Get ready to shell out the cash for the GA release
If you've been using your trusty Windows 8.1 Preview
over the last couple of months, Microsoft wants to remind you that it's getting time for you to purchase the full edition. The Preview edition will be ending on January 15th, so you've got just enough time left to purchase a license before your brief look expires.
Microsoft's official blog is as thus: ”Now that Windows 8.1 and Windows RT 8.1 have been generally available for a while, it’s time to get all your remaining devices that are still running Windows 8.1 Preview or Windows RT 8.1 Preview to the final GA release before the Preview release expires."
