Leaked materials from 2024 have revealed that Microsoft has built a working prototype Copilot OS that is platform agnostic, derived from the Microsoft Edge web browser and runs on top of Windows or Android, focused on the web and agentic experiences.
This project is codenamed Aion, and while its status is currently unknown, the leaked materials confirm that such a project was in active development and reached a stage in which the code was functional. With all the material leaked, we have a pretty good idea about how this OS experience looked and functioned.
According to the leaked materials, Aion is a UI shell built entirely with web tech, using a modified version of the Edge web browser. The interface is Edge, but altered to include desktop-like interfaces and functionality such as a Start menu, Taskbar, and cascading windows.
The documents confirm that Aion was capable of running on top of Windows 11 as a desktop shell replacement, or on AOSP Android. There's also a third compatible OS mentioned called Win3, which sources say was a special modified version of the Windows codebase with less legacy cruft, resulting in a lighter OS experience with faster boot times, longer battery life, and better security at the expense of legacy app support.
Aion seemingly wasn't compatible with legacy Windows apps, with the leaked video mentioning it only running web apps and websites, with tight Windows 365 integration for when users need access to a legacy Windows experience.
The Aion interface was built around Copilot and agentic AI experiences. It features a familiar looking Taskbar along the bottom of the interface, where the system tray and running apps appear. It also features a Start menu, except this time it's powered by Copilot and features a Copilot icon instead of a Windows one.
The Start menu is Copilot on Aion.MicrosoftIt runs web apps in floating windows, just like real apps.MicrosoftCopilot chats appear in their own floating windows with AI generated icons to match the topic.Microsoft
The Copilot Start menu is where users go to begin tasks, browse the web, or open web apps. The entire interface is built around Copilot, with users interacting with the OS via a multi-modal omnibox that can jumpstart tasks or workflows, find files, browse the web, initiate AI chat, and open web apps.
The new Start menu provides quick access to recent websites and files, and also groups recent activites into Spaces that let you launch multiple activities at once via a single click, curated by Copilot. Web apps will run in their own floating windows like real apps do on Windows, letting users cascade, minimize, and snap them.
The Spaces that Copilot curates also appear in the Taskbar when open. These appear as buckets, highlighted in a different color to let you know that these items are all being grouped together by the AI for picking up where you left off at a later point.
This is what Spaces look like on the TaskbarMicrosoftIf the user needs a legacy Windows app, Aion integrates with Windows 365 Cloud PCs to provide them.MicrosoftCertain actions can take place within a chat flow, such as sending an email.Microsoft
Because Aion only runs web apps, it's capable of understanding the context of everything you have open using Copilot. That means Copilot as an agent is capable of completing tasks on your behalf if asked by the user, and can answer any questions about the things that are open or were recently viewed at any time.
Aion also includes a feature that lets users complete tasks while staying in the flow of chat. For example, if the user wanted to send a summary of a web page to a friend or colleague via email, users could simply ask Copilot to do that, and the agent would pull in an email draft and let the user check it over and send it without ever leaving the Copilot chat interface.
It's unclear if Project Aion is ever intended to ship, or if it'll remain an internal experiment never to see the light of day. So far, we've not seen any official confirmation that a Copilot OS is going ahead. Microsoft recently announced Project Solara, an agentic OS that runs on Windows and Android codebases that utilizes a just-in-time UI approach to generate experiences on the fly.
While not the same, perhaps Microsoft has opted to go in a different direction for its agentic OS vision.

