Hello, I read that the offer will end on July 29. I have been using Windows 7 Professional 64-bit via Bootcamp for over 10 years. Not sure if there will be compatibility issues between Windows 10 and software of over 10 years old. I guess the upcoming 2016 rMBP may not support Windows 7. What suggestion do you have? Can I get a free update disk and license before July 29 and then decide what to do when Apple releases a new rMBP later this year?
