Windows 11 collects your activity history, including the apps, files you open, and websites you visit, to personalize experiences across devices. While convenient, this data is stored locally and potentially synced to Microsoft’s servers if you’re signed in with a Microsoft account.
Disabling activity history prevents this logging and syncing. You can turn it off by visiting Settings > Privacy & security > Activity history. Unchecking both options ensures Windows no longer stores or shares this information.

Microsoft assigns a unique advertising ID to each user, which allows apps and services to track behavior and deliver targeted ads. This means your usage patterns influence the ads you see, even in third-party apps.
Although Microsoft says the data is anonymized, it still builds a profile around your habits. To turn off ad tracking, go to Settings > Privacy & Security> General and toggle off “Let apps show me personalized ads.” This helps reduce how much your behavior influences ad targeting.

Windows 11 tracks your device location to provide services like weather updates or finding your device. While helpful, this data can be stored and shared with Microsoft and app developers. If you rarely use location-based services, turning this off is safer.
Head to Settings > Privacy & security > Location and toggle off “Location services.” You can also clear your location history from the same menu. This limits background tracking and prevents apps from silently accessing your location.

When you sign in with a Microsoft account, Windows 11 automatically syncs your settings across devices, including passwords, browser history, and themes. While this is convenient, sensitive data is stored in the cloud.
To reduce risk, go to Settings > Accounts > Windows backup and turn off options like “Remember my apps” and “Remember my preferences.” This stops Windows from syncing personal configurations to Microsoft’s servers, giving you more control over where your information is stored.

The voice typing feature in Windows 11 lets you dictate text, but enabling it means your voice data is transmitted to Microsoft’s servers for processing. While the company claims it improves speech recognition, your spoken input may be stored temporarily.
To turn this off, go to Settings > Privacy & security > Inking & typing personalization and turn off “Personal inking and typing dictionary.” This prevents Windows from collecting voice data in dictation or other speech-based features.

“Find my device” in Windows 11 helps you locate your lost computer by periodically sending its location to Microsoft. While helpful for theft recovery, it also means your device’s whereabouts are stored externally.
Turning off this feature can improve privacy if you don’t travel with your device or use it at home. Navigate to Settings > Privacy & security > Find my device and toggle it off. This ensures your device doesn’t automatically report its location to Microsoft’s servers.

Windows Defender SmartScreen checks the apps and websites you access against Microsoft’s database to flag threats. While it helps block harmful content, it also reports your web activity and app launches to Microsoft.
Consider turning it off if you’re confident in your browsing habits and use a secure browser. Navigate to Settings > Privacy & security > Windows Security > App & browser control. You can adjust SmartScreen settings to reduce constant monitoring without entirely turning off security features.

Windows 11 includes “Suggested content in Settings,” which promotes apps, tips, and updates based on your PC use. These suggestions are not stored locally and rely on behavioral tracking.
To turn them off, go to Settings > Privacy & security > General and disable “Show me suggested content in the Settings app.” This stops Windows from sending usage data to recommend features or third-party software, giving you a cleaner experience without tailored ads or nudges.
Windows regularly asks for user feedback and may collect additional information during those prompts, especially when feedback frequency is set to “Automatically.” To reduce unnecessary data uploads, change this setting.
Go to Settings > Privacy & security > Diagnostics & feedback > Feedback frequency and set it to “Never.” This stops Windows from collecting user experience data through spontaneous feedback requests and ensures your device isn’t constantly monitoring interactions for input collection purposes.

Many installed apps have automatic permissions to access your camera, microphone, contacts, and more. Windows 11 gives them this access by default unless you manually revoke it. This can lead to the unintentional sharing of personal data.
To review and manage these settings, visit Settings > Privacy & security > App permissions. Click into categories like Camera or Microphone and toggle off access for apps that don’t need it. This ensures only essential apps can access your private information.

Clipboard history allows Windows 11 to remember what you copy, and with sync enabled, it shares that content across all your devices. While convenient, sensitive data like copied passwords or messages could be uploaded to Microsoft’s cloud.
You can turn this off by going to Settings > System > Clipboard and turning off both “Clipboard history” and “Sync across your devices.” Doing this keeps your clipboard usage local, reducing the risk of private data being stored online.

Search highlights in the Windows 11 search bar show trending content, holidays, and suggested searches based on your location and usage. These are pulled from the internet and can personalize results using your Microsoft account.
If you’d prefer a private local search, go to Settings > Privacy & security > Search settings and disable “Show search highlights.” This stops Windows from fetching online content for your search experience, keeping your queries confined to local files and apps.

Even if you turn off most data collection settings, Windows 11 sends essential telemetry data to Microsoft. This includes system performance, error reports, and basic app usage.
While the “Required” level can’t be turned off entirely in non-enterprise editions, you can limit exposure by turning off all optional feedback and in-app data sharing. Go to Settings > Privacy & security > Diagnostics & input and turn off all toggles that are not marked as mandatory. This helps narrow what gets sent out.
While telemetry quietly sidesteps user controls, Microsoft’s new AI agent is making even bigger moves. See how it’s reshaping Windows 11.

Wi-Fi Sense was designed to make sharing access easier among trusted contacts, but it also means your device may automatically connect to known networks and share credentials.
Wi-Fi Sense was discontinued in Windows 10 and does not exist in Windows 11. However, users can still review their saved Wi-Fi networks to improve security.
To ensure Wi-Fi data isn’t shared, go to Settings > Network & internet > Wi-Fi > Manage known networks and remove unused ones. Turning off automatic connections improves privacy and control.
As Windows 11 gets a quantum-safe security boost, features like Wi-Fi Sense raise questions about how much your network shares behind the scenes.
