A new video over at Microsoft's Channel 9 talks about the new install technology of Windows Vista.
Windows Vista evangelist Ernie Booth came into my office a few weeks back and said "hey, let's go interview the MSI 4.0 team." Who's that? That's the team that makes the application install technology that'll ship on Windows Vista. Your app will probably use their technology to install, so you'll want to hear this and see the demos they do for us.
