Windows WiFI Wireless Adhoc connections by default

On Episode 81 from Security Now... I Learned about "FreePublicWiFi" entry that gets propagated (I've actually seen this before) / Wireless Ad hoc connections by default

Windows XP's "zero configuration WiFi" system defaults to the almost-never-useful and always-potentially-dangerous mode of connecting to non access point WiFi devices in so-called "Ad Hoc" mode. This has potentially serious security consequences. This is an insecure default which SHOULD be changed on every XP-based WiFi machine.

This episode also has some great info about Hard Drive failures...
