Back in December of last year I wrote about the gap closing between Microsoft’s 10 year old Windows XP OS and the new kid on the block Windows 7. Windows 7 recently passed its 18th month of availability to consumers and the sale of over 350 million licenses world wide so it is no surprise that Windows 7 continues to gain on its predecessors and, in the US, finally slip by the old diehard Windows XP.
The following two graphs are based on data from StatsCounter.com.
So on the US side there is not much else to add. From here on out Windows 7 will continue to climb and Windows XP is on the decline. That gap is quite small now but will continue to grow at a regular pace.
In the global arena the process of Windows 7 becoming the top dog is going to take a while longer. Back in December 2010 the gap between Windows 7 and Windows XP was 24.73% and according to the charts above the gap is now 14.86%. That equates to a 9.87% movement in 4 months. Based on that history and the current gap it is probably going to be around October 2011 when Windows 7 catches and surpasses Windows XP on a global scale. I think that would be quite a present for Windows 7’s 2nd birthday – don’t you?
