Realtek shows only 4mb

I have installed realtek audio driver but I can't see drivers in control panel or in c drive I see realtek folder only having 4 mb. Btw I'm on windows 10 1809 , motherboard gigabyte h110m s2.
 
Hmm, does the sound chip show in Device Manager? Win+X > Device Manager > Sound controllers
 
I have done this all updates my driver's too and ya bte in c drive it has a realtek named folder having audio but nothing inside the audio folder
