Recently, Windows 11's performance has come under fire from users, with a particular background service, 'Windows Health and Optimized Experiences,' grabbing the spotlight. Earlier, whispers circulated that this service keeps a close eye on processor details, temperature readings, and battery status, relaying this data to Microsoft every quarter of an hour. However, after delving into the core of the service's whesvc, reverse engineer Xusheng Li discovered that, despite the service's broad system access, the scripts in place are mainly geared towards performance diagnostics. Notably, there was no evidence of automatic user data uploads or screen surveillance.
