Microsoft on Tuesday said it disrupted a malware-signing-as-a-service (MSaaS) operation that weaponized the company's Artifact Signing system to deliver malicious code and conduct ransomware and other attacks, compromising thousands of machines and networks across the world. The tech giant attributed the activity to a threat actor it calls Fox Tempest, which it said offered the MSaaS scheme Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

Microsoft announced this week that it disrupted a malware-signing operation that helped cybercriminals distribute ransomware disguised as legitimate software. According to the company, a threat actor called Fox Tempest abused Microsoft Artifact Signing to generate short-lived code-signing certificates for malicious payloads.

Google is recasting its enterprise AI roadmap around autonomous systems and artificial general intelligence (AGI), with DeepMind CEO Demis Hassabis telling I/O attendees the industry now sits at the “foothills of the singularity.”

“When we look back at this time, I think we all realise that we were standing in the foothills of the singularity,” Hassabis said in his speech at Google I/O. “It will be a profound moment for humanity.”

The remarks capped a keynote spanning AI agents, cybersecurity systems, scientific research tools, coding platforms, and simulations — suggesting Google increasingly views AI not as standalone enterprise features, but as a broader operational platform capable of executing complex tasks across environments.

“AGI is now on the horizon, and it will be the most profound and impactful technology ever invented,” Hassabis said. “If built right, it could propel human progress and flourishing beyond our imaginations.”

While terms such as AGI and singularity have historically remained largely confined to AI research circles, Google’s keynote suggests those concepts are increasingly shaping how major vendors position long-term enterprise AI strategy.

Google pushes an agentic enterprise vision

Much of the enterprise AI market over the past two years has centered on copilots designed to assist employees with coding, productivity, and search tasks.

At I/O, however, Google repeatedly emphasized autonomous agents and long-running AI systems capable of orchestrating workflows, generating code, executing background tasks, and interacting across applications and environments.

Neil Shah, vice president for research and partner at Counterpoint Research, said Google is increasingly positioning its AI offerings as a unified enterprise platform rather than isolated AI tools.

“Google’s positioning to CIOs highlights its full AI stack capability powering a comprehensive enterprise-ready AI platform to build autonomous agent factories,” Shah said.

“Demis emphasizes that CIOs should look at this as a platform rather than singular AI tools to build their AI strategy,” he added.

That broader positioning was also reflected in Hassabis’ comments around AI safety and governance.

“It’s important that we are clear-eyed about the potential challenges and use all the tools at our disposal to ensure the safety of our agentic systems — and ultimately AGI itself,” Hassabis said.

Enterprise buyers face architecture and lock-in questions

For enterprise technology leaders, Google’s keynote may signal a broader shift from AI-assisted workflows toward increasingly autonomous enterprise architectures built around long-running agents and reasoning infrastructure.

Yugal Joshi, partner at Everest Group, said CIOs should interpret Google’s announcements less as a literal AGI prediction and more as a push toward “autonomous enterprise” architecture.

“Google wants them to use its platform not just for productivity and agents for specific tasks but to build end-to-end, well-orchestrated and governed agentic enterprise,” Joshi said.

The broader AGI framing could also reshape procurement and infrastructure decisions as enterprises commit more deeply to AI-native platforms.

“When a vendor positions their tech as a path to AGI, it is designing its AI strategy, which is future-proof but can introduce vendor lock-in, and that changes the math completely,” Shah said.

Cybersecurity and scientific AI emerge as proof points

Capabilities of AI models in cybersecurity are rapidly improving, with many now able to perform end-to-end, multi-stage penetration tests. These performance levels are doubling every five months or less.

Google sees a big opportunity here. “One area of risk that’s gained a lot of attention recently is cybersecurity,” Hassabis said in his speech, adding that Google is applying its “frontier capabilities and deep expertise to help secure the world’s code bases.”

Google introduced CodeMender, which Hassabis said can “automatically find and fix critical software vulnerabilities,” alongside a new CodeMender API for a select group of testers.

At the same time, Google heavily emphasized scientific discovery and simulation systems, areas Hassabis described as core long-term applications for AI.

“The whole reason I’ve worked on AI my entire career was because I saw it as the ultimate tool to advance science and our understanding of the world,” Hassabis said.

Hassabis also introduced Gemini for Science, a collection of AI tools designed to help researchers analyze papers, generate hypotheses, produce code, and accelerate scientific workflows. Google also highlighted simulation systems such as AlphaEarth Foundations and WeatherNext, which the company said improved hurricane prediction capabilities during the 2025 hurricane season.

