Default surface updates

i have been checking my updates and i see that i have one system hardware update ( i believe a driver) but i dont know what it is as there is no info about it. i click on the support info link but that just sends me to a general windows page. how can i search for an update when i dont know what it is. usually with the other updates there is a kb number that you search for and get info. as this is not a win software update there is no number.

i dont want to dl something i dont know what its for.

anyone got any clues.?
