Recently, a rumor has been swirling on social media platforms, claiming that Windows 11 has introduced a new background service that 'hinders system performance', stirring up apprehensions among users regarding both system speed and privacy. Microsoft's technical expert, Scott Hanselman, stepped forward to publicly refute these claims, providing a detailed explanation of the service's actual intent. Following the Windows 11 update, it was noted that certain services, including Appxsvc, were configured to launch automatically. These services are tasked with managing the deployment, installation, and updates of applications from the Microsoft Store. However, this adjustment has sparked concerns among users over potential resource consumption. Moreover, other factors such as glitches in the Task Manager, OneDrive cloud synchronization processes, and the system's built-in visual effects have also been identified as potential culprits contributing to the perceived system slowdown. In response, Microsoft has offered optimization advice and pledged ongoing efforts to enhance system performance.
