The short and sobering answer is (as of October 21, 2025): There is no official announcement or confirmation from Microsoft for a product called “Windows 12.”

The strong rumors predicting a release in 2024 or, at the latest, fall 2025, have not come to pass. These rumors were often fueled by hardware partners and insider reports suggesting a new three-year cycle for major Windows versions.

Instead of a big “Big Bang” release of a new operating system, Microsoft is clearly pursuing a different strategy.

The Reality: What Happened in 2025 Instead

While the world waited for “Windows 12,” Microsoft focused its energy on two main areas:

• Windows 11 24H2 and 25H2: The “AI Update” The “next generation of Windows” that Microsoft referred to wasn’t a new product, but a massive content update for Windows 11. The features originally attributed to “Windows 12” are now part of the major updates for Windows 11 (version 24H2 and the recently released 25H2).
• Windows 11 24H2 and 25H2: The “next generation of Windows” that Microsoft referred to wasn’t a new product, but a massive content update for Windows 11. This includes:
• Deep Copilot Integration: The AI ​​assistant is now an integral part of the system, not just a pinned app.
• New Copilot+ PC Features: Features like Recall (a searchable timeline of your PC activity) have been introduced.
• Optimization for NPUs (Neural Processing Units): The system is now designed to run AI tasks directly on specialized processors (in new “AI PCs”) instead of in the cloud.

Essentially, Microsoft has packaged the “Windows 12” revolution as an evolution of Windows 11.

Windows Server 2025: The only officially new operating system version Microsoft released this year is Windows Server 2025. While it includes a desktop environment similar to Windows 11, it is clearly designed for enterprise customers and data centers.

Current developments strongly suggest that Microsoft is moving away from the idea of ​​fixed, numbered versions – a strategy they originally intended to pursue with Windows 10 (“The last version of Windows”).

Instead of creating a new, expensively marketed product every three years, the focus now seems to be on Windows 11 as a continuous “service.” Once a year (in the fall), there is a major update (such as 24H2 or 25H2) that brings significant new features.

This approach has advantages:

• No fragmentation: Users don’t have to consider whether to upgrade to “12.”
• Stability: The core structure remains Windows 11, while AI features are added modularly.
• No major upgrade hurdles: The system requirements (TPM 2.0, etc.) remain the same as for Windows 11.

Outlook: Will “Windows 12” perhaps arrive in 2026?

Just because it didn’t appear in 2025 doesn’t mean the name “Windows 12” is off the table forever. Some reports (including one from PCMasters.de) speculate that Microsoft may have postponed the release to 2026 to further advance the development of AI features. It is conceivable that Microsoft will eventually make a clean break and brand the next major feature update (perhaps 26H2) as “Windows 12” to signal a clear new beginning – especially if the underlying system architecture (keyword “CorePC” for more modular systems) changes significantly.

If you’ve been waiting for “Windows 12,” the latest development is that you don’t have to wait. The “future of Windows” is already here; it’s simply called Windows 11 25H2.

The most exciting innovations are currently happening under the hood, with a strong focus on artificial intelligence. For Windows 10 users, however, the pressure is real: since support ended on October 14, 2025, the recommended step is not to wait for Windows 12, but to upgrade to the current Windows 11.
