Some of the features in Windows operating system is available only if you are running a specific or later version of Bluetooth. For instance, the Nearby Share (a feature to share files between two Windows 10 computers) requires Bluetooth 4.0 or later versions. Bluetooth 4.0 adds Bluetooth Smart / Bluetooth Low Energy standard in addition to the Classic Bluetooth specification, so it is a significant improvement in prolonging battery life of devices. The batteries in Bluetooth low energy devices will last several times longer than their classic Bluetooth counterparts.
Bluetooth version number is usually mentioned in PC’s manual or product information page on your manufacturer’s website. But if your laptop is few years old, you likely have lost the manual and might not be able to find its information on the web as well.
