How to reserve a copy from within 10 preview?

I upgraded both of my 8.1 machines to 10 about 3 months ago and have just been using them ever since. Today I reserved my 10 upgrade on my other win7 machine. It occurs to me that I have no way of reserving an upgrade to 10 when I am already running 10. I have my product keys for 8.1 though. Anyone know if a method will be provided to those of us who have been involved in the preview to upgrade legitimately using product keys or otherwise? I don't want to reload 8.1 if I don't have to.

So, I initially did it as an update I believe, but later due to problems installed cleanly from disk. I did this on both machines. Are you saying that in order to take advantage of the free update, I have to reinstall 8 on both of my old machines? Side note, if this turns out to be the case, is there somewhere I can download an 8.1 ISO, to avoid having to load 8 first then go through the hastle of upgrade to 8.1? I only have factory DVD of windows 8

I just received an email in my MSA telling how to reserve a copy of Windows 10.
