Why Windows Privacy Matters

Windows collects various types of data by default, including diagnostic information, location data, advertising preferences, and activity history. While some collection helps improve Windows, you have the right to control what is shared.

This tutorial walks through the most important privacy settings in Windows 10 and 11 so you can make informed decisions about your data.

Disabling the Advertising ID

Windows assigns a unique advertising ID to your account, used by apps to serve targeted ads.

1
Open Settings (Win + I) and go to Privacy & security
2
Click "General" under Windows permissions
3
Turn off "Let apps show me personalized ads by using my advertising ID"

While here, also consider disabling:

  • "Let websites show me locally relevant content by accessing my language list"
  • "Let Windows improve Start and search results by tracking app launches"
  • "Show me suggested content in the Settings app"

Location and Camera Controls

Location Services

Navigate to Privacy & security > Location:

  • Location services: Turn off entirely, or leave on and control per-app
  • Location history: Click "Clear" to remove stored location data
  • Review the app list and disable location for apps that do not need it

Camera and Microphone

Navigate to Privacy & security > Camera (and separately, Microphone):

  • Review which apps have camera and microphone access
  • Disable access for apps that should not need it
  • Keep "Let desktop apps access your camera" enabled only if you use video calling apps
💡
Camera indicator light

Most laptops have a physical LED that lights up when the camera is active. If it activates unexpectedly, investigate which app is using it.

Diagnostic Data Controls

Navigate to Privacy & security > Diagnostics & feedback:

Required diagnostic data Minimal data needed for Windows to function (cannot be disabled)
Optional diagnostic data Additional usage and browsing data - disable this for better privacy
Tailored experiences Uses diagnostic data for personalized tips and recommendations - disable

Also click "Delete diagnostic data" to remove what has already been collected.

Activity History

Navigate to Privacy & security > Activity history:

  • Uncheck "Store my activity history on this device"
  • Click "Clear activity history" to delete existing records

Activity history tracks which apps and files you use, which feeds the Timeline feature and cross-device sync.

App Permissions Overview

Under Privacy & security, scroll down to the "App permissions" section. Review each category:

  • Contacts, Calendar, Email: Only allow apps that genuinely need access
  • Notifications: Controls which apps can read your notifications
  • Account info: Controls access to your name, picture, and account details
  • Documents, Pictures, File system: Restrict broad file system access
⚠️
Do not disable everything blindly

Some apps need certain permissions to function. For example, a video call app needs camera and microphone access. Review each setting based on whether the app genuinely needs it.

Summary

In this tutorial, you learned:

  • How to disable the advertising ID for less targeted ads
  • Managing location, camera, and microphone permissions
  • Reducing diagnostic data collection
  • Clearing activity history
  • Reviewing and restricting app permissions

Your privacy is now under your control!

Revisit these settings after major Windows updates, as Microsoft sometimes resets preferences.
