How do I install a Bluetooth mouse with Boot Camp (Win10)? I'm trying to add a Bluetooth mouse to my Apple Macbook using Win10 on a BootCamp partition.  

--I purchased the Logitech M557 Bluetooth mouse as it seemed to have a great record for robust installation.
--Mouse works great on my MacBook laptop with MacOS.
--Mouse works great on my HP desktop machine loaded with Windows 10.

I can NOT get the bluetooth system to successfully mate with the same mouse with Bootcamp / Windows 10 on the very same Macbook laptop.  I suspect that I need custom Windows bluetooth drivers for Bootcamp (which I presume should come from the Apple BootCamp folks...)

Via windows device manager, I've removed, added, updated drivers numerous times, all to no avail.  Now, the add bluetooth system sees the mouse, attempts to add it, but fails consistently at: 

Bluetooth Mouse M557. Try connecting your device again.  

I have no idea what is generating that code, but no matter what I try I get no where.  

Anybody been here before?  Are there special Bluetooth drivers for Bootcamp / Windows?

Try to update your Bluetooth drivers through Intel's website. They do have drivers that you can download.
