Of the above internal Microsoft video, Gizmodo's Adam Frucci says all that needs be said:
You've gotta wonder how, in a company the size of Microsoft, there's not a single person who has the balls to step up and say "Hey, you know what? This Vista music video we're making for the sales department, complete with a cheesy Bruce Springsteen impersonator and horrible music, damages the dignity of not only everyone involved in its production, but everyone who watches it." Seriously, how did this little slice of cringe-inducing embarrassment ever get made? What year is this? I need to lie down.
I've got nothing to add.
