1] What causes Realtek Bluetooth radios compatibility issues?
Microsoft found that some driver versions for Bluetooth radios made by Realtek were causing compatibility issues. As such, the company advised Windows users to update to driver version 1.5.1012 or later to remove this safeguard hold. Any version of the driver, earlier than this installed on your PC would stop users from proceeding forward and successfully installing the update. REALTEK Bluetooth is a program developed by Realtek Semiconductor. When installed and set up, the driver adds a context menu handler to the Windows shell in order to provide quick access to the program. Besides this, it also defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. Read: How to check the Driver Version in Windows.
