Probably Microsoft was hoping for a spike in sales during the back-to-school, but it didn’t happen. Windows 8 isn’t only declining but also has passed by the predecessor Windows 7.

The figures published by Net Applications for September cite that Windows 8 has earned only 0.61% in the last month while the market share of Windows 7 has increased by 0.80% — A leap of faith by an operating system announced in 2009.

The market share of Windows 8 is now equal to 8.02% while that of Windows 7 has exceeded 46% (46.63% to be exact). In August, however, the new operating system had increased its market share of 2.01%. Therefore, it appears that Windows 8 devices have found little space with purchases made by students before the beginning of the school year. Overall, Windows has a market share of 90.83% (-0.36% compared to August) while both OS X (7.53%) and Linux (1.64%) are growing.

The biggest concern for the Redmond Company is still Windows XP, which won’t get security patches starting April 8, 2014 and then users will be at the mercy of criminals. In September, Windows XP market share has decreased by 2.25% (from 33.66% to 31.41%). If the trend remains the same in the next six months, the rate should be even higher than 20%. Microsoft’s only hope called Windows 8.1 will go on sale from October 18.

Besides, the browser market has been practically motionless for some time. The market share of Internet Explorer (57.79%), Firefox (18.58%), Chrome (15.98%), Safari (5.77%) and Opera (1.47%) have remained almost unchanged in August with negligible changes (positive and negative), ranging between 0.02% and 0.22%. Internet Explorer 8 is still the most popular browser (21.39%), followed by Internet Explorer 10 (19.45%) and Internet Explorer 9 (9.45%). As for the competition, Firefox 23 (11.57%) and Chrome 29 (12.82%) were the most used versions when the data were collected by Net Applications.
