Review Windows 11 25H2 privacy settings after an upgrade. Reduce unnecessary data sharing without breaking diagnostics, updates, or essential Windows features.
Audit **Windows 11 25H2** privacy permissions after a feature update, restrict unnecessary access, and review diagnostic data settings. These changes reduce optional data sharing but do not make Windows anonymous or protect against malware.
Open **Settings** and check your Windows edition, version, and OS build. Review Windows Update history so you can distinguish changes caused by the feature update from existing configuration. Privacy settings do not replace account security or endpoint protection.
Open **Privacy & security** and inspect the general privacy options. Disable advertising ID, personalized experiences based on diagnostic data, and suggested content where available. Some recommendations and personalized experiences will become less relevant.
Open **Diagnostics & feedback**. Review optional diagnostic data, tailored experiences, and feedback frequency. Disable optional data sharing if you do not need the additional diagnostic features. Windows still collects required diagnostic data, and some diagnostic controls may be managed by an organization.
Inspect **Activity history**, search permissions, and recommendations in Settings. Turn off activity collection or history options you do not use, and clear stored activity history if desired. This does not erase browser histories, cloud account records, or information already sent to services.
Open the permission sections under **Privacy & security**. Review location, camera, microphone, contacts, calendar, and other available permissions. Disable access for apps that do not need it; apps relying on those permissions may lose corresponding features.
Review **Windows backup**, OneDrive settings, and Microsoft account synchronization. Disable synchronization or backup options you do not want, but retain recovery options for files and settings that matter. Local privacy changes do not automatically remove data already stored in the cloud.
Restart Windows if prompted, revisit the settings you changed, and confirm that Windows Update and Microsoft Defender remain enabled. Test search, location-dependent apps, camera, and microphone if you changed their permissions.
Check whether Windows is managed by an organization, whether your account has administrator rights, and whether the setting is supported by your edition. Do not bypass organizational policy on a managed device.
Open Settings > Privacy & security, select the relevant permission, and restore access for the app. Also check the app's own permission settings.
Review Start, Settings, and notification preferences separately. Disabling personalized diagnostic experiences does not remove every recommendation or system notification.
No. It reduces selected data collection and permissions but does not eliminate required diagnostics, account records, or network tracking.
Yes. These steps leave Windows Update and Microsoft Defender enabled.
No. Keep permissions needed for features you use, such as location navigation, voice calls, or camera meetings.
Open Settings > Privacy & security and restore the individual options you recorded before making changes. Re-enable any app permissions needed for normal operation. Restore desired cloud synchronization and backup settings separately. No system restore point is normally required for these reversible Settings changes.
