Windows XP is almost old enough that revisionist historians can have a crack at it without anyone speaking out against it. That is, it would be if not for the large number of users still using the operating system at their home and work. The decade old operating system has only now fallen below 50% of Windows’ market share. More specifically, the slip in market share occurred between June and July where it fell 0.63% to a total of 49.94%.

The numbers are percentages of MS’s total 87.66% market share.

In comparison, Windows Vista holds a much smaller 9.24% market share after dropping 0.28%. Microsoft’s most recent operating system, Windows 7; meanwhile, saw a gain of 0.74% to a total of 27.87% market share, which puts the new operating system well on its way to overtaking the XP juggernaut. Techspot has the full scoop on the market share situation, which you can read about here.
