I'm trying to migrate the settings of my old machine (Win XP Professional) to the new one (Win 7 Professional) and I would like to keep my saved passwords for various wireless networks. How can I export them from XP and import in Win7?

A few things that are mentioned a lot in chat groups but don't work:

• netsh can export/import wlan profiles on Vista/Win7, but not on XP;
• the Wireless Network Setup Wizard can only export settings for networks created by me;
• the best method I found was via http://www.nirsoft.net/utils/wireless_wep_key_faq.html which can list hex keys, but cannot load them nor save them in a useful format; I would rather not copy them one-by-one by hand.
