The RC2 beta expires 444 days after installing. Don't remember date you installed? Run winver from commandline and it will tell you install date and expiration date.

When it expires, if you purchase a full retail version of Windows 2000, you can upgrade to the full retail version. The Upgrade versions do not support upgrading RC.

Livingston's Secret Books are a good source of information
