Lenovo Vantage App was causing Windows Laptop Slowdowns

I’ve been dealing with persistent slowdowns on my high-spec Lenovo Yoga Aura, even though there’s no obvious reason for the performance drop. Today I decided to start from scratch and reinstalled the operating system to rule out any software issues. After setting everything up again, the system was running smoothly—until I reinstalled Lenovo Vantage, which is Lenovo’s built-in utility for managing hardware settings, system updates, power modes, and performance optimization.
As soon as Vantage was installed, the performance degraded significantly, to the point where the machine became extremely sluggish. After uninstalling it, the system immediately returned to normal with no noticeable lag. This makes me question whether Lenovo Vantage itself could be responsible for the slowdown, even though it’s designed to control and optimize the system.
At this point, the system runs well without it, but still how can I manage device settings without the app?
