Intel Graphics drivers, and brightness adjustment are not working [HELP]

[irsyadhhs]

i installed the w10 first build and all drivers worked properly.

but, after the jan update, intel and nvidia driver won't be installed. it says in windows update : error 0x80070003

my laptop is Asus A451LN intel i5 with geforce 840M

so i download the driver from asus site, and run the driver in compability mode. the nvidia is working as expected, but the intel won't. it's installed, but after restarting, it's gone.

and i can't adjust the screen brightness. please, i need help. the only thing i want is the brightness adjustment. i'm not a geek gamers or something else.

i'm fine with all the buggies in w10. BUT PLEASE, HELP ME FIND OUT THE SOLUTION FOR THIS BRIGHTNESS ADJUSTMENT(

Have you tried downloading the driver from Intel's site?

I am guessing the onboard version is HD4400?

Here's the download link: https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24596&lang=eng&ProdId=3719
