How to make Make OS X behave like Windows XP/Vista/7?

Ok, I feel unclean making this request, but it's for a good cause. My wife H.A.T.E.S. her Mac Mini. She's a particularly stubborn form of Windows user that grumbles about the differences in the Mac/Windows UI at every available opportunity. In order to make her happy and keep my sanity, I want to do everything in my power to make her OS X experience as comfortable (windows-like) as possible. I would greatly appreciate any suggestions anyone might have!!! Oh, and installing Windows on her Mini isn't a valid option. It's one of the early Intel models with limited RAM/HD and she's also a heavy iPhoto user so I don't want to make her switch back and forth. This is your chance to help save a marriage 😉
