Windows 7 remained in first place with a 44.4 percent share.
Windows 8's market share during January 2013 increased from 1.72 percent to 2.2 percent. According to Net Applications, Microsoft's latest Windows operating system accounted for 2.26 percent of the OS market during January. It represents a jump from 1.72 percent in December and 1.09 percent in November.
January's figures placed Windows 8 in fifth place behind several other operating systems. It trails behind Apple's Mac OS X 10.8, which has a market share of 2.44 percent.
Windows 7 continued its dominance in first place with a 44.4 percent share, but that's a slight drop from December. Following that platform was Windows XP, which accounted for 39.5 percent of the market, a slight increase from December. In third place, Vista settled for a 5.24 percent share.
Windows 8's poor start in the market has seen Microsoft placing the blame on PC vendors for not launching enough compelling touchscreen tablets powered by the platform.
