Windows 12 in 2026:
what is real, what is rumour,
and why the OS war just got interesting.

Windows 12 has not been announced. There is no release date, no public beta, no Insider channel, no confirmed feature list. According to Zac Bowden of Windows Central — whose Microsoft sourcing is among the most reliable in the industry — Windows 12 is not planned for 2026. He does not expect a product carrying that name before 2027 at the earliest, and even that is not a prediction of a 2027 launch.

Microsoft's confirmed roadmap for 2026 is Windows 11 version 26H2 — a major feature update for the second half of the year. That is the official story. Everything else is internal project names, leaked roadmaps, and analyst speculation. Worth reading. Not worth treating as a launch date.

What Project Hudson Valley actually is

Microsoft has been quietly trickling Windows 12 components into Windows 11 updates — the 25H2 and upcoming 26H2 releases. This is deliberate. Rather than shipping a new OS with new bugs, Microsoft is pre-seeding the architectural changes that will define the next generation, so that when Windows 12 eventually ships, the ecosystem is stable and the hardware is ready.

The central bet is the NPU — the Neural Processing Unit. In Windows 11, Copilot and AI features are add-ons running on the GPU. In Windows 12, the AI is the engine. The NPU is a dedicated processor for AI inference tasks — running language models, image recognition, real-time translation, and generative tasks locally without sending data to the cloud. Microsoft calls devices with NPUs "Copilot+ PCs" and has been requiring NPU support in new device certifications since 2024.

The architecture shift is significant. An OS built around an NPU can run AI features at a fraction of the power cost of GPU-based inference. It can do this continuously, in the background, without draining the battery or requiring a cloud connection. That changes what an operating system can do — not just as a feature list, but as a platform.

The OS war in September 2026 — where everyone stands

Why Windows 10's end of life matters more than Windows 12

Windows 10 reached end of support in October 2025. Millions of machines running it perfectly well were declared unsupported by Microsoft — not because the hardware failed, but because Windows 11's TPM 2.0 and CPU requirements excluded them. Those users had three choices: buy new hardware, pay for extended security updates, or find something else.

The "find something else" cohort is larger than Microsoft would like. Linux Mint downloads spiked in October and November 2025. Zorin OS reported that over 78% of its downloads in Q1 2026 came from Windows users. The Steam Deck had already made Linux gaming feel normal to an audience that would never have considered it two years earlier.

Microsoft's response — Windows 11 26H2 with expanded Copilot+ features and a path toward the NPU-native architecture of Windows 12 — is the right strategic answer. The execution risk is the same one that has followed every major Windows version: hardware requirements that exclude existing devices and push users toward competitors instead of upgrades.

What Windows 12 will actually need to be

For Windows 12 to succeed, it needs to do something Windows 11 failed to do: make the upgrade feel like a meaningful improvement rather than a compatibility barrier. Windows 11 added rounded corners, a centred taskbar, and Copilot. It excluded millions of perfectly capable PCs. The ratio of meaningful improvement to user friction was wrong.

Windows 12 has a genuine shot at getting this right — if the NPU integration delivers experiences that are clearly better than what Windows 11 can do. On-device AI that runs continuously, privately, at low power is a real differentiator. Real-time translation. Intelligent file organisation. Local summarisation without sending data to Microsoft's servers. These are things users actually want and that the NPU architecture can actually deliver.

The risk is the same as always: requiring hardware that most existing Windows users do not have, and calling that a feature rather than a migration. Microsoft has earned back some goodwill with the Windows 11 improvements in 24H2 and 25H2. Windows 12 needs to spend that goodwill wisely.

Which OS should you be on in September 2026

If you are on a Mac with Apple Silicon — update to macOS Golden Gate when it ships around September 14. Apple's on-device AI story is the most coherent of any platform right now. The M-series chip's unified memory handles AI inference without a separate NPU. It just works.

If you are on Windows 11 — stay there. Windows 12 is not coming this year and Windows 11 26H2 will bring meaningful improvements. If you are on a Copilot+ certified device, the NPU features being added in 26H2 are worth paying attention to. If you are not on Copilot+, manage expectations accordingly.

If you are on Windows 10 — this is the moment. Extended support ended in October 2025. You are running an unsupported OS. Your options are: upgrade to Windows 11 if your hardware qualifies, consider whether Linux Mint offers a better outcome on your existing hardware, or budget for new hardware. Staying on Windows 10 is no longer a neutral choice.

If you are considering Linux — Linux Mint 22.3 on a fresh install is a genuinely good experience in 2026 for everyday computing. Gaming on Linux has improved dramatically thanks to Proton and the Steam Deck ecosystem. The terminal is not as scary as it was. If you wiped a laptop and installed Mint fresh, you would be productive within an hour. We covered this in detail in the Linux 2026 article.
