Your Windows 10 device may come with various Bluetooth versions. Depending on the version supported by your hardware, you may or may not have some of the Bluetooth features. For example, Bluetooth 4.0 adds Bluetooth Smart / Bluetooth Low Energy standard in addition to the Classic Bluetooth specification. It is a significant improvement in prolonging battery life of devices. Here is how to find which Bluetooth version your PC supports.
Bluetooth hardware can be embedded in your device's motherboard or it can be installed as an internal module inside the device. Bluetooth transmitters exist as an external device which can be connected to a USB port.
