Slow Performance and System Lag in Windows 11

Slow performance and system lag on my Windows 11 computer, which significantly affects my productivity and overall user experience. Despite trying various troubleshooting steps like closing background programs and updating drivers, the issue persists, and my system still runs sluggishly, especially when opening multiple applications or running demanding tasks.

    In Settings > System > Power & Battery, set the power mode to “Best Performance,” and disable unnecessary startup items in Task Manager.
