After Boot Camp Windows Installation Network Problems

hello guys!

After a lot of hard work I install the windows on my Mac

But the as I reached the Windows desktop I saw errors again

I am not able to access the wifi because there is not driver installed for and cannot use the right click

I install the Windows service software which is I think downloaded from the apple website but this major error

I have installed Windows 8.1 pro

PLEASE TRY TO SOLVE MY PROBLEM ASAP

I THANK YOU FOR SOLVING MY PROBLEM IN ADVANCE
