I did a clean / keep nothing upgrade on my Vaio Pro 11 (Mid 2014 - originally shipped with Windows 8) via MS' Media Creation tool and it's far better with Windows 10 than it ever was with 8 or 8.1.
With 8.1 I had to use an outdated Sony version of the Intel chipset / VGA drivers to get the HDMI port working, and WiFI was flaky on 5GHz networks. On Windows 10 everything worked out of the box and the only thing that I had to track down a driver for was some Sony system management firmware device.
All in it took about 2 hours to upgrade, patch and get back up and running.
Biting the hand that feeds IT