The company further pointed to Isomorphic Labs, the Google-backed AI drug discovery company now working on treatments for immune disorders and cancer.

“Our mission is to reimagine the drug discovery process with the goal of one day solving all diseases,” Hassabis said.

While timelines surrounding AGI remain heavily debated, Google’s keynote suggests the company increasingly sees autonomous reasoning systems, rather than productivity copilots alone, as the long-term direction of enterprise AI.

Many years ago, Microsoft created a handy hub for its Office suite: type office.com into your browser, and you’d see a web page where you could launch the various Office apps — Word, Excel, PowerPoint, and so on — or access recently used documents in those apps. This hub’s appearance changed a bit over time as the Office suite was rebranded as Office 365 and then Microsoft 365, but it still served as a launch pad for your M365 files and apps.

Now, however, Microsoft has deeply integrated its Copilot generative AI assistant throughout Microsoft 365, and the hub has been transformed. Currently called the M365 Copilot app, the page puts the Copilot Chat interface front and center. You can still get to your M365 files or apps by clicking Search or Apps in the sidebar on the left, but the main purpose of the hub these days is to let you chat with Copilot.

The old Microsoft Office hub has been taken over by Copilot Chat.

With the rollout of new Word, Excel, and PowerPoint AI agents, you can use Copilot Chat in the M365 Copilot app to generate first-draft Word documents, Excel spreadsheets, and PowerPoint presentations. If you have a qualifying Microsoft subscription, you can also use the advanced Analyst agent in Copilot Chat to analyze M365 files in various ways. We’ll show you how.

In this article:

• Who can use Copilot Chat in the M365 Copilot app
• Create a document, spreadsheet, or presentation with Copilot Chat
• Analyze your M365 documents in Copilot Chat
• Get collaboration insights using Copilot Chat

Who can use Copilot Chat in the M365 Copilot app

As of mid-2026, Microsoft has integrated Copilot Chat into most M365 plans, which include:

• Microsoft 365 for individuals: Personal, Family, and Premium plans. Note that only the subscriber account has access to Copilot tools. They cannot be shared with other users on a Family or Premium plan.
• Microsoft 365 for business users: A basic version of Copilot Chat is included with the small-business M365 Business Basic, Standard, and Premium plans as well as enterprise-level Office 365 E1/E3/E5 and Microsoft 365 E3/E5/E7 plans. Add-on M365 Copilot licenses for small business and enterprise offer advanced Copilot features (these are included with the top-level M365 E7 plan).

Microsoft recently removed access to Copilot Chat from within Word and other M365 apps for large enterprise users who don’t have an add-on M365 Copilot license. That means the M365 Copilot app is now the only way for those users to access Copilot Chat.

If you don’t have a Microsoft 365 plan, you don’t have access to Copilot Chat. You can still use the M365 Copilot app to get to your Office files and apps, but if you click New chat, you’ll see a message saying that Copilot Chat requires an upgraded account.

In this guide, we’ll focus on using Copilot Chat in the M365 Copilot web app. There are also downloadable M365 Copilot apps for Windows, macOS, iOS, and Android. Depending on your M365 plan and computing environment, your interface may not exactly match the screenshots you see here, but it should work similarly.

Create a document, spreadsheet, or presentation with Copilot Chat

Using the M365 agents in Copilot Chat works mostly the same whether you’re creating a new Word document, Excel spreadsheet, or PowerPoint presentation.

1. Add the AI agents (if needed)

Depending on your Microsoft 365 plan and how it’s configured, you may or may not have the Word, Excel, and PowerPoint AI agents installed by default in Copilot Chat. If you don’t see them listed under “Agents” in the left sidebar, you’ll need to add them.

Click All agents in the left sidebar. You’ll be taken to the Agent Store, where you can browse through available agents built by Microsoft, third-party vendors, and/or your own organization. Type word into the search bar and select the Word (Agent) result that appears. A panel pops up with information about the agent.

Adding the Word agent to Copilot Chat.

Howard Wen / Foundry

Click Add to install the agent in Copilot Chat. It will appear in your Agents list in the left sidebar. Repeat the process for the Excel and PowerPoint agents.

2. Select the AI agent

On the Copilot Chat page, you first need to invoke a specific AI agent: In the left sidebar, select Word, PowerPoint, or Excel from the Agents list. (If you don’t see the agent you want, select All agents and then click on it.)

