Windows 8.1 is available for download. Those who already have Windows 8 installed can get it for free from the Windows Store, as described below pictures.
If you run Windows 7, Vista or XP, Windows 8.1 is only available as a standalone purchase. The license will cost 90 euros, while the Pro version will be 150.
Microsoft with this version is trying to fix many issues that made Windows 8 users unhappy. Its sales have not been the best as Windows 8 has acquired quite a controversial name in the market. Will they fix things? No one knows. With the upgrade we will find out, although the changes that are coming do not concern the core of the system but rather its external appearance. Is "look" more important than "is" for Microsoft?
