If you register then you have the one year period to upgrade. The only way to get your upgrade key is to upgrade and use a keyfinder like magic jellybean. Although I've heard some people have received their key in an email. I haven't personally seen an email as such. If in fact you do get it via email then you can upgrade at any future time.
OK well, the upgrade is on the insiders website and the reservation on my pc right? and once i get the upgrade what happens do i have to pay anything later? Neemobeer do you have a skype or something?
