can vista be tweaked?
Although Vista is new, and fast, sometimes it can seem a bit bogged down. Too many programs and not enough resources could be your problem. This could be due to having Vista Aero enabled. Aero is a resource consuming hog.
Vista Aero will literally eat up your available resources and leave you with not much left at all. Its a spectacular group of features which include helpful animations, transparent menu bars, visual effects and thumbnail previews.
Aero is installed as the default theme for Vista. Disabling this will free up tons of resources and you will notice the difference in your system once you disable it. You will still keep the Vista look, just not the resource hording effects.
One thing that you will not have will be the 3-D flip option for the desktop, so if you can live without that go ahead and disable Aero to bring your system back up to speed. If you like the 3-D flip option then leave it as is to continue as you were.
