For those that bought a PC with Windows 7 from June 2nd, you are eligible to upgrade to Windows 8 for $14.99 when it is released on October 26th. I am sure there are some that will prefer to stay with Windows 7 (“if it ain’t broke, don’t fix it!”), but many will want to upgrade to the latest and greatest that Microsoft has to offer.
After buying your PC, go to the Windows Upgrade Offer website to register. It will ask you to select your country (details for the offer vary depending on country). You will then be asked to register with your personal details as well as information about your Windows 7 PC purchase – including date of purchase, retailer, and PC brand and model. You should also have your 25-digit Windows 7 product key that came with the PC handy as you may be required to enter this as part of the registration.
