Microsoft introduces new privacy controls in Windows 11, allowing users to reduce data sharing, personalise settings, and limit activity tracking without compromising core functionality, marking a shift towards greater user privacy.
Windows 11 is designed to be useful out of the box, but several of its convenience features depend on data collection and personalisation. According to Microsoft’s own support pages, the system can gather diagnostic information, shape recommendations, serve more relevant advertising and tailor search results based on how a device is used. For people who prefer a quieter setup, those options can be reduced without breaking core functions. The aim is not to strip Windows back to bare essentials, but to cut the number of signals the operating system and its apps can use to profile activity.
The first place to look is Diagnostic and feedback settings. Microsoft says Windows always collects a minimum set of diagnostic data needed for security, updates and basic device information, but users can still switch off optional diagnostics, including additional usage signals, and disable tailored experiences. Those tailored experiences use diagnostic data to deliver tips, suggestions, adverts and recommendations. In practice, turning these options off reduces the amount of behavioural detail Microsoft can use to shape the interface, while leaving the machine fully functional.
The same logic applies to Windows’ advertising ID and recommendation features. Microsoft explains that the Advertising ID lets apps present more relevant adverts, and that it can be reset or turned off from Privacy settings. Its support guidance also notes that Windows Search and Start can be influenced by app-launch activity and cloud-linked content, with separate controls for personalisation and account-based search suggestions. Disabling those options will not remove adverts altogether, but it does limit how closely they are matched to prior behaviour.
Another important area is activity tracking. Windows 11 can record usage data such as recently opened apps, files and browser activity in Edge, then use that history to support continuity across devices. Microsoft has also removed or altered some of the older Activity History controls in newer Windows 11 builds, which has led to confusion for users trying to find the setting. Where the option is available, switching it off and clearing stored history reduces the amount of longitudinal data Windows can retain about how a PC is used.
App permissions deserve the closest inspection because they can expose more sensitive data than system-level telemetry. Microsoft’s guidance says Windows apps may request access to location, camera, microphone, contacts and other device features, and that users should decide whether each permission is genuinely necessary. That advice matters because many utility apps do not need broad access to work properly. Reviewing those permissions one category at a time is slower than changing a single switch, but it is one of the most effective ways to reduce unnecessary exposure.
Speech input is another setting worth checking. Microsoft says online speech recognition improves dictation accuracy by sending audio to the cloud, which means voice data may leave the device when the feature is enabled. For users who rarely rely on dictation, turning it off is a straightforward trade-off: slightly less accuracy in exchange for less cloud processing of spoken input. Taken together, these changes do not make Windows 11 anonymous, but they do narrow the amount of information used to personalise ads, suggestions and system behaviour.
