Locate the file, than go to Device Manager, and select (Double Click) the device you want to update the drivers for. Go to the 'Driver' tab and select 'Update Drivers'. Then select 'Browse my computer for driver software', and navigate to the folder with the sys file and hit next. If the driver in the folder is newer that the current installed one, it will update it and may tell you to reboot. If it is older, it will skip it and inform you as such. Alternatively, on the 'Browse for driver software' window instead of selecting 'Browse' you can select the lower option 'Let me pick for a list' and the select 'Have Disk'. Navigate to the .INF File and click 'OK', and in the window it will show you all the applicable drivers for your device in that folder. Then just select the one you want. Hope this helps
***Edit*** Misspoke typing folder instead of .INF File
It should be in there if you have the right driver pack. When updating drivers you don't to find the exact file, just point to the Folder it is in. I need a few more pieces of information to help you further. First, what is the model computer or motherboard and CPU (for custom builds)? Second, I am assuming by "Generic" you mean Intel's base drivers, if so did you get them from the Intel Downloads Center? Third, is your OS a 32 or 64-bit build? Lastly, what is the driver you have now, and who is it from?

Well, the New driver gave some of my games a lot of FPS reduction, with the 2013 Driver that game would run at 100fps and more, the new driver killed them to 40fps.
So I'm interested to see what happens with the 2014 Driver, but there's no ighdl64 in that one, there's a kit64ics, is that the same as the ighdl?
