If you want to get driver v126.96.36.19993 working on Windows 10, you can perform the following steps:
Extract the .zip file (from original post) and navigate to: \Win7Vista_64_152258\Graphics\
Open the kit51428.inf file and search (or scroll to line 69) for: IntelGfx.NTamd64.6.2
You'll take what's there, and add 2 lines, so it looks like this, and save the file.
; no install on Win8
%iILKGM0% = iILKM0, PCI\VEN_8086&DEV_0046
%iILKG0% = iILKD0, PCI\VEN_8086&DEV_0042
Now, since you modified the file, the signature is invalid. We'll need to boot up without signature enforcement.
In the Start Menu, search "Change advanced startup options" --> "Restart Now".
When your computer restarts, Press F7 on your keyboard to select Disable driver signature enforcement
When you're back in windows, you can update the graphics driver by pointing to the kit51428.inf file you modified in step 2
Here are the "FF03" and "FF10" versions of the 188.8.131.5259 WHQL driver pack - nearly the same as FF00 version but with minor differences (these are rare finds 🙂).
FF03 with Nahimic integration
FF10 with Creative integration
Edit 6/20: I have discovered that the 8459 "FF03" driver package includes the 40 byte rtkhdaud.dat file dated 6/12/2018 stored in the Config folder, which may cause certain ASUS laptops & motherboards to not show or prevent the Realtek HD Audio Manager control panel program from running when installed onto the Windows\System32\Drivers folder. However that same rtkhdaud.dat configuration file may actually help or make the Realtek HD Audio Manager control panel program work on Sony brand desktop/laptop computers where normally the Realtek audio control panel never worked on Realtek audio chipsets found on Sony OEM machines without this new rtkhdaud.dat file.

for ASUS users - remove/delete the rtkhdaud.dat file from the Config folder before installing the 8459 FF03 driver.
