Windows XP is still the dominant OS worldwide after more than 10 years, but Windows 7 continues to narrow the gap.
XP ended last year with a 46 percent slice of the OS market, according to December data from NetApplications. Although impressive after a decade, that number proved a hefty drop in use for XP, which kicked off 2011 with a 55 percent share and has fallen each month since then.
When XP support ends in 2014 we may see more people upgrade, but until then we're seeing a lot of natural upgrades that come when people upgrade their hardware.
I upgraded all of my XP machines to Windows 7, but I may not be considered an average user. ;)
