Registration for £14.99 Windows 8 upgrade offer now open

Microsoft has started accepting registrations for Windows 8 upgrades. Those who purchased a PC anytime after 2 June can now sign up to receive the Windows 8 upgrade for £14.99 when the OS is released on 26 October.

Back in May, Microsoft announced that anyone who purchased a Windows 7 PC between 2 June 2012 and 31 January 2013 could upgrade to Windows 8 Pro for £14.99. Registration for that offer is now live via for PC users in 140 countries.

After selecting your country, Microsoft will ask you to register your personal details and information about your new PC, including date of purchase, retailer, and PC brand and model. You'll also need your 25-digit Windows 7 product key.

On 26 October, Microsoft will start sending out promo codes via email. When you upgrade via, Microsoft will display the £49.99 price for general upgrades; enter the promo code on the confirmation page to get the £14.99 price.

Users have until 28 February 2013 to use their promo code.

Those who bought a PC before 2 June or have an older Windows 7 PC they'd like to upgrade can get Windows 8 Pro for £39.99 via starting 26 October. If you'd like more details about the operating system before taking the plunge, check out our first look at the RTM version.

In recent weeks, Microsoft announced that it will no longer be using the term "Metro" to describe the mobile-like interface within its new OS. Redmond said "Metro" was a codename all along, but there were reports that Microsoft stopped using the name because of a trademark challenge from Germany's Metro AG.
