Windows Aero on Business

So I have Windows Vista Business and I would like to use Aero but all that's available is Basic (along with the old stuff). How do I get Aero?

Vista Business should include Aero, so it may have been disabled for the sake of performance. The simplest solution might be this Microsoft Fix-it: https://support.microsoft.com/en-us/mats/aero_effects_not_working/en-us

Aero is not disabled simply because you are using the business version. It is disabled if your graphics card or drivers don't support it. Try updating your drivers. Without knowing more about your computer we can't help you with that.
