1. Executive Summary

The Sony Vaio PCG-81114L was originally designed for Windows 7 (or Windows 8). Sony exited the PC business in 2014, meaning official drivers for Windows 10 do not exist from Sony. However, the hardware is compatible with Windows 10 using a hybrid approach: Windows Update + Intel reference drivers + some modified Sony utilities. The main challenges are function keys (Fn), Sony specific power management (Vaio Control Center), and the SD card reader.
