Hi Nitish, I am John J.D., a fellow Microsoft user like you.
I understand your concern, and I'm here to help. Firstly, it's worth noting that after a recent upgrade or fresh installation, Windows often performs various background tasks that can temporarily consume more resources. You mentioned that your system is only 2 days old, which suggests this could be a factor.
Here are a few steps you can take to address this issue:
> Check for Updates > Make sure your system is fully updated. Go to Windows Update and ensure all updates, including drivers for graphics, sound, and network, are installed. Pending updates can sometimes cause high resource usage.
> Check Properties of Secure System > Right-click on the Secure System process in the Task Manager and click on Properties. If it shows ntoskrnl, this is part of the normal operation, but still worth monitoring.
Also, try running DISM and SFC command to automatically repair and restore any potential system file issues. Steps 2 to 5 can be found here: https://support.microsoft.com/windows/using-sys...
After running DISM and SFC command, restart your PC and check if issue persists.
