Less than one year after being launched in preview and before leaving testing, the COPILOT function in Excel is going away. The function never shipped to general availability, but it could be used by Frontier and Insider users since August 2025.

The COPILOT function allowed users to use natural language to place prompts into spreadsheets. For example, you could use it to summarize text or categorize feedback. The function could also look up information from the web.

While useful, the function had serious limits. Microsoft stated that people should not use the COPILOT function for numerical calculations, responses that require context from other parts of a workbook, or any tasks with "legal, regulatory or compliance implications."

Considering how many people use Excel for important work and calculations, those limits are quite restrictive.

Microsoft's explanation of why the feature is going away lacks details. Instead, it primarily focuses on the fact that Copilot in Excel is still available in the side pane:

"Beginning September 14, 2026, the =COPILOT function in Microsoft Excel will no longer be available. This function is currently offered as a preview feature through the Insider and Frontier programs.

Customers can continue using Copilot in Excel through the Copilot side pane, which provides many of the same AI-powered capabilities, including summarizing text, classifying data, generating content, and retrieving information from the web. This change helps streamline the Copilot experience within Excel while continuing to provide AI assistance through a supported interface."

Users will not be able to create new formulas using the COPILOT function after September 14, 2026.

Windows Central take

It appears Microsoft may be reining in Copilot a bit. The AI tool is still part of the company's plans, but in a more controlled manner.

Microsoft has a unified Copilot experience that merges Copilot and Microsoft 365 Copilot. We've also seen some Copilot features go away or be limited over the last few months.

Earlier this summer I argued that the free version of Copilot is starting to feel like a tech demo designed to push paid tiers. I still think that's the case, but if Microsoft is going to push Copilot, it's best to do so with a plan.

Since the launch of Copilot, it's felt like Microsoft threw everything at the wall to see what sticks. The Copilot brand was diluted and there were dozens of different apps with Copilot in the name. Anything even remotely related to AI was attached to Copilot in some way, making the term almost meaningless.

Whether it's because Microsoft decided that strategy was a mistake or it's just had enough time to assess what properly stuck, the next wave of Copilot feels more targeted.

When does a bug become a feature? Microsoft needs to answer that question now that classic Outlook may hide the Copilot button and stop other Copilot features from working.

A bug that appears with build 20026.20182 of classic Outlook prevents access to Copilot Chat and removes Copilot entry points within the app.

"After classic Outlook for Windows updates to build 20026.20182 and higher, you no longer have Copilot Chat or Copilot entry points in Outlook," reads a Microsoft support document. "This issue happens if you have a Copilot Chat (Basic) license or a paid M365 Copilot (Premium) account."

While it's easy to joke about Copilot going missing being "addition by subtraction," the bug is likely frustrating for those that rely on Copilot within classic Outlook.

If your system is affected by the bug, the Copilot button could be missing from the top-right area above the ribbon. The Copilot icon can also go missing in the left app bar or the More Apps area.

Even if you see the Copilot icon in the Add Apps section, selecting "Open" may not do anything at all. Even if you've added Copilot through ribbon customization, the option may appear grayed out or unavailable.

Only classic Outlook is affected, meaning Copilot still appears and works as usual within the web version of Outlook and other versions. The Microsoft 365 Copilot app and web experience are also working normally, though it's worth noting Microsoft has a new unified Copilot experience rolling out.

If you need to use Copilot immediately, Microsoft suggests switching to Outlook on the web or the new Outlook app. While standard fixes like creating a new Outlook profile, clearing local cache data, re-signing into Office, or restarting Windows have been tried, Microsoft notes they don't consistently restore the missing buttons.

I have several PCs in my office that are capable of running Copilot+ tools in Windows 11, but there's one feature I've stayed away from: Windows Recall.

Why? I don't particularly like the idea of AI snapshotting what I do on my PC and making it searchable, even if it promises to never let the data leave my local system. I'm sure it's handy for some users, but I've yet to come across a scenario where I wish I had it enabled.

If you're of the opposite opinion and happen to use macOS, I have good news. OpenAI today announced "ChatGPT Computer History" for its macOS app.

What is ChatGPT Computer History?

