We are selling it because we do not use it. The product is in working condition. Windows 10 is installed. But ethernet does not work with windows 10 (there is no ethernet driver for windows 10), so you can use ethernet by installing windows 8 or windows 7. If you want to use it as Windows 10, you can connect to the internet from USB ports.
