From what i read about code 10 error message the only way to know for sure if its hardware or software related is to re-install your system. Hopefully it's software and bluetooth is working fine.
Buying the usb dvd also gives you the benefit of being able to use dvd's as well with the tablet and importantly allowing an easy method to re-install your system. Don't forget before starting the re-installation of your system to download all the updates from the Acer site.
All your mail/contacts/bookmarks/ModernUI apps should be backed up automatically online if you use your Windows ID to log into your system. I would check first though (go online and see if they are there) and export your bookmarks via IE desktop. Your desktop apps don't get backed up so they may require backing up. Having a collection of computers of my own I re-install so often I'm so use to backing up data online (via skydrive, google drive and dropbox) as well as using an external drive.
Ten years ago, when supports system had no solution, they said "format c:".
OK, for a code 10, it's only a driver problem. A bad transmission between installed driver and Device Manager.
So, don't reinstall Windows. Or do it if your headache is too painful!
As i've seen in W700 BT driver (i download it to be sure), it's coming from Atheros and not from Qualcomm. So, if you can't uninstall this driver, disable it and install the Atheros one. Second solution: disable Qualcomm, reboot and after boot, W8 will ask you about BT driver. Give the path for Atheros.
I have a some problems on my W700, even upgraded to win 8.1, the problem was still existed, but when i downloaded and installed a fresh came out BT driver(2013/10/17), everythings back to normal now, everybody just go and try!
