While Microsoft is making no secret of the fact that Windows Vista’s licensing terms will only allow one transfer of the operating system to another machine, the company has revealed that enthusiasts who upgrade their PCs often may not be as inconvenienced by those terms as some might think. The guys over at Bit-Tech have heard straight from the horse’s mouth that Microsoft will only require users to re-activate their copy of Vista if the main hard drive and one other component of their PC is changed. Furthermore, users who go through such upgrades will be allowed to re-active their copy of Vista up to 10 times. Microsoft may or may not decide to allow additional re-activations at its own discretion. For smaller upgrades like graphics cards, processors, or memory, Microsoft is quoted as saying that Vista won’t need to be re-activated at all.
