I saw a post on The Green Button, showing some screenshots of Media Center in Windows 8 Build 7955 M3. This is the first time I have seen anything showing Media Center in Windows 8. There has been allot of discussion on the forums if Media Center would even be present at all?
Nothing looks to have changed with the UI yet, apart from the version number, but these pictures appear to confirm that at least Media Center is still present in this early Windows 8 build, which is good news.
If it will remain that way or if Media Center will gain any new features is yet unknown? Probably not until the first public beta release, likely to be available at the end of the year.
