This was originally running windows 7. After the windows 10 update the wireless card stopped working however this is literally the only problem I have ever encountered with it. It connects to the internet hard wired just fine. I've used it for editing videos and audio files and for home multimedia (like watching movies and listening to music and stuff) for years and it's never given me a problem. And it runs super cool and extremely quiet. Win10 1TB Seagate hard drive 8GB Ram (with another slot free) i3 processor 100 firm
