I had the same problem after installing XP/SP3
, but let's fix it the easy way.
1) Do a backup of SystemState (or everything).
2) Uninstall the D-Link device. Windows will ignore it until you reboot... so don't reboot.
2) Install the latest driver. It will try to get you to reconfigure, but who can find their WEP info when they need it, so just exit.
3) Restore SystemState to restore your configuration.
Everything comes back as it was. There is a useless desktop icon to delete, and the system tray shows the power meter, but the dialog box is GONE!
AirGFCG.exe is a non-essential component launched at startup from the registry, so the entry can be deleted altogether.
