UPDATE February 9th 2010:
I am still getting emails asking how to get keys. Folks, this promotion expired June 2009, the keys are NO LONGER available. There is no way to get a key anymore.
Since my two previous posts about the PIN expiration issue I have had a LOT of feedback. Today I have some good news to pass on!
We are currently in the process of extending the expiration date, probably to the end of this month or the end of February. Please check back at http://www.registerwindowsvistasp1.com/ in the next week or so and the site should be live again for registrations.
Thanks for your patience in this matter, once the site is live again please register ASAP.
UPDATE Jan 23rd, 2009 - There are some logistical delays with getting the site back up, but I'm hopeful it will be up early next week. Sorry for the delay and, again, thanks for your patience.
