I need to buy a standard Bluetooth dongle for my home-build desktop computer to solve a nasty bug relating to updating from Windows 7 to Windows 10. The upgrade tool FALSELY reports that there's an outdated Realtek Bluetooth driver installed (an absolute lie) and so refuses to allow the upgrade to continue. The Microsoft "solution" absolutely will never work on computers that do not already have a Bluetooth device based on a Realtek chip.
But I've searched exhaustively to find and buy such a Realtek-based dongle, but none of the 40 or more dongles specify which Bluetooth chip they use in their products! HOW DO I FIND ONE?
