All Microsoft OS from XP are linked to the hardware in the computer to prevent implementation on other computers, however unlike Apple with its limited, extortionate expensive upgrades, you can stick anything YOU (Not what Apple says you should have) want into a PC, which means it has to be more flexible.

Regarding DRM, have a look around, as manufactures and distributors are dropping it at an ever increasing pace.

Regarding Styles, unless you prevent the arranger engine from being able to output them, (Great for open keyboards as everything is loaded internally, but for 90% of players a complete No No) protection would not be possible. (Users already complain that some keyboards are difficult to use external software/hardware with the style engine)
