A leaked video has revealed that Microsoft has explored building a dedicated AI OS powered by Microsoft Edge and a new lightweight Windows codebase called Win3. This exploration was codenamed Aion, and was built around web tech, placing Copilot at the heart of the experience.

The 3 minute video, which my sources say is real, was first leaked on Discord server BetaWiki and provides a handy walkthrough of what looks to be real (but early) working code, showcasing a new desktop UI that features a similar Taskbar along the bottom, Start menu-like interface powered by Copilot, and more.

"Aion is an example of a web-based agent OS that natively builds Copilot into the core of the shell," says the video's narrator. The entire experience is built around Copilot and a multi-modal input box, which is where users go find files, open apps, and browse the web.

The Taskbar includes a unique feature called "Spaces" that automatically groups your apps and sites into a bucket on the Taskbar that you can quickly return to at a later point. These spaces appear in the Start menu too, providing a one-click method of opening multiple things at once.

The video explains that Aion is built around the web, meaning it doesn't run native Windows apps. It only runs web apps and websites, leaning on Windows 365 to remote into a Cloud PC and stream desktop apps if the user needs access to one.

The video does mention that there's a version of Aion that also runs on top of Windows 11, which would presumably support running Windows apps natively. But the version in the video appears to be based on the Win3 version, which sources tell me is a stripped back version of the Windows codebase that does not include support for legacy Win32 apps in exchange for faster updates, longer battery life, and better security.

My sources also say this video is quite old, recorded sometime in 2024, and it's unclear if this was just a Hackathon project or something more. I understand that Aion was experimental in nature, designed to explore what a desktop UX is capable of if built from scratch around an agentic AI. That means it's unclear if Aion is something that Microsoft ever intends to ship.

With that said, it would be surprising if some of the lessons Microsoft has learned from the Aion project aren't already shaping the version of Windows shipping today. While I don't expect Aion to ship as depicted in the video above, agentic OS capabilities are already finding their way into Windows 11.

Microsoft has also recently announced Project Solara, an agentic OS experience that utilizes just-in-time UI to generate experiences as the user asks for it. It runs on both AOSP and Windows, similar to Aion. Perhaps Aion evolved into Solara?

Either way, this is a fascinating look at what what at least one team thought the future of desktop computing could be like with Copilot at the heart of the experience. Given the sheer backlash around Copilot in the last year or two, I wouldn't be surprised if Microsoft is already rethinking much of this.

It looks like Microsoft's popular Surface Go and less popular Surface Laptop Go are on the chopping block. According to my sources that are familiar with Microsoft's hardware roadmap, these devices are no longer being manufactured, and no successors are currently planned

Just like the Surface Studio, Surface Laptop Studio, Surface Duo, Surface Hub, Surface Book, Surface Headphones, and Surface Earbuds before them, the Surface Go and Surface Laptop Go are the latest Surface PCs to reach the Microsoft graveyard, and completes the Surface portfolio culling that began in 2023.

Now, the Surface portfolio consists exclusively of Surface Pro and Surface Laptop, with varying screen sizes and power capabilities spread between them. Surface Pro features a 12-inch and 13-inch model, and the Surface Laptop features 13-inch, 13.8-inch, and 15-inch models with a special Ultra model coming this fall.

Sources say that Surface Go and Surface Laptop Go stock may still exist at certain retailers and in certain regions, but once that stock has depleted, it won't be replaced. When asked for comment, a Microsoft representative pointed me to the new Surface website, which notably doesn't include Surface Go or Laptop Go anymore.

Surface Go is a particularly surprising device to be killed off, as I understood that it was very popular with enterprise customers.

In fact, it was so popular with enterprises that Surface Go became a device exclusively for commercial customers with its final generation. Surface Go 1-3 were available for both consumers and commercial customers, but Surface Go 4 only ever saw a release for commercial customers.

Fascinatingly, I'm told Microsoft had planned to ship a Surface Go 5 at some point in the last couple of years, and it was going to be powered by a low-end Snapdragon chip. Unfortunately, when the company asked its enterprise customers for feedback, it found that most of them weren't interested in an Arm version of the device, and so that plan was scrapped.