It's tough not to immediately begin comparing Computer History to Windows 11's Copilot+ Recall feature.

Here's a blurb from the ChatGPT press release about how it works:

Yeah, that sounds like the same thing. But let me explain ChatGPT's version a bit more.

Computer History, according to ChatGPT's website, is completely optional and turned off by default for Pro, Business, and Enterprise subscribers.

Rather than collecting screenshots every so often to keep track of your doings, Computer History "records interaction events and does not capture your screen or audio." It's basically its own little keylogger, keeping tabs on clicks, typing, app switching, shortcuts, and more.

The data it records is searchable, and you can interact with Computer History the same way you interact with any AI, asking it regular language questions.

The data that Computer History gathers is saved locally on your Mac, but it does get sent to OpenAI's cloud servers in order to turn it into memories. These memories are then sent back to your Mac for local storage.

OpenAI says it does not keep this data on its servers unless required by law, and it does not use the data for training.

Is Computer History different enough from Recall to avoid similar backlash?

The reaction to ChatGPT's Computer History announcement is surely mixed. It seems like there are just as many people worrying about massive privacy and surveillance issues as there are people wondering if they should go out and buy a Mac.

Windows Recall faced the same adversity when it was announced as a default feature, with no opt-in available. The pushback was so bad that Microsoft delayed its launch by almost a year in order to address security issues. It officially released in April 2025 as an opt-in feature, but I know that many Windows users are still wary of its abilities.

The fact that ChatGPT is making its Computer History opt-in from the start tells me it learned from Microsoft's mistakes. There's also the fact that it doesn't take screenshots, making it feel less like routine spying.

That doesn't mean there aren't inherent risks to using something like Recall on Windows or Computer History on macOS.

It's clearly noted in OpenAI's Computer History documentation that the feature does not encrypt your information, and that it can be accessible to other apps running on macOS.

Like Recall, there are also serious prompt injection risks. Because these AI-powered features can essentially see what you're doing, they can be tricked with text. You might visit a seemingly innocuous website, only to realize later that it contained hidden instructions aimed at AI that made it do something unsavory.

Windows Central's take

Some of us here at Windows Central use Windows 11's Recall feature. Others don't. I'm in the latter camp, but one day that might change.

Why? It feels like there's a definite push going on with AI assistants that can remember everything you do, and it's not just ChatGPT and Microsoft. I've spent time with Lenovo's Qira cross-device ambient assistant, and I've written about HP IQ.

Although I shudder at the privacy implications of these tools gone wrong, they definitely seem like one strong fork in the future of computing. It will be interesting to see how this all plays out, and ultimately to see how macOS users react to something that made Windows users go ballistic.

What do you think about ChatGPT's Computer History? Is it Recall with a different name? Is ChatGPT approaching the tool properly with opt-in-only settings and no screenshotting? Is it something you'd use on Windows 11? Let me know in the comments section below!

Back in May, Microsoft confirmed that it was working on a Copilot super app that would merge the different consumer Copilot and productivity Copilot experiences under one app. Until now, Copilot and Microsoft 365 Copilot have been targeted at different users, but starting today those apps are being merged into one.

"We're updating Copilot to create a simpler, more cohesive experience for everyone," a new Microsoft Support document says. "Depending on the account and device you use, you will see changes to the Copilot app including changes to appearance and functionality, such as navigation, feature availability, or sign-in experience."

The unified Copilot experience begins its rollout today, but not everyone will see it right away. Microsoft says the experience will land on mobile first, with the unified Copilot on Windows and macOS being an opt-in experience at first, made available over the coming weeks.

The rollout should make it easier to move between using Copilot as an AI assistant for personal matters and using Copilot for productivity based tasks. For most people, not much will change with the unified app, which will simply appear as "Copilot" now. With that said, Microsoft does say that some features are going away with the unification. Those features include:

• Group Chat
  • All group chat threads, messages, and images will not carry forward after August 18, 2026.
  • Users must manually copy or download anything they want to keep.
• Podcasts
  • The Podcasts feature is being fully retired on August 18, 2026.
  • Users will no longer be able to create or access podcasts in Copilot after this date.
  • Individual podcast files can still be downloaded before retirement.
• Deep Research
  • Deep Research is being retired for consumer users starting August 18, 2026.
  • Existing Deep Research content will remain accessible, but the feature itself will no longer be available.