Honnêtement, avec la puissance actuelle de nos LLM, finalement, est-ce qu'on a encore besoin d'avoir des applications ?
Un outil type Claude Code ou Microsoft Copilot, à côté, un gros tas de données diverses et variées, quelques accès à des services et basta ! C'est peut-être ce vers quoi on se dirige, à notre grand détriment...
La preuve avec cette vidéo qui traîne sur le Discord de BetaWiki, tournée en 2024 et dont Microsoft ne dit mot. Des sources internes ont authentifié le clip pour le compte de
Windows Central
, le site qui a sorti l'affaire en premier. Dedans, un prototype d'OS baptisé Project Aion, où Copilot remplace le menu Démarrer, la barre des tâches et tout le shell classique. Il n'y a plus d'applications à lancer comme d'habitude mais une simple boîte de dialogue pour piloter votre machine, et c'est à peu près tout.
Le codebase porte le joli nom de Win3, Edge sert de shell, Chromium fait tourner le moteur de rendu et pour ouvrir un programme Win32 comme Word, Aion ne lance rien en local. Il vous renvoie en réalité vers une instance Windows Cloud PC semblable à
Windows 365
(C'est le Windows dans le cloud). Puis à côté, une boîte de saisie multimodale, des "Spaces" qui regroupent vos applis et vos sites web via l'IA, et des plugins capables de rédiger puis d'expédier vos mails Outlook tout seuls depuis un Space.
Le truc, c'est que Microsoft a déjà commencé à faire marche arrière sur Copilot ces derniers mois. Ils ont discrètement enterré l'intégration prévue dans les notifications et les paramètres de
Windows 11
, et Edge a même supprimé sa recherche d'historique par IA après la grogne des utilisateurs.
Du coup, Aion sent un peu le prototype qui a pris une bonne douche froide mais la direction officielle reste nette : IA PARTOUT ! Windows a même été officiellement présenté comme un OS pensé pour les agents IA et il y a actuellement plus de 80 produits Copilot dans le portefeuille de Microsoft, donc c'est loin d'être une lubie pour eux.
Par contre, côté public, l'accueil est glacial. Les gens ont vite compris qu'avec un OS comme celui-ci, plus aucune de nos applis locales ne tourneraient sans le cloud, que l'IA pourrait lire à travers tous nos Spaces d'un coup, sans parler du contrôle utilisateur qui fondrait comme neige au soleil... Vous allumez votre PC, et la moindre action ou fonction système transite par Copilot. Quelle déprime !
Mais bon, pas de panique non plus pour votre Windows 10 ou 11 puisque Aion ne sortira pas demain ni après-demain. De toute façon, Microsoft n'a rien annoncé. Par contre, cette petite fuite montre jusqu'où Redmond est prêt à aller pour tuer l'applicatif au profit d'une "conversation" globale avec l'IA. Putain, quel cauchemar quand on y pense...
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.

On Windows 11, if GIFs suddenly disappeared from the emoji panel, the problem wasn't caused by a broken update. It was caused by a service the operating system depended on quietly going away.
Starting June 30, 2026, users on versions 24H2, 25H2, and 26H1 began seeing a "GIF service is not available" message after pressing the Windows key + . (period) keyboard shortcut to open the emoji panel. Microsoft has now confirmed the issue affects devices that haven't installed its latest optional update, which replaces Google's Tenor service with GIPHY.
Why this happened
This wasn't a traditional bug with the operating system. The emoji panel relied on the Tenor API to search and display animated GIFs, but Google retired that service on June 30. Once the API was switched off, Windows 11 had nowhere to retrieve GIFs, leaving the feature effectively offline.
"Starting June 30, 2026, install the latest Windows update to continue using GIFs in the Emoji panel. If you don't update, you will see a 'GIF service is not available' error in the panel," Microsoft explains.
Instead of restoring Tenor, the company moved to GIPHY before the shutdown. Microsoft included the change in the June 23 preview update for versions 25H2 and 24H2 (KB5095093) and for version 26H1 (KB5095091), allowing updated systems to continue displaying GIFs without interruption.
Why GIFs may look different
The fix also changes the experience. Since Windows 11 now pulls results from GIPHY instead of Tenor, searches may return different animations, rankings, and content for the same keywords. The feature works the same way, but the library behind it has changed.

How to restore GIFs
If you're seeing this error, you can restore the functionality by installing the latest quality update from Settings > Windows Update. If you're doing this before the Patch Tuesday update release, then turn on the "Get the latest updates as soon as they're available" toggle switch.

