I have the zx6971 running windows 8 64 bit pro. my remote was not working initially until i downloaded all the drivers from here: http://support.gateway.com/ca/fr/product/default.aspx?modelId=3931.
I downloaded and extracted all the files myself and ran all programs labled "application". then i downloaded the free media center thing (after waiting almost 24 hours for Microsoft to email me a product code) and now it works fine. it no longer has netflix
on it but you can download the app to your main tile screen and use the remote to access it there (which i actually like better).
unfortunately my touchscreen is not working either. I've spent hours researching and talking to my IT people and it looks like we'll just have to wait for gateway to get on the ball and release
a driver for us. Its is definitely not a windows 8 issue, its a gateway issue, so hopefully they get their act together soon!
