Lost my Vista disc -.o

[diablopath]

So, I had downgraded from Vista to XP Home a few months back because I was having a giant problem with Vista.

I have since (I think) found a solution, and I wish to go back.

...however, I cannot find my disc.

Is there any way I could obtain a new disc (or perhaps download an iso?)?
I poked a bit around the MS Website, hoping they'd have a "have a serial? HERE'S YOUR ISO", but they do not from what I can see.

Halp? :/

Phone them. They are actually surprisingly helpful.

I'd agree as well to call them. I'm guessing when you register your serial to your name, they should have a big data base of all that stuff so they know what's legit. I'm sure you could get a replacement disc for a few bucks.
