Hello Coconut, and welcome to Seven Forums.
When the RC expires, your Windows 7 will no longer work.
You will not need to repurchase Windows 7 though.
Before this date since you cannot uninstall the RC, you will just need to backup anything that you do not want to lose, do a clean install with the upgrade Windows 7 (click on link), and install the final RTM version of SP1.
Hope this helps,
Shawn
