Quick windows 8 question

[TakingBackSunday]

Thank you in advance for any answer to this question.

So I bought windows 8 when it came out a couple months ago.  I installed it on my new macbook pro, with I think like...25 gigs allocated for it.  Turns out that the amount of things I wanna do on Windows, that space was way too little.  So, I want to delete this current partition that I gave windows, allocate more space for it, and reinstall.  But will my product key still cover my old purchase?

This is the first I've really done anything in this nature.  Not to mention installing windows 8 on a retina macbook is hell if you don't have a disc drive or a large usb stick, which, um, I really don't.  So any help would be lovely.

I ... think so? I never seemed to have any problem with Office or Visual Studio product keys doing this kind of thing, it always seemed to just work. But I've heard Microsoft licensing horror stories from other people so ... ??

Bumping this for more questions.

So I have my confirmation email when I purchased the windows 8 pro license (40 bucks), but I don't seem to be able to find a way to redownload the iso file for windows 8 so I can chuck it on a USB stick.  Windows' website only gives me a .exe file to download it, but .exe's don't run on OSX.  I obviously can't just add more space to my partitioned drive for windows, so I want to just wipe that and reinstall windows 8 through boot camp fresh, but if I can't get a fuckin' iso file, this seems pretty fucked from the start.

Surely there's a way to download the ISO direct. Crazy 'ol MS. I always just leech off our work technet/msdn subcrip, yet to grab Win 8 yet though. I could grab the ISO and upload it somewhere 'safe' if you have such a place and are too scared to use torrents (RIP Usenet  :'()
