After the sheer horror that was Vista, Microsoft looks to have got things back on track, with Windows 7’s strong 2009 holiday season sales being reflected in a growing OS market share.
The operating system now has a bigger overall market share than all the tracked Apple OS X versions (10.4, 10.5 and 10.6), even if the total Windows market share dropped 0.31 percentage points (from 92.52 percent to 92.21 percent) between November and December 2009 .
The Mac OS also saw a slight reduction in market share of 0.01 percentage points (from 5.12 percent to 5.11 percent) while Linux was the only OS to show growth, shimmying forward 0.02 percentage points (from 1.00 percent to 1.02 percent).
