We have spoken often on this blog virtualization, Last post on Moka5. As I also said in the episode of the podcast which addressed the topic, one of the first things I recommend is to try to come closer to your linux using virtualization software. E 'out today on Lifehacker (if you have not realized that more than one of the blogs I follow on the Internet) as a guide for beginners which relates to this subject.
Some time ago he published an article that dealt with the opposite problem, how to use Windows applications under Linux, this very interesting.

Both articles are in English, if you need help do not hesitate to ask, I'm sure that many will be ready to help.
