How to Use Microsoft Copilot in 2026: The Complete Beginner’s Guide

Microsoft’s AI assistant is now woven into Windows, Office, Edge, and your phone — but most people barely scratch the surface of what it can do. This guide explains how to use Microsoft Copilot from zero: where to find it, how to write prompts that actually work, and the features worth your time in 2026.

What Is Microsoft Copilot?

Copilot is Microsoft’s AI assistant, built on the same class of large language models that power ChatGPT. What makes it different is where it lives: instead of being a separate app you visit, Copilot is embedded in the tools you already use. It can summarize the Word document you’re reading, analyze the Excel spreadsheet you’re staring at, draft the email you’re avoiding, and answer questions about the webpage open in Edge.

There are two broad flavors. The free Copilot (at copilot.microsoft.com, in Windows, and in the mobile app) handles general questions, writing, and web-grounded answers. Copilot for Microsoft 365 — the paid business version — goes further, working directly inside Word, Excel, PowerPoint, Outlook, and Teams with access to your work documents, emails, and meetings. Most of this guide applies to the free version; we’ll flag where the paid tier unlocks more.

Where to Find Copilot

You probably already have access. Here’s where Copilot shows up:

• Windows: Press Win + C or click the Copilot icon on the taskbar. It opens as a side panel you can chat with while working.
• Web: Visit copilot.microsoft.com in any browser — no install needed.
• Mobile: Download the Microsoft Copilot app (iOS and Android). It supports voice conversations, so you can talk instead of typing.
• Edge: Click the Copilot icon in the sidebar to ask questions about the page you’re viewing — summarize articles, compare products, explain confusing passages.
• Microsoft 365 apps: In Word, Excel, PowerPoint, and Outlook (paid tier), Copilot appears as a side panel or inline button, working with the document in front of you.

How to Write Prompts That Actually Work

The difference between a useless answer and a great one is almost always the prompt. Five rules that transform your results:

1. Give it a role. Start with “Act as a hiring manager…” or “You’re an Excel expert…”. Roles focus the model’s tone, vocabulary, and priorities.

2. Provide context. “Write an email” gets you a generic email. “Write a polite follow-up email to a client who hasn’t replied in two weeks about a website redesign proposal; keep it under 120 words” gets you something you can actually send.

3. Specify the format. Ask for a table, bullet points, a step-by-step list, or a specific length. Copilot defaults to paragraphs; tell it what shape you want.

4. Iterate. The first answer is a draft, not a verdict. Follow up with “make it shorter,” “give me three alternatives,” or “explain that like I’m a beginner.” Conversations beat one-shot prompts.

5. Ask it to show its work. For anything factual, add “cite your sources” or ask “how confident are you in this?” Copilot can and does make mistakes — treat it like a smart intern, not an oracle.

Copilot in Word, Excel, PowerPoint, and Outlook

This is where the paid Microsoft 365 version earns its keep — Copilot works on your documents, not just the open web:

• Word: Draft documents from a one-line description (“draft a project proposal for a café website redesign”), rewrite paragraphs in a different tone, or summarize a 40-page report into key points.
• Excel: Describe what you want in plain English — “highlight the top 10 values in this column” or “create a pivot table showing sales by region” — and Copilot writes the formulas and builds the analysis. This alone is worth learning if spreadsheets intimidate you.
• PowerPoint: Turn a Word outline into a full slide deck, or ask Copilot to redesign your slides. It won’t replace a designer, but it kills the blank-slide problem.
• Outlook: Summarize long email threads in one click, draft replies in your voice, and get “coaching” suggestions that flag tone issues before you send something you’ll regret.
• Teams: Missed a meeting? Copilot recaps what happened, who said what, and what was decided — no more scrubbing through recordings.

Copilot vs ChatGPT: Which Should You Use?

The honest answer: they’re more similar than different under the hood, but they win in different places. Copilot’s killer advantage is integration — it’s inside Windows and Office, it searches the web by default, and it works with your files. ChatGPT’s advantage is broadth — a bigger ecosystem of custom GPTs, often earlier access to new model capabilities, and (as we covered when OpenAI started testing visual ads) a product that’s evolving fast in its own direction.

