Here is an excellent write up by none other than Microsoft themselves. It’s a great article going into detail about what is new and improved with Vista. I’m sure you’ve heard the majority of it all but this stuff is interesting due to the under the hood nature of the details. It’s much more complex than the normal, “you are much more secure with Vista, blah blah blah.” This delves into much more detail. Read it, I hope you like it. I got it off digg.com.
