Vista, that’s what ruined it for me. I had XP Pro, and I loved that it had all the features (IIS, FTP Server, etc.). But when Vista came out, it had so many different versions, each one a gatekeeper for different features. That was just too much. XP was the last one I used for my personal use. I jumped into Linux, head first, and I’ve never looked back.
I have them blocked on Steam. I don’t care what comes from them, it’s not worth it.
