Windows' Bluetooth stack is an absolute dumpster fire. They trashed the perfectly good BT stack from windows 7 and apparently had an unpaid intern write the replacement. My day job is building widgets that connect to a windows PC over Bluetooth. The situation is so bad that we're building a dedicated RF adapter so we can have a sane stack under our control. If your program is scanning for a particular device in the background, that device will never show up in the windows BT pairing menu. I can't even imagine how that happens. Many API calls do nothing or return garbage, many BT features are just not exposed at all, despite windows clearly having that data internally. W10 never even had BT audio sink. You could not play audio from a remote device to your PC. W7 had it and I think W11 finally got it a few years back. Linux has always had it. Windows' Bluetooth stack is no contest the worst available on the market. It's astonishing how poor quality Microsoft products are these days.
