Yes, you can have both. A Windows AI PC keeps privacy and productivity in balance when you set diagnostics to required only, review app permissions regularly, use on-device speech recognition and limit activity history syncing. Then tune Copilot, search indexing and hardware acceleration so the neural processing unit (NPU) handles more AI work locally. Here is how we would set it up.
Key privacy settings to adjust:
- Set diagnostics to "Required" only (not optional)
- Review app permissions regularly
- Enable on-device speech recognition (disable cloud)
- Limit activity history syncing across devices
Productivity optimisations:
- Customise Windows Copilot for task assistance
- Use local AI processing when possible
- Index only necessary folders for smart search
- Enable hardware acceleration for AI tasks
Bottom line: On-device AI processing (using your PC's NPU) handles sensitive tasks locally without sending data to the cloud, while optional cloud features remain under your control.
Windows AI PCs have changed the role of the personal computer. Instead of an add-on or accessibility feature, AI now sits inside the operating system and the hardware itself. Windows AI PCs use an NPU alongside the central processing unit (CPU) and graphics processing unit (GPU) to make AI processing a core part of how Microsoft® Windows 11 works.
Many people notice the difference in everyday work. Summarising files, getting a quick overview of a document and finding a misplaced file can take seconds. Because on-device AI processes information locally instead of storing it in the cloud, a Windows AI PC can also suit people whose work calls for tighter security.
That matters for hybrid workers, students, freelancers and small business owners across Australia, who often keep client files, banking details and personal documents on the same machine. The good news is that you don't have to choose. With the right settings, a Windows AI PC works with you to balance productivity and efficiency without requiring you to share extensive personal data.
Understanding Windows AI PC Privacy and Data Usage
Before we look at how to optimise your Windows AI PC for confidentiality, it helps to understand how these machines work. AI processing depends on input such as audio, images and text, so it's natural to wonder whether large amounts of your data are being collected. On-device AI processing doesn't store data in cloud storage, and it doesn't create its own files. Instead, it reads through existing files, processes them on the NPU and delivers the output in real time.
Diagnostics and feedback
A common type of data used by a Windows AI laptop is diagnostic and feedback information. Microsoft uses it to help improve system reliability and performance, and it can help AI features run faster and more accurately.
What diagnostic data includes:
- System performance metrics
- Feature usage patterns
- Error reports and crash data
- Hardware compatibility information
AI processing model design
Most Windows AI PCs use a hybrid processing model. On-device AI handles real-time tasks that call for privacy and speed, while complex requests may use cloud processing.
On-device processing (NPU):
- Speech recognition
- Background blur in video calls
- Real-time translation
- Local file analysis
Cloud processing (optional):
- Complex image generation
- Advanced content creation
- Web-connected queries
This approach separates the data Windows needs to function from optional telemetry, which gives you more say over what is shared.
Essential Privacy Settings to Configure
Windows 11 includes built-in privacy controls, and they are easy to reach. You can adjust each one to suit how you work. Menu names and paths can vary slightly between Windows 11 versions, so use the paths below as a guide.
Telemetry and diagnostics
Every operating system collects some data for diagnostics and improvement. This setting on a Windows AI PC controls how much data Windows collects and separates required data from optional data.
Path: Settings → Privacy & Security → Diagnostics & Feedback
Recommendation: Leave required diagnostics enabled and turn off optional data unless you're troubleshooting a problem. This keeps your system reliable without unnecessary sharing.
What this controls:
- System performance data sent to Microsoft
- Feature usage statistics
- Error reporting frequency
- Improvement program participation
App permissions
Some apps that use AI features may ask for access to hardware such as your microphone, camera, location or files. You decide which apps get access, and when.
Path: Settings → Privacy & Security → App Permissions
Recommendation: Only grant access to apps with a justified need. For example, if a speech-improvement app needs your microphone, you can allow it. That same app has no business requesting your contacts or other unrelated data.
Permissions to review:
- Camera (video calls, scanning)
- Microphone (voice commands, transcription)
- Location (maps, weather)
- Files and folders (document processing)
- Notifications
Windows Copilot data controls
Windows Copilot is an AI assistant that many people use to boost their productivity. It doesn't need broad access to all of your information to be useful.
Path: Settings → Privacy & Security → Copilot
Recommendation: Allow basic system context while avoiding long-term content history. Think of Copilot as a helper, not a logbook.
Best practices:
- Enable task-focused assistance
- Disable conversation history if you work with sensitive data
- Limit access to personal files unless necessary
- Review data retention settings
Activity history
Activity history helps you keep track of what you do across devices. It falls under optional data collection, so you can turn it off.
Path: Settings → Privacy & Security → Activity History
Recommendation: Keep local history enabled for convenience and disable cloud syncing if you don't need cross-device tracking.
What this affects:
- Timeline feature in Task View
- Cross-device app continuity
- Microsoft account activity tracking
- Personalised recommendations
Speech recognition
Voice features are one of the clearest examples of AI running locally on your NPU.
Path: Settings → Privacy & Security → Speech
Recommendation: Enable on-device speech recognition and disable online speech services if privacy is a priority.
Key distinction:
- On-device: Processes voice commands locally on your PC's NPU
- Online: Sends audio to Microsoft servers for processing (more accurate but less private)
Optimising AI Features for Productivity
Once you know which privacy settings suit your confidentiality needs, it becomes much easier to trust AI-powered apps on your PC.
Windows Copilot
Windows Copilot supports productivity and accessibility by closing the gap between a question and an answer. When configured well, it provides AI summaries of text, document suggestions and overview assistance. It can also replace digging through menus and documentation. Our guide to Copilot+ PCs explains how a dedicated NPU unlocks more advanced Microsoft Copilot™ features.
Best practices:
- Customise Copilot to focus on task help rather than personal content
- Don't fill Copilot chats with personal or sensitive information
- Use Copilot for system commands and general assistance
- Review data sharing settings regularly
