So I've come across a few odd issues with my Windows 8.1 Pro install (without Media Center), KMS activated. For one, I'm missing the option to get a Windows Experience score. No big deal. I'm also missing the "Add Windows Features" option. But the big problem is I can't seem to get any Streaming video via Windows 8 Apps. Netflix, Vimeo, YouTube, etc. All of them seem to refuse to buffer and play any video. Is this a symptom of not going with the Media Center option?
