Microsoft is much harder on those that use "XP Based" designs, it is so bad that if your website has nothing to do with MS or Windows in general, they can make you remove the images (happened to one of Sinecures customers).

Unless you personally made everyone of the images, you have no right to sell them in any way, shape, or form; that is basically ripping off Microsofts images, which they paid to have done, and profiting from them.

I am not sure whether I would release it bceause of the above; free or paid, they can have you remove it. Microsoft is much larger than Apple is, of course, they do sell different merchandise, although still, if I had to choose, I would say MS would be a little more reluctant to just sue you right off if you are planning on profiting from their work.
