Recent data from web analystics firm Net Applications revealed that Microsoft lost significant market share in the operating software market.

Market data share saw that October was a slow month for Windows 8 with a combined 0.36 percentage points gain. However, Windows 8 lost market share for the first time. Windows 8 fell 0.49 percentage points from 8.02% to 7.49%. Windows 8.1, on the other hand, offset the slum by gaining 0.85 percentage points. Windows 8.1 increased its 0.87% market share to 1.72%.

Industry observers believed that Windows 8 would be seeing its share of the market declining as it has urged all of its customers to get the most updated version.

2013 was not a good year for Windows 8. Research firm IDC blamed Windows 8 for the slump in personal computer sales. Since its launch early this year, global PC market declined 14% from last year to just 76.3 million shipments during the first quarter this year.

IDC program vice president for Clients and Displays Bob O'Donnell said, "At this point, unfortunately, it seems clear that the Windows 8 launch not only didn't provide a positive boost to the PC market, it's actually hurt the market. (Microsoft) is going to have to make some very tough decisions moving forward if they want to help reinvigorate the PC market."
