Microsoft has always given a good deal on an upgrade to the next generation upgrade when a customer has purchased a computer just months before its release. Often that good deal is a free upgrade, however, that is not the case with Windows 7 to Windows 8. The reasoning for this good deal is simple: if customers know the next version is right around the corner, they often will hold off which kills sales for a few months.
The fee for users to upgrade from Windows 7 to Windows 8 will be $15, according to one source. This upgrade will get you Windows Pro and no upgrade path will be offered to Windows 8 standard. The offer will be valid for users who purchase a computer after June 2, which roughly coincides with the Release Preview version of Windows 8.
Windows 8 is expected to be widely available in the second half of 2012. Microsoft will also be providing "in-the-box" upgrades packaged along with Windows 8. These upgrades will be in the form of "packs" that will provide Pro and Media Center capabilities. These packs take the place of the antiquated Windows Anytime Upgrade system.
