The short version
On Windows 11, Copilot is one key press away, and it can see what you show it. Press the Copilot key (or Windows key + C), ask your question, and attach a screenshot or a file from your PC when the question is about something specific.
Step by step
- Open Copilot. Press the Copilot key, use Windows key + C, or select Copilot on the taskbar or Start menu. Depending on your settings, it opens the full app or a smaller quick view.
- Sign in. Use a personal Microsoft account or a work or school account. Microsoft says a personal account unlocks chat history, image creation, longer conversations and voice.
- Ask your question in the box.
- Show it your screen. Select + in the box, then Take a Screenshot, and mark the area you’re asking about.
- Ask about your files. Copilot can find and read files on your PC, including synced OneDrive files. Check what it can reach under Account > Settings > File Search and File Read.
- Ask for help with Windows itself. Copilot can help you change Windows settings.
Shortcuts and settings
- Change what the shortcut opens (full app or quick view): Account > Settings > Copilot Keyboard Shortcuts in the Copilot app.
- Remap the Copilot key: Settings > Personalization > Text input > Customize Copilot key on keyboard.
- Pen button: on supported pens, Settings > Bluetooth & Devices > Pen & Windows Ink, then choose Same as Copilot key.
- “Hey, Copilot”: an opt-in wake word for starting a voice chat hands-free.

Example
The problem: a printer error pops up in a dialog you don’t understand.
You do: press the Copilot key, select + > Take a Screenshot, box the error, and ask “What does this mean and how do I fix it?”
A good result: a plain explanation and three or four steps, starting with the simplest. If a step involves changing system settings or installing something, check it against the printer maker’s support page first.
Mistakes to avoid
- Screenshotting private information. Crop out bank details, passwords and other people’s messages.
- Giving file access you don’t want. Review File Search and File Read if you keep sensitive files on your PC.
- Following risky fixes blindly. Don’t run commands or registry edits you don’t understand.
Good to know
