I can see this in the future
Something tells me Microsoft is preparing the terrain for the juicy subscription model. You decide what you want to do with Windows 10, Microsoft installs only those components that are necessary and charge you for anything you would like to add on top of that. Something like, oh you need media player ? Sure, it's available for you at only 4.99$ /month. Add to this a careful bundling of add-ons in packages increasing the chance that you will be forced to buy at least two in order to get what you need, the same thing we're seeing with cable TV programs. Sell/lease the base line and charge for add-ons, this is the future. Heck, even BMW intends to do it with their cars so why not Microsoft with their OS ?
