How to fix lagging issue in my brand new acer predator helios neo 16s ai 2025 (RTX 5060)

Hey,
Can anyone explain or tell me the solution for little bit lag in my new acer predator helios neo 16s ai (RTX 5060).

Lag is in terms of whenever i open task manager it takes 4+ seconds to load and also

Whenever i click on wifi on bottom most right corner of task bar to open nevigation panel, it simply freez, for some time.

Also, whenever i lock my pc it takes time to show the lock screen like 4+ seconds to load the lock screen content.

This type of lag is measurable, i can feel it slownes of computer.

Condition of my laptop in above situation is in balanced mode, no heavy task running in background.

1. All driveres are uptodate,
2. all windows latest updates are installed,
3. all unwanted apps deleted,
4. even fast shutdown option is also disable.
5. All microsoft feedback options are disable (Inking typing, diagonstic feedback, general, security, search all feedback are disable)
6. Only acer sofwares are installed like (Acer sense, acer voice and quick panel)
7. Mcafee antivirus was uninstalled also when free trial expired.

Still this new laptop is lagging in simple task then waht to do ?
