Last month was the first full month of worldwide availability of the new Windows 8.1 OS, but according to data from Net Applications, Windows 8 and 8.1 gained just 0.05%, with Windows 8 falling 0.87% and Windows 8.1 jumping 0.92%. Interestingly, Windows 7 managed to gain more market share than Windows 8 and 8.1 combined, with a gain of 0.22%, a worrying sign for windows. Nonetheless, Windows still thoroughly dominates global market share, hovering at a cool 90.88% in total. So ultimately, the biggest concern has to be the slow adoption of the new operating systems rather than its global share more broadly.
