What is the Registry location that Windows Vista stores the wireless key ?
Windows Vista doesn’t store the wireless keys in Registry anymore. Instead, the keys are stored in the file system – under c:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces\[Interface Guid]. The [Interface Guid] is a unique GUID value the represents your wireless network card. The keys are stored and well-encrypted inside the .xml files that you can find in the above path.
