Hello everyone. I'm pretty new over here, in fact, I just registered 2 minutes ago.
I came here to ask if it's possible to port a theme for Windows 7 to Windows 8.1 somehow.
I'm really interested in this black version of Windows 7's Basic theme but I really don't have a clue on how would I go about porting it.

Or at least I'd like to know if it would be possible to grab an already existing Windows 8.1 custom theme and change its colors somehow.
That might be an easier option to take considering that someone already recreated the Windows 7 Basic theme for Windows 8.1 right here.

Thanks in advance for reading
