    KB4091666 update has been re-released as revision V2 to now include Ivy Bridge & Sandy Bridge processors

    Important note: KB4091666 V2 can only be installed under Win10 v1507 LTSB edition and will not install under other editions as Microsoft had already ended support for all other editions of Win10 v1507 in mid-2017 except for v1507 Enterprise LTSB.
