Well, really, I doubt that the drivers that Microsoft installs right now "work as intended." Microsoft isn't that cruel. Seriously, the drivers referenced here do solve many problems and will be replaced whenever Microsoft finally provides an update.
Strange...I ran the latest driver update on the Intel website, but my drivers seem to have reverted to 220.127.116.1100 with release date 10/9/2015.
I never checked the drivers after the firmware update. Wonder if it's a bug with the date code in the new Intel drivers or if the firmware update really did revert me back to the previous MS release Intel drivers...?
