Passwords are not saved in reports (Don't ask why!).
SIW can only be used to recover the passwords for the current logged-on user on your local computer.
SIW only works if you chose the remember your password in one of the above programs.
You cannot use this utility for grabbing the passwords of other users.
Notice for Windows XP users: If your network has WPA encryption then the recovered password would be in 64 HEX digits BUT you can use these digits to connect to internet same as a password. This is not a bug. Windows XP can’t convert WPA back the original password. Windows Vista, Windows 7 and Windows 8 don’t have this issue. WEP passwords in Windows XP are recovered without a problem.