If you live in Microsoft’s world — Windows PC, Office documents, OneDrive storage — Copilot is the path of least resistance and usually the right choice. If you want the cutting edge of conversational AI as a standalone tool, ChatGPT remains the benchmark. Many power users keep both.

Copilot+ PCs: The Hardware Side

You may have seen the “Copilot+ PC” label on new laptops. These are Windows machines with a dedicated neural processing unit (NPU) — a chip designed specifically for AI tasks — enabling features like Recall (searchable snapshots of everything you’ve done), live captions with translation, and on-device image generation in Paint and Photos.

The catch: that dedicated AI silicon is part of why new laptops cost what they do. Our breakdown of 2026 PC prices explains how AI hardware, memory costs, and tariffs are pushing laptop prices up — worth reading before you buy a Copilot+ machine for features you might not use yet.

Practical advice: you don’t need a Copilot+ PC to use Copilot. The assistant runs in the cloud and works fine on any modern laptop. Buy the AI hardware for the local features (Recall, live translation); use the cloud Copilot for everything else.

Privacy and Limitations: What to Know

Three things to keep in mind before you pour your life into Copilot:

Your prompts may be used for training. On the free tier, Microsoft may use conversation data to improve its models. Don’t paste passwords, financial account numbers, or anything you wouldn’t want reviewed. Business-tier Copilot comes with enterprise data protections — your work data isn’t used for training.

It hallucinates. Copilot can state false information with total confidence — invented citations, wrong dates, plausible-sounding nonsense. For anything that matters (medical, legal, financial, or published work), verify independently.

It’s only as good as your files. The Microsoft 365 version’s superpower — answering questions about your documents — depends on those documents being in OneDrive or SharePoint. Scattered local files it can’t see are invisible to it.

5 Things to Try Today

Want a quick win? Try these in the next ten minutes:

1. Open Copilot in Windows (Win + C) and ask it to summarize a long article you have open in Edge.
2. Paste a messy paragraph and ask: “Rewrite this professionally, under 80 words.”
3. Ask: “Explain [a concept from your work] like I’m a smart 12-year-old.”
4. In Excel, describe an analysis you need in plain English and watch it build the formula.
5. On mobile, try a voice conversation — ask it to help plan something, like a trip itinerary or a week’s meal plan.

Going Further: Custom Instructions and Copilot Agents

Once the basics click, two power features are worth knowing about:

Custom instructions. In Copilot’s settings, you can set persistent instructions that apply to every conversation — your role, your preferred tone, how detailed you like answers. Set “I’m a small business owner; keep answers practical and concise” once, and every future chat starts from there. It’s the single highest-leverage setting most users never touch.

Copilot agents. For Microsoft 365 business users, the October 2026 updates are pushing “agents” — Copilot configurations that handle recurring workflows automatically, like triaging a shared inbox or summarizing a project folder weekly. This is also why IT departments are being told to migrate old SharePoint agents to the new Copilot Agent Builder before the March 2027 deadline for legacy .agent files. If your workplace runs on SharePoint, ask your admin what’s planned — agents built on the old format will simply stop working.

Microsoft Copilot FAQ

Is Microsoft Copilot free? Yes — the core assistant at copilot.microsoft.com, in Windows, Edge, and the mobile app is free with a Microsoft account. The deep Office integration (Word, Excel, PowerPoint, Outlook, Teams working on your documents) requires the paid Microsoft 365 business tier.

Does Copilot work offline? No. Copilot runs in Microsoft’s cloud, so you need an internet connection. Copilot+ PCs add some on-device AI features (live captions, Recall), but the assistant itself is cloud-powered.

Is Copilot better than ChatGPT? Neither is universally better. Copilot wins on integration with Windows and Office; ChatGPT wins as a standalone conversationalist with a larger customization ecosystem. Many people use both.

Can Copilot see my files? Only the files it has access to: the Microsoft 365 version can work with documents in your OneDrive and SharePoint. The free version can’t see your local files unless you upload or paste content into the chat.

The Bottom Line

Learning how to use Microsoft Copilot in 2026 isn’t about mastering a new app — it’s about building a new habit: asking the assistant that’s already sitting in your taskbar, your browser, and your Office apps. Start with the five prompt rules, try the quick wins above, and give it real context in your requests. The people getting transformative value from AI assistants aren’t using better models than you — they’re just asking better questions.
