So you just need a few more days time without Win 7 nagging you.
That's where we can help.
If you borrow someone else's Windows 7 disc you can use the data to upgrade your RC1 to RTM status for up to 90 days longer, because a Windows 7 license status is determined not by its disc, but by its key. This is how IT managers roll out dozens of OS updates across a network from a 'single disc'.
As it stands though, just dropping in the Win 7 disc and hitting 'Upgrade' won't allow you to go from RC1 to RTM, but there is a hack involved to do this.
Before you start make sure you BACKUP EVERYTHING IMPORTANT and close your programs. I cannot stress this enough. It's not my fault if there are complications in the process and you lose a lifetime's worth of family photos and videos. I have personally done this twice now without issue, so it's highly unlikely anything bad will happen, but still, on your own head be it.