Surface Laptop Go was pretty much replaced with the 13-inch Surface Laptop, which addressed the Laptop Go's biggest flaws such as the lack of a backlit keyboard and low-resolution display. Surface Go on the other hand hasn't really seen a replacement, as the 12-inch Surface Pro is significantly more expensive (and much larger) than the Surface Go 4 was at $579.

Of course, Surface Go originally launched at an astonishingly affordable $399 in 2018, albeit with very low-end specs that made the device hard to recommend. The Surface Go 3 and Surface Go 4 were the first versions with enough power to handle daily tasks without any noticeable performance loss, but their prices were much higher as a result.

I'm told that the decision to kill off these devices wasn't influenced by the ongoing RAMpocalypse, as the decision was made many months before memory prices became a problem for the company.

Now, the Surface portfolio is left with just two devices, Surface Pro and Surface Laptop. Many would argue these devices are no longer interesting or innovative from a form factor perspective, serving only to compete with whatever Apple is doing on their side of the fence. With Surface Laptop Ultra coming in the fall as a clear MacBook Pro competitor, this has never been more true.

Microsoft has issued a warning to all Windows 11 Home and Pro users still running the now two year old 24H2 release that support for this version of the OS is ending in just a few months.

All new versions of Windows 11 ship with a support window that lasts 24 months for consumers and 36 months for commercial customers. As 24H2 first launched in 2024, it's now coming to the end of its support window for consumers.

"Windows 11, version 24H2 Home and Pro editions will reach end of updates on October 13, 2026," Microsoft says in a recent update changelog. "Devices running these editions will no longer receive fixes for known issues, time zone updates, technical support, or monthly security and preview updates containing protections from the latest security threats."

The good news is everyone running 24H2 today should be fully compatible with 25H2, which is the current shipping version of Windows 11 and fully supported, based on the exact same codebase as 24H2. In fact, they're so similar, the 25H2 upgrade is very small and comes with no compatibility issues or complex update processes. It's essentially the flip of a switch.

That's the easiest fix for those still on 24H2 and worried about losing support. Once you upgrade to 25H2, you'll be fully supported once more until October 2027. If you want to wait until October this year, you can jump straight to 26H2 when that begins rolling out in the fall.

25H2 and the upcoming 26H2 release are based on the same platform release as 24H2, codenamed Germanium. This means the underlying OS doesn't change between the releases, only surface level features and changes are present between them. If you've been hanging onto 24H2 because you're worried about the upgrade breaking anything, there's really nothing to be concerned about. 25H2 is basically 24H2 part 2.

For commercial customers, there's not anything to worry about just yet. Windows 11 version 24H2 for commercial customers will continue to be supported until October 12, 2027, so over a year to go before those devices will need to be updated.

Microsoft has quietly announced that Windows 10's extended support updates program will continue for an extra year, now until October 2027 for free if you sign-in to Windows 10 with a Microsoft account.

Originally, Windows 10's extended support program was only supposed to last one year, until October 2026 for consumers. However, a new support page published by Microsoft today has confirmed that the Windows 10 ESU program will now last until October 2027 instead.

"Windows 10 support has ended. You can enroll in ESU any time until the programme ends on 12 October, 2027. If you’re already enrolled, your coverage will automatically continue through that date—no action needed," says the support page.

All Windows 10 users that are already enrolled in the ESU program will get this extended year of updates automatically. You can enroll in the program for free by signing in with a Microsoft account, or pay for access via 1,000 Microsoft reward points or $30 USD.

Microsoft has likely extended support for Windows 10 by an extra year due to the ongoing RAM crisis, which has pushed new PC prices through the roof making them difficult to justify financially, especially if you already have a working Windows 10 PC.

There are still hundreds of millions of PCs running Windows 10, and with extended support originally ending this October, many people would have been without the latest security patches keeping their devices secure.

The Windows 10 ESU program is vital to ensuring a PC that is connected to the internet is secure. Microsoft is still updating Windows 10 with security patches through the ESU program, and not being enrolled leaves your device open to attackers that might be trying to exploit vulnerabilities in the Windows 10 OS.

The good news is if you're already enrolled in the program, there's nothing you need to do to remain supported until October 2027. Your PC will keep getting security updates automatically until that date.