Alternatively, inside the Copilot chat box, type @ and select Word (or whichever agent you want) from the results that appear below the chat box.

Select the Word, PowerPoint, or Excel agent to get started.

Howard Wen / Foundry

3. Enter your prompt

Enter your prompt in the chat box, describing the details about the document, spreadsheet, or presentation that you want.

Example to generate a Word document:

• Create a document titled “Project Proposal.” Include sections for Executive Summary, Technical Requirements, and Budget. Use a formal business tone.

After invoking the agent, type in your prompt.

Howard Wen / Foundry

To generate an Excel spreadsheet, describe its structure. Example:

• Generate a sales report for Q4 2026. Include columns for Date, Product Name, Units Sold, and Total Revenue. Format the Revenue column as currency.

To generate a PowerPoint presentation, specify important aspects of the presentation, such as its topic, audience, number of slides, etc. Example:

• Build a presentation with 10 slides for a meeting announcing our new sustainability initiative. Include a slide for the timeline. Use an enthusiastic but professional tone.

4. Attach a file for reference (optional)

You can attach one or more files to the chat box for Copilot to use as reference when generating your request. For example, you can attach a Word document and prompt the PowerPoint agent to create a presentation based on it:

• Create a presentation from this document.

or have the Word agent create a document based on an Excel spreadsheet:

• Create a summary report based on the attached spreadsheet.

To attach a file, click the + icon on the chat box and select Add content (to attach a file in your OneDrive) or Upload files (to attach a file that’s on your local PC drive).

Alternatively, if the file is stored in your OneDrive, you can type / (forward slash) in the chat box and start typing its filename. This also pulls up a list of files recently added to your OneDrive that you can select from, and there’s also a search box you can use to find the file.

5. Review the generated result

When you’ve finished typing your prompt and optionally uploading a source file, press Enter or click the right-arrow button at the bottom right of the chat box.

The agent may ask you a few questions, mostly presented as options you select, before generating a result.

The PowerPoint agent typically asks a few questions about the presentation before it starts creating it.

Howard Wen / Foundry

Depending on the complexity of your prompt, Copilot will take several seconds to several minutes to generate a result. As it works, it will notify you of its progress.

Copilot will tell you what it’s doing as it prepares a result.

Howard Wen / Foundry

When it’s done, it will automatically save the document, spreadsheet, or presentation that it generated to the Documents folder in your OneDrive.

A large pane will also open in the right half of the screen, displaying the full document, spreadsheet, or presentation that Copilot generated. You can scroll vertically through it to review it.

The generated document appears in pane on the right.

Howard Wen / Foundry

Important: As always when using generative AI tools, check all results carefully for errors or fabrications. (See “How to curb hallucinations in Copilot” for tips on minimizing such errors.)

6. Refine the generated result

You can refine the generated result by entering a follow-up prompt in the chat box.

Example to refine a Word document:

• Add a section on Network Security, and make the tone more casual.

To refine a generated Excel spreadsheet or PowerPoint presentation, you have to first attach it to the chat box: Type the forward slash (“/”) in the chat box. This will pull up a list of files recently added to your OneDrive, including the generated spreadsheet or presentation. Select it and then enter your prompt to refine it.

Example to refine an Excel spreadsheet:

• Add a column titled Price Per Unit and calculate this value for every row.

width="654" height="461" sizes="auto, (max-width: 654px) 100vw, 654px">

To refine a generated Excel spreadsheet, attach the file and say how you want it changed.

Howard Wen / Foundry

Example to refine a PowerPoint presentation:

• Remove Slide 4. Add a blank slide at the end.

Copilot will generate a revised version. This will be saved as a new file in the Documents folder in your OneDrive.

7. Edit the generated result in a Microsoft 365 app

It’s best to think of genAI output as a template or first draft that you will update, add to, and otherwise tailor for your own needs. To do so, it’s easiest to open the generated file in the appropriate M365 app.

At the upper right, click Open in Word, Open in Excel, or Open in PowerPoint to launch the web version of that app in a new browser tab. The generated document, spreadsheet, or presentation will appear inside the app so you can do further work on it.

Analyze your M365 documents in Copilot Chat

You can use Copilot Chat to analyze your M365 documents in various ways by invoking the Analyst agent. This agent is available only if you have a Microsoft 365 Premium plan or, in a business environment, if you have an add-on M365 Copilot license. (That said, there is a workaround for the third tip below for those who don’t have an advanced license.)

