PC users who have a Apple Wireless Keyboard can connect the wireless input device to their computer via Bluetooth connection. As with all Bluetooth devices, the Apple Wireless Keyboard is given a name when connected to the computer. If the given name is a series of letters or numbers, or words that don’t make it obvious that the connected device is a keyboard, you can change the name to something suitable. The name is changed in the Properties options for the device. Warnings Writer Bio
