Profiles that connect automatically are a security risk. Most OSes are aware of this now and have supposedly fixed the problem.
I learned about the issue of automatically connecting wifi devices from that very video! My company prefers ease-of-use than security though (seems to be a common complaint from the security-minded folks). It'll take an incident happening before a policy to "disable automatically connecting to AP's" is implemented.

"does the Windows network manager reference these entries when connecting to SSID's? "..........yes
"Does it cross-check the MAC addresses found in these entries when connecting?"...........yes.
My guess is that why a device would keep connecting to a specific AP even though it has a lower signal strength than another AP with the same ESSID is because its MAC is in the Preferred Network List.....
My thoughts exactly, but I wasn't for sure because of...

...this. I was also under the impression that wifi devices would switch automatically once some threshold is met, but I don't know what this threshold is. Losing signal completely...or once it gets to <10% signal strength...? I was curious about this also.
For my purpose, these laptops are stationary in their respective offices for the most part, so I don't have to worry about them roaming very often (would love a wireless controller to cover this just in case, but need $$ for that haha). We had one AP fail and all of the laptops switched over to this other AP with a lower signal strength. I have the new AP in place, but had laptops still connecting to the old WAP. This was resolved by blowing away the wireless profile and recreating a new one when connecting to the ESSID with the stronger signal.
Thanks for the input, WCNA. Let us know when those securitytube t-shirts are out!