For those using Copilot with a work or school account, Microsoft says the unified Copilot app is also coming to those accounts too. The personal and commercial accounts will be separated within the app, meaning data from your work or school account won't be shared with your personal account, and vice versa. "Work and personal accounts remain separate. Your organization's security, privacy, compliance, and administrative controls continue to apply when you use Copilot with your work or school account."

For those using the personal consumer Copilot app, you will notice an updated UI that more similarly matches the Microsoft 365 Copilot app. Those who use the Microsoft 365 Copilot app likely won't notice much of a difference, outside of the rebranded app to just "Copilot," along with a slightly updated logo.

For those curious, this is the new Microsoft Copilot icon and branding. Can you tell the difference? No, us neither.

Lastly, Microsoft has confirmed that all your Copilot data (except for the features that are being taken away) will migrate automatically to the new experience, meaning users won't need to do anything to ensure their chats and data are carried forward. All of that will happen automatically when the unified app lands on your device.

The unified Copilot experience begins its rollout today, though it's happening in waves so most users won't see the changes right away. Worldwide rollout for the mobile starts today, with rollout for Windows and macOS expected to start in mid September. Here's the full rollout schedule:

• Mid‑August 2026 — Worldwide rollout begins for mobile and web apps; early‑access opt‑in opens for Windows and Mac apps; copilot.cloud.microsoft URL available in Frontier for testing.
• Late August 2026 — Standard rollout of the URL redirect begins.
• Mid‑September 2026 — Worldwide rollout begins for Windows and Mac apps.
• Late September 2026 — Deferred rollout of the URL redirect begins for the web app.

Microsoft's unification of Copilot is a long time coming, and one that is setting the company up to deliver a Copilot super app experience that can do everything across Microsoft's platforms and services. It never made sense for Microsoft to split Copilot up between consumer- and productivity-based use cases, especially since users commonly want to do both.

Twitch has another backlash on its hands, this time for forcibly opting-in all of its users to wanton content theft.

Twitch is a generally awful platform. The business has been a major drag on Amazon's bottom line since they acquired the brand losing billions of dollars year in, year out. Amazon has simply been unable to figure out how to adequately monetize the platform in a video streaming universe dominated by YouTube and Google ads, but its treatment of its userbase and content creators has hardly helped.

Indeed, Twitch is facing another backlash right now for forcibly opting users into "ai training." Now, when you stream on Twitch, by default your likeness, content, voice, and other interactions will be used to train Amazon's AI stuff, in a move nobody could've seen coming.

they know we don't want it. they do not care.

— @witchytq.bsky.social (@witchytq.bsky.social.bsky.social) 2026-08-12T22:25:50.671Z

Responding to the backlash, Twitch Chief Product Officer Mike Minton admitted that they knew everyone hates it, but they don't care.

"Why is not opt-in?" Minton responded, acknowledging Twitch's very angry chat during a live stream this past week. "I get it ... let me opt-in vs. making me opt out. The honest answer, and I think most of you can probably appreciate this ... if it was opt-in, nobody would opt-in. That's honestly the answer. It's gonna' be on by default."

You can opt out of Twitch's AI content theft machine by going to settings, security and privacy, then toggling off "training for generative AI."

The entire tech world seems steeped in AI psychosis right now, expecting us plebians to just sit down and take generative slop and its painfully useless and forced "features" flooding into every corner of the web. AI Nutjob-In-Chief Sam Altman recently was fried alive on X (Twitter) for suggesting parents use ChatGPT to generate podcasts for their kids, rather than simply ... yanno, talk to them.

The latest Twitch backlash is just another long list in self-defeating stuff the platform has implemented over the last few years. For what it's worth, competitor YouTube does not give creators any control whatsoever over whether or not their content is used for training. Your content on YouTube is used automatically for Gemini's video training. Google only lets you opt-out of "third-party" training. At least Twitch is giving users an opt out ... which is something, I suppose.

As the tech world struggles to figure out how to make any of this AI stuff make sense, I suspect we'll see more dumb stuff emerge from the gaming universe, not less, in the near term.
