I've just connected a Bluetooth mobile phone to my Vista laptop.
The modem has been beautifully named: "Standard Modem over Bluetooth link #3".
What do I do, short of editing the registry, to rename the device?
In registry, you can do this, but I don't recommending do this, because this change has many bad consequences.
HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Enum
And here is list of devices in categories. Each device has DeviceInstanceID.
Name is under DriverDesc or FriendlyName and you can change.
