After the recommendation on my previous post to disable the Vista Aero in order to obtain a more efficient Vista experience, I realized afterward that I neglected to mention how to do this. For those not in the know, it's real easy: simply right (opposite) click your desktop and select "Personalize". Here you see options to change your screensaver or mouse pointer options, amongst other options.
Then open "Window Color and Appearance", and finally select the "Open classic appearance properties for more color options". Right away you will notice the "Color scheme" options such as "Windows Aero" or "Windows Vista Basic". The other "High Contast" related options tend to be more for the visually impaired or elderly. Anyway, by selecting "Windows Vista Basic" or Windows Standard" or "Windows Classic", you will endure several seconds of the change from Aero to a more basic, albeit sufficient, interface.
You will notice less sharpness in your windows, no 3-D fanciness (the "Switch between Windows" option in your Quick Launch bar, for example), etc, but again, really there is no significant change and your PC or laptop may appreciate the extra resources that will be freed up as a result.