In the left sidebar, select Analyst in the Agents list. (If you don’t see it, follow the instructions in step 1 above to add it.) Or, inside the Copilot chat box, type @analyst and press the Enter key.

Next, attach the file or files that you want Copilot to analyze. Click the + icon on the chat box and select Add content (to attach a file in your OneDrive) or Upload files (to attach a file that’s on your local PC drive).

Call up the Analyst agent and upload the files you want it to analyze.

Howard Wen / Foundry

Notes for Excel and PowerPoint files:

• Ensure that the data in an attached Excel file is formatted as a table. In this way, Copilot can better identify the range of values in it for analysis.
• For PowerPoint, the Analyst agent works best if your slide deck is text-heavy.

Here are a few ways you can have Copilot analyze your files:

Identify trends in data sets or presentations

Using the Analyst agent, Copilot can act as a data analyst, spotting patterns and anomalies in your Excel or PowerPoint files. It can also identify missing data that would provide a more complete picture.  

Tip: For the most accurate results, describe a specific source (such as the name of a table or slide numbers) and the timeframe to give the agent boundaries for its analysis.

PowerPoint example:

• Look at slides 4 through 8. What are the themes or trends in our sales?

Copilot Chat’s Analyst agent can surface key themes in a PowerPoint presentation.

Howard Wen / Foundry

Excel example:

• Show me the sales trends over the last month. Identify which product category is growing the fastest.

If your source file is missing the data Copilot needs for the trend analysis you’ve asked for, it will tell you so. It may instead provide a summary of the data the file does include and/or what can be inferred from the file’s data.

Copilot correctly says it can’t provide the requested analysis from the source data.

Howard Wen / Foundry

Project forecasts

The Analyst agent can use statistical models to project future values based on historical data in an Excel file. (These are simple projections and should not be presented as official forecasts.) Your source spreadsheet must include a time-based column, such as dates, and a numerical column for the values you want Copilot to forecast.

Example:

• Create a forecast for January based on the months of October, November, December in this spreadsheet.

Copilot has projected January sales based on the average growth rate from October to December.

Howard Wen / Foundry

You can also prompt the Analyst agent to create a projection based on an Excel spreadsheet and output it on a PowerPoint slide that you can download. Example:

• Create one slide that shows a sales forecast based on the months of October, November, December in this spreadsheet.

Howard Wen / Foundry

The agent explains how it calculated the forecast and offers suggestions for tweaking the result. Type whatever changes you want to make into the chat box, and Copilot will generate a new version of the slide.

Copilot explains what it did and suggests possible changes.

Howard Wen / Foundry

Compare document versions

Documents often go through multiple revisions, especially in a collaborative work environment. Unlike a basic versioning feature that lists literal differences, Copilot can provide contextual understanding and explain why a change is significant.

After you’ve attached two files to the chat box, enter a prompt, such as:

• Compare these two documents and highlight their key differences.

The Analyst agent summarizes the changes in the document’s overall direction and details the main differences in specific aspects of the document.

The Analyst agent explains how a document has changed overall, then cites key differences in areas such as title and positioning.

Howard Wen / Foundry

Note: If you don’t have access to the Analyst agent, you can alternatively try using the Word agent or the main Copilot Chat interface to compare two document versions. Like the Analyst agent, Copilot Chat presents its results in the chat window. If you use the Word agent, it creates a detailed comparison document after asking a series of questions about purpose, audience, and style.

Get collaboration insights using Copilot Chat

When working on a project with your co-workers, it can be a challenge to keep up with who did what to a file. You can prompt Copilot to list edits and comments to a file. This allows you to catch up on the context of changes without having to open it.

You don’t need to invoke the Analyst agent to do this. This works better if you use the main Copilot Chat. Click the + icon to attach the file (document, spreadsheet, presentation).

Optionally: At the upper-right corner, click Auto, which will open a dropdown. Here you can select an AI model that gives you results faster, or one that spends more time “thinking” in order to give you better-quality results. A second dropdown at the bottom lets you select a specific AI model by name, such as GPT-5.3 or GPT-5.4. We recommend picking a “think deeper” model for insights retrieval.

You can optionally pick a model for Copilot to use when it generates results.

Howard Wen / Foundry

Example prompts to extract collaboration insights:

• What has [CO-WORKER NAME] updated or commented on in this document?
• Summarize the comments and feedback left by everyone in this attached document.

Copilot will generate a detailed response based on your prompt.

Copilot can summarize who did what to a shared document.
