actually yes it is free. you can go out and find everything you changed for free, only diff being you got it all in 1 package. (i was refering to the background as just being a background pic) one can obviously find that.
the windows skin, thoes are free, i found an xbox one easy as can be.
icon changers, also easy to find, i have many, but i dont like game themed ones.
logon screen. yes also free, but thoes arent the best things to mess with, you can actually screw up your system to the point where it doesnt boot by messing with that logon screen. but yea. you can find em.
you can also change the whole gui.
and btw, for the stuff i mentioned, you need no program to run any of it.
www.themexp.com has some. but its a slow site. annoying to work with.
or
www.wincustomize.com
there are others. skinz.org. etc.
