we have a much clearer picture of the future of Windows 11. Agentic AI systems! Smart work ID badges! Always-on personal assistants! The path ahead for Microsoft’s current operating system will clearly feature AI in some form or fashion at every turn. But what about Windows 12?
Though it wasn’t a surprise that Microsoft didn’t announce its next OS during this year's Build keynote, we’d be amazed if work on Windows 12 hasn’t been motoring away in the background for quite some time over in Redmond. As such, we thought now would be an opportune time to speculate on a platform that will likely usher in a new era of AI integration.
Whether dealing with the petaflop power of the Surface RTX Spark Dev Box or the potentially paradigm-shifting Project Solara, AI agents will be run both locally and through the cloud to forge next-level hybrid computing on Windows 12.
But it’s not all about AI with our predictions for an OS we’re expecting in the not-too-distant future. The future of Xbox could also be intrinsically tied to Windows 12. With Xbox Mode continuing to bloom on Windows 11, don’t be surprised if Microsoft commits hard to PC gaming going forward, with more focus on creating a UI that can truly compete with Steam.
Without further ado, let’s get into some Windows 12 predictions, even if it does seem ludicrously early to be making them.
Windows 12 will be all about AI
Forget Copilot. The level of AI integration Windows 12 is going to embrace will be far more impactful than asking a digital assistant what the weather will be in a couple of hours. Microsoft’s new OS will have AI baked into its very core, with agentic systems that exhibit real autonomy handling the jobs you’d previously have done with apps.
This year’s Build made it clear that AI agents are a huge priority for Microsoft. As much as they’re shaping the future of your current OS, the use of agentic systems will likely leap to a new level with Windows 12.
Just take Microsoft Scout. This new Autopilot AI agent acts as an always-on personal agent. Rather than needing to be prompted like Copilot, Scout uses the MAI-Thinking-1 reasoning model to act autonomously. As such, it learns how you work over time, quickly becoming aware of your routines in order to better service your needs on any given day.
By the time Windows 12 launches, Scout and similar agentic systems will have had plenty of time to percolate. When Microsoft’s next OS is out in the wild, we could be looking at a platform where AI runs far deeper than mere surface-level window dressing. The days of manually setting meetings or switching between spreadsheets and emails could be over, as AI agents like Scout take control of your workflow, autonomously handling tasks so that you can fully focus on the most important aspects of your job.
Essentially, Windows 12 is going to be an AI OS, one that could potentially transform the way you work.
Hybrid computing will be central to Windows 12
The era of AI PCs has been around for a while now, yet it looks like Windows 12 could fully realize the potential of AI, in part, by turning the focus more heavily on hybrid computing. In this future of Jaws 19, hoverboards and flying Deloreans, users won’t need to worry about whether tasks are running on their NPU, CPU or GPU. Instead, Windows 12’s AI-influenced OS will autonomously figure out where workloads should be handled.
This isn’t about Microsoft pitting cloud AI and local AI against each other. The future we envisage for Windows 12 is where hybrid workflows are commonplace, with AI agents running locally on the systems like the Spark Dev Box (which we’ll touch on shortly) and through the cloud, too.
Ideally, users won’t even know where tasks are running. Less demanding AI tasks may operate locally, while heavy duty rendering could be split up between hardware and cloud-based infrastructures. If Windows 12 fully embraces the concept of hybrid computing, the end result will hopefully be an OS that balances performance more efficiently, as tasks run discretely across local hardware and the cloud.
AI agents will replace apps
Much of the focus of this year’s Build centered around agentic systems. AI agents aren’t just the future of Windows, they’re the here and now. We’ve already touched on Microsoft Spark being rolled out to Frontier customers, and before too long Project Solara will be upon this.
Built from the ground up on a Microsoft-tailored Android platform, the focus for Solara is on AI agents, not apps. Indeed, Solara seems keen to move away from traditional Windows hardware, instead taking the forms of a smart clock-like device and a work ID badge. The latter has been designed to assist users on the go, and it’s capable of recording notes before using AI to clean up audio that can then be sent to colleagues. It potentially represents a future of computing where you no longer need to be chained to a laptop to get work done.
Microsoft is clearly betting the farm on AI, and it’s entirely possible Windows 12 will be a heavily AI-assisted OS. Unlike past operating systems, AI agents will have far more importance than old-school apps. In this (potentially soon to be realized) future, your day will no longer be taken up by sifting through emails and spreadsheets. Rather, agentic systems will act as personal AI assistants, acting autonomously as they help declutter your workday to help you complete tasks more effortlessly and efficiently.
Windows 12 will light the Spark
There’s a line of thinking that’s easy to buy into following Microsoft's Build keynote: Windows 12 will be a “dev-first” OS. Now, Redmond isn’t suddenly going to forget regular consumers. But looking forward, it’s hard not to see the Big M being more focused on servicing developers' needs than at any other point in its history.
Enter the Surface RTX Spark Dev Box. Initially shipping as a Windows 11 Pro mini PC that’s built around the Nvidia RTX Spark superchip, there’s no question more enhanced versions of this little rig will support Windows 12 in the future. Designed to support locally-based AI development, this is a box that has been built to service agentic workflows that eat up huge compute costs. Thankfully, the numbers suggest the Spark Dev Box will be more than capable of handling such tasks, as this dev-focused mini marvel gives users up to an astonishing 1 petaflop of AI compute and 128GB of unified memory.
Rocking the power of a combined Nvidia Blackwell RTX GPU and Nvidia Grace CPU, the Spark Dev Box can power 120B+ parameter models locally. And that last word really is key. Spark has been designed to service the most demanding local AI tasks, in turn taking the focus away from cloud-based AI pipelines. Spark feels like a test run for what the future of high-end Windows 12 devices will look like: a workstation where the emphasis is on locally supporting AI agents to give developers more control.
Xbox Mode could change the game
Microsoft didn’t shine any light on its gaming endeavors during the dev-focused Build keynote, and that wasn’t a surprise. That doesn’t mean there aren’t big plans for the future of Xbox, particularly with how it ties into Windows 12 going forward.
With Phil Spencer gone, replaced by new Head of Xbox Asha Sharma, don’t be shocked if Microsoft’s gaming division goes through big changes in the next couple of years. We’ve known about Project Helix for ages at this point. And with the next Xbox promising to bridge the gap between consoles and PCs like never before, how Windows 12 handles Microsoft games may look quite different to the way Windows 11 currently deals with Xbox titles.
Xbox Full Screen Mode rolled out on Windows not too long ago, giving gamers an experience that’s more in line with Steam’s Big Picture. As Xbox integration continues to evolve, it would make sense for Microsoft to double down on providing a more console-like OS for next-gen games.
As for what Xbox Mode on Windows 12 could look like, there’s a reasonable chance we could see a gaming-focused app that’s more deeply integrated with Microsoft’s next OS. Imagine a more streamlined platform that you could boot directly into as soon as you fire up your PC. One that uses fewer Windows background processes to provide an experience that’s every bit as seamless as Steam.
It seems clear the future of Xbox is more deeply tied to Windows than ever before. As rumors swirl suggesting Sony could soon stop releasing PS5 games on PC, next-gen Xbox titles could provide the most premium console-like experience on Windows 12.
