Hi earlthepearl,
Welcome to Sony Community!
We're saddened to hear about this. VPCEG18FG is not compatible with Windows 10 operating system. Sony didn't release any driver for this version that will support its features.
It's best to go back to the original or previous operating system. You may also try the steps provided in this link below to address the issue that you're experiencing with the laptop.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
