Looking for the specification of the Sony Vaio PCG-8K2R

check compatibility here Sony eSupport Electronics Windows 10 Information for Sony Products and Sony eSupport Windows 10 Upgrade information

I could not trace your model though.
What was the original os on it ?
Do you know the video hardware chip/card name ?

use Diver pack solution software

While I usually do driver downloads from CNet, this seems to be what you are looking for.

The manual for the PCG-K series is found here:
ftp://ftp.vaio-link.com/pub/Manuals/Notebooks/K3/K3_H_EN.pdf
The specifics of the K315S model don't appear to be anything but minor variations of each other (such as more ram, different hard drive, or larger/smaller screens) so this manual should cover all the basic functions of the laptop.
Since this appears to be a laptop made for European markets you can use this website to find drivers and other documentation: http://support.vaio.sony.eu/computing/vaio/index.aspx
You will need to enter your serial number off the labal on the bottom of the machine.
Hope this helps!
