Microsoft is enhancing Windows 11 performance by collecting comprehensive data on performance-related issues through feedback from users testing preview builds. A new feature in the Dev channel preview build encourages testers to report sluggish performance, allowing the Feedback Hub to automatically collect logs to identify root causes. Users have reported challenges such as sluggish search functionality and inconsistencies with File Explorer, particularly on older hardware. Data collection is limited to preview build users, with logs stored on testers' devices and accessible to Microsoft only if feedback is voluntarily submitted, ensuring user privacy.
