Vista, thy name is bloat! The latest Windows packs a lot of code -- more than any version of Windows ever -- and some of it is just plain unnecessary. All of that excess code has a way of slowing down an operating system. You can regain some PC performance by removing unneeded features.
InfoWorld have identified a dozen Vista features that you can turn off right now. Some are shiny baubles that slow down graphics performance, while others are optional utilities that hog memory when they shouldn"t. A few can actually be quite useful, though they play a major role in bogging down your PC.
