On Windows 11 (and on Windows 10), Bluetooth is a short-range networking technology that allows you to connect compatible devices (such as headphones, speakers, mice, and keyboards) to your computer wirelessly.
Although, for the most part, you never have to worry about the version of the Bluetooth adapter you use. Sometimes, to use a specific feature, you must have a particular version that includes a specific technology. For instance, your computer must have Bluetooth 4.0 with Low Energy (LE) support if you want to use the Nearby sharing feature to send files and links to nearby devices.
If you need to know the wireless adapter version, you can quickly find out by checking the company’s support website or the system information.
In this guide, you’ll learn the steps to quickly tell the Bluetooth adapter version installed on Windows 11.
