100 of millions of people won't have Windows 10 though and they already know about the X1.This won't promote the console any better as MS already does something similar with Windows 8.

Actually, there will be 100's of millions with Windows 10. All users of Windows 7+ will get Windows 10 for free. 

yep, and given windows 10 seems to have corrected the UI mistakes that windows 8 made and introduces more performance improvements it should have relatively fast adoption, maybe even faster adoption than Windows 7. How success the app being front and centre is will depend entirely on what functionality comes with it, if it is just the win 8 one dressed up it isn't going to do much, however if it is the start of a much more cross platform integrated experience then it has potential to be huge, cross platform streaming would be monumentally massive if they did it, though I would not be holding my breath on that one in the short term.
