Windows 8.1 has finally bested its predecessor, with its market share edging higher than Windows 8′s in May, according to NetMarketShare. In May, Windows 8.1 ended with 6.35% global desktop market share, while Windows 8 managed a slimmer 6.29%. As The Next Web’s Emil Protalinski notes, that’s an aggregate gain of 0.40% for Microsoft’s new Windows 8.x platform. Here’s a plus, and a minus: While Windows XP’s market share fell over 1% in the month to 25.27%, Windows 7 saw is market share skip past the 50% line. So, it seems that large companies are moving from Windows XP to Windows 7, a shift that Microsoft has encouraged, is material.
