I am going to try & set up windows 7 pro on my macbook pro i7 2010 with parallels, & realize I will use my Microsoft product code, is there anyway or how I could get another product key or code if I wanted to install windows again with bootcamp? can this be done? I ask because, I have read that running windows through boot camp gets all of the macs resources. But I also like being able to switch between ,mac os x & windows without reboot. I figure I may just go ahead & use parallels, & if I find I need more power, I might upgrade my ram from 4 to 8gb later on down the road.
