Why does this matter? Because the BR100 represents a pre-“in-box driver” era when Sony, like Apple, controlled the stack tightly. When Windows 10’s driver model changed, Sony simply didn’t care. No open-source fallback. No final legacy driver. Just silence.

Here’s an interesting, slightly investigative piece on the Sony UWA-BR100 driver for Windows 10 : The Ghost Driver: Chasing Sony’s UWA-BR100 on Windows 10 Why does this matter
Some hobbyists have succeeded — but only by forcing an old Lenovo Bluetooth driver, editing registry keys, and sacrificing a weekend. The result?
