Windows 8 vies with Vista, but Windows 7 gains
Oops, Windows 7 gains in May, though Windows 8 makes headway against Vista.
Pop open the champagne. Windows 8 may be on the verge of claiming installation share victory over Vista.
Vista, one of Microsoft's least popular OSes, was introduced in November of 2006.
Then again, maybe we're breaking out the champagne too soon. Windows 7 still leads by a long shot at 44.85 percent and it actually made gains in May, up from 44.72 percent in April.
And Vista was up in Steam's rankings to 7.25 percent in May from 7.06 percent in April.
Windows XP installations were down in May to 37.74 percent from 38.31 percent in April.
