Microsoft would like to remind you that you have until January 31st of this year to be eligible to snag Windows 8 Pro for $14.99 via the Windows Upgrade Offer. In order to qualify, you must have purchased or received a Windows 7 PC anytime between June 2nd 2012 and through January 31st 2013.
"So if you received or purchased a Windows 7 PC over the holidays, you can take advantage of this offer and register to purchase the upgrade. Windows 8 has a lot to offer when upgrading from Windows 7 including a beautiful new Start screen with live tiles, plus the familiar desktop and faster startup and longer battery life," Microsoft stated in an official blog post.
Once you register for the Windows Upgrade Offer, you will receive via email a promo code. You can enter that code during the Windows 8 Pro upgrade process. "You then go to Windows.com to buy a Windows 8 Pro upgrade like you would normally through the Windows 8 Upgrade Assistant (I blogged about the Windows 8 Upgrade Assistant here). When you get to the point in the process where you are asked to confirm your order, you are given the opportunity to enter the promo code you were sent by registering for the Windows Upgrade Offer and the price of Windows 8 Pro will then drop to $14.99 (U.S.)," Microsoft explains. The code you receive via email is the code that allows you to have Windows 8 Pro for $14.99.
