I received my SurfacePro3 (i7/512) and set it up as a brand new computer (did not transfer any files). It is replacing a laptop which ran either Windows 7 or 8.1. I used the laptop to teach computer classes for seniors at the University Extension center. When I setup the SP3 here at home, it knew about a wifi network that does not have it's SSID advertised and the password to access that network. When I went to the University, it knew the WiFi settings and password to get on their network. I'm sure this is a windows issue more than an SP3, but I was not aware I was storing network IDs and passwords in the cloud. I need to know how that is happening so that I do not continue to have that information available. I did re-use my Microsoft account and am thinking that is the culprit, but do not see any options to not store that info and share among all computers. And help/directions to the proper forum on instructions would be appreciated.