Once the update is installed, the emoji panel automatically switches to GIPHY, and no additional configuration is required.
This is a reminder that even built-in features increasingly depend on online services outside Microsoft's control. When one of those services disappears, a feature that looks native to the operating system can stop working overnight until Microsoft rewires it to something else.
Windows Central's Take
On Windows 11, when a core feature suddenly stops working, the default reaction is usually to assume Microsoft broke something in the latest update. However, after tracking updates for years, I've learned that the operating system is often (not always) just caught in the crossfire of third-party service changes.
In this case, the company handled the transition as smoothly as it could. Instead of leaving users stranded, they already had a replacement lined up, and installing the latest update fixes the issue immediately. Just keep in mind that since GIPHY is taking over for Tenor, your typical reaction GIFs might look a bit different from now on.
Have you noticed any changes to the GIFs in the Windows 11 emoji panel, or are you still seeing Tenor? Let me know in the comments.

Microsoft is expected to announce another round of layoffs soon. Less than 2.5% of the company's workforce will be affected, according to sources that spoke with Business Insider. Due Microsoft's size, even that small percentage means thousands of people will be affected.
An SEC filing from June 30, 2025 showed Microsoft had about 228,000 employees. That figure has fluctuated since then, but it gives a gauge of the size of Microsoft's full-time workforce.
Division cuts & AI infrastructure
This round of layoffs will affect thousands of roles across sales, consulting, and within the Xbox division. Microsoft is expected to announce the layoffs next week, though plans are subject to change.
July layoffs have become commonplace for Microsoft because the company's fiscal year starts on July 1. Over 9,000 layoffs were made by Microsoft last July. Microsoft also lays off workers during other times of the year, such as the 6,000 layoffs made in May 2025.
Microsoft is one of many tech giants looking to reduce head count and lower expenses in certain areas. Increased AI spending and the rise of AI has affected jobs at several levels.
Voluntary retirements lowered the impact
This July will reportedly have fewer layoffs because several employees took voluntary retirement. Microsoft offered buyouts to employees level 67 and below in the United States who had 70 or more combined years of service and years of age (for example, someone who was 50 years old who had worked for Microsoft for 20 years).
Roughly 9,000 Microsoft employees were eligible for that buyout and around one third of those eligible took the buyout, according to Business Insider.
Xbox restructuring
Layoffs have been expected, and not simply because they've become an annual occurrence. Xbox CEO Asha Sharma is overseeing a restructuring of Xbox, much of which will occur within a 100-day reset.
As is the case with all layoff-related stories, I understand the business decisions that lead to layoffs but feel bad for the employees affected.

"Could have made some insane cash selling this, but no amount of money will stand between me and my determination against Microsoft." The company has since patched three zero-day exploits published by the security researcher, including YellowKey, GreenPlasma, and MiniPlasma.
More recently, Nightmare-Eclipse disclosed a new zero-day vulnerability dubbed RoguePlanet, which affects Microsoft Defender on both Windows 11 and Windows 10. The exploit could allow attackers to gain full control of affected systems (via Bleeping Computer).
Microsoft acknowledged the vulnerability and indicated that it's tracking the RoguePlanet zero-day exploit under CVE-2026-50656. According to the company:
"Microsoft is aware of an elevation of privilege in the Microsoft Malware Protection Engine in Microsoft Defender publicly referred to as "RoguePlanet ". We are working to provide a high quality security update that addresses this vulnerability. We will provide information in this CVE when the update is available."
The security sleuth shared a proof-of-concept exploit in a self-hosted Git repository, further claiming that Microsoft had scrapped its repository hosting exploits on GitHub and GitLab.
The exploit is a race condition, so it's a hit or miss. I have managed to get a 100% success rate on some machines while it struggled to work on others. The PoC for RoguePlanet works regardless if real time protection is on or not.
The statement seemed highly debatable in the community, though many still agreed with Microsoft's sentiments, including some of Windows Central's readers:
"It's not a secret, Windows Defender has been the best or near the best antivirus for years by now. Times when third-party antivirus actually served a purpose are long gone. You're just slowing down your system and paying for no reason."
In a subsequent blog post, Microsoft admitted that while Windows 11's Defender is usually enough for most users, third‑party tools add extra layers of protection, including identity monitoring or built-in VPNs.
