I am not sure which thread i posted this but i will say it again.
Windows 7 right now will look almost exactly like Windows Vista as the code they use is the same at first. They make minor changes to it to show the new OS version and things like that but the first Milestone builds all look like the previous OS. Longhorn looked exactly like XP till it went into Beta.
But here is a thought that crossed my mind. How are they using the same code? They are using the new MinWin kernel. Which is a small kernel compared to the one used for Vista. It is supposed to cut down on the size of the OS majorly. So how can they use the code for Vista when they are 2 different kernels? I will have to find out about this thought.....
