Running less code is the way to go and why my company decided to not use vista period .. vista is a hog without much to show for it other then a fancy GUI. GUI is nice when you don't care about burning resources, but most people want features they use as opposed to ones which they disable for performance reasons after a month.
 
I am glad windows 7 is going back to fundamentals.. now they need to remove the registry and provide a simple configuration switch for CIS level modes for big business to save us time from having to clean up the security holes and they will be a contender again. 

My hopes for Microsoft lay in W7, otherwise we are dumping them and converting to a *nix shop, which is a ton of work when looking at 20K+ workstations. Concentrate on automation on what is under the hood, not the gloss on the paint job;
 
Form Follows Function.
