Hello there,before I start,I'd like to explain the situation and what I wanted.
I have a desktop and laptop,both are genuine window.Laptop's OS is window 7 Pro and desktop is Window 7 Starter.
Since I'm the ownership,I would like to swap window 7 pro to desktop and starter to laptop.
However,I don't have CD or DVD of window 7 pro or starter.
May I ask,if there have any download link of window os can be use to download such as linux ubuntu does ? Or I must purchase its DVD from computer centre
If possible,I prefer to download it
