Those are BT things, and MS BT stack is just crap. Either use the Toshiba, or Widcomm, or Bluesoleil stack, or just ignore the entries unless you miss a BT functionality that you actually use.
Try the toshiba one first, if it works it's the least problematic and lighter one. But sometimes it lacks the driver for integrated bt devices, so given the parent device is not recognized, nothing else is. External BT dongles, usually, will work w/o a glitch.
Look, the threadtitle is incorrect, the OP asks for updates but actually asks for drivers.... neverending thread..
Which is true. Driver and stack are 2 different things Your device is recognized correctly by the MS driver. But the child functionalities are not managed correctly by the (MS) stack. MS tried for ages to kill the BT, given it's an European tech out of their control.
I only brought up the drivers because someone asked for an explanation. I'm updating because apparently there are occasionally drivers rolled into the updates or at least that's what windows always implies when automatic driver search fails.
The set allows to update the working system, and also to integrate updates into the distribution.
