Hi I have also upgraded and found the same issue with the blue tooth.
Sony Vaio Original Software Downloads
Any help appreciated!!!

VAIO Care on 32-bit and 64-bit PCs. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from computer utilities without restrictions. VAIO Care 8.4.3.7161 is available to all software users as a free download for Windows 10 PCs but also without a hitch on Windows 7 and Windows 8.
Incidently-
- Well, these are the primary problems, that might awake while updating Windows OS. The practical solution to fix such issues related to the Sony VAIO drivers for Windows 10 update, is to have the best sony drivers download. As each Windows Operating system requires the genuine laptop drivers that are compatible with the device.
- In a statement on the Sony support site for Vaio laptops, Sony posted a notice from Mike Lucas, senior vice president of Vaio for Sony. Sony has developed a firmware update for the BIOS.
I wanted to also get rid of Sony bloatware and make a clean install.
I bought a ITB SSB and put this in the machine before making a USB media windows 10 upgrade key.
The Sony Vaio has no license key sticker the Windows 8.0 license key is buried in the bios.
After I made the install of windows 10 it did not automatically find the key and was insisting I typed a product key from a license key sticker. I tried a few programs to retrieve this key (magic jelly bean etc) but nothing worked.
I put my original HDD back in the machine and upgraded this using the 'Upgrade this PC now' from windows 10 site (this method carries over all the junk from previous installs)..
This upgrade worked OK.

I still wanted the clean install so I pulled out the old drive and put back in the 1TB hard drive with the clean install of win 10.
This automatically authenticated so I have a nice clean install on a fast 1tb ssd.
All works very well (except for the blue tooth!)
