Adjunct to How to get a stored WLAN “password” from Windows 7?How to get a stored WLAN “password” from Windows 7?, how do I back up and restore (in case of reinstalling the wlan adapter driver) or transfer (in case of switching wlan adapters or laptops) WLAN profiles?
WirelessKeyView can export the profile data unto a text file, but not import it back. In my case, I have 50 "saved passwords" -- too much to copy and paste.
