Since upgrading my ASUS Zenbook to Win 10 three weeks ago, I've been having trouble with bluetooth. Basically, every time I turn off the computer (log off), when I reboot I get just one driver showing up and a "code 43" error (under device manager) and none of the usual bluetooth drivers load properly (and the bluetooth icon does not appear in the bottom tray). If I then delete the drivers and re-boot, bluetooth is re-installed correctly and works fine, until the next time I have to reboot. It is consistent. I assume this is a software issue, not hardware problem. I'm working in Taiwan at the moment and took the laptop to an ASUS service center, but the technician clearly had no idea of what to do and suggested it was a hardware problem and offered to change some parts.
Extra info: I found that the update log did note an error (I can't find that now, so cannot state what it said but it was vague.) I have used two different mouses and it is not a problem of the mouse.
I've spent many hours on this, and am about to give up and simply revert to Win 8.1. This seems silly since Microsoft claimed the laptop was Win 10 compliant, and I think ASUS claims as much too. If anyone has any suggestions, I would much appreciate it.
Here is the log of the last time I rebooted and bluetooth failed to load, in case this means something to some one. Thanks.

I am having the exact same problem on a HP Zbook 17, it too seemed to start with the most recent Windows 10 update. I have found you can even just disable/enable the device, and the two additional devices "Microsoft Bluetooth Emulator" and "Microsoft Bluetooth LE Emulator" will show up, and devices will be reporting they are operating properly, and the laptop shows up to be paired on my phone or tablet.
But as JBHK reported, once I reboot I get error 43 and the two emulator devices disappear.
I have "solved" this problem by reverting to Win 8.1. Everything works fine now. To complicate matters further, after a week, I could not get bluetooth to load properly anymore. Plus, I discovered that my Olympus dictation foot pedal did not work either. After reverting to Win 8.1, everything works fine. So I don't think I'll upgrade to Win 10 on this machine. Cheers.
