That's outdated info . Microsoft decided they wanted the OS out ASAP and stripped features INCLUDING Longhorn being based off of .NET. <{POST_SNAPBACK}> Sure they want it out ASAP, my belive is that the primary this days is to implement that TC/Fritz-chip in our systems. The debate/actions around copyrights/pirated material has taken proportions big enuff to make the move to throw it out prematurely, I can assure you that part with Trusted Computing (or whatevva they choosen to call it now) related stuff is fully developed.... <{POST_SNAPBACK}> Trusted Computing still has a long way to go. The current 5048 build doesn't implement any of the security features Microsoft promised.
Custom buttons are possible with Explorer (I think). There was this Powertoy for Internet Explorer that added files to trusted/untrusted zones. I'm sure you can modify it to change another registry key instead and to work with Explorer. The file is available as an IE5 powertoy.
I came across an article once that showed how fast a fresh install of SP1 would become infected compared to SP2. I don't remember the exact times, but SP1 became infected in ~15 minutes, while SP2 never got infected.
