No program is Running but 50% CPU usage

Hi,
On my Laptop no program is running and PC is in Idle Condition.
But CPU usage is still 50% percent which is making my fan to run continuously and also the busy doodle is coming up continuously with the pointer as well.Also my laptop heating up although PC is idle.
Also on my other user account on this PC there is no such problem of PC being used up to 50% without any program running. I have attached this screenshot which is showing my task manager output.As you can see no major program is running but the PC usage is still 48%.
Please help me out I'm worried.
Thanks in advance

Check Details tab and sort it by CPU usage.

It seems like Windows Driver Foundation service is the culprit here. Disabling that service is not recommended, so you have to find the problematic driver. Try updating your drivers, especially wifi driver.

but the if the problem is with my windows drivers then why I'm not encountering the same problem on other user name on same pc.
I'm encountering this problem on one of the two username here is a screenshot from my other brother's username on my laptop.

In that case, it might be triggered by some application, that you are using and he does not.
If it happens as soon as you start the PC, try to temporarily disable all your startup apps.
Start - Run - msconfig - Check Selective startup and Uncheck Load startup items.

This is task manager screenshot all application disabled.
i went to system config but it redirected me here
