it was good in beta and RC, better than vista when it was officially out, and cuz its based on the vista core, anything that works with vista works with windows 7, that included COD4 and Crysis and so on, for some programs, u might need them to run in compatibility mode for vista because it will not recognize windows 7 as a compatible OS and say something like its only supported by xp and vista, or it needs vista or newer, though it is newer, it dose not no that, when u put it in compatibility mode for vista it will think its on vista, and work just great with 7
