According to the Steam November 2009 report recently released Windows XP no longer holds 50% of the market. This extremely popular operating system has been in front for many years but the first sign of the OS slipping in popularity is showing. The 32 bit version of Windows XP lost over 2 percent and dropped to 47.97 percent of all Steam users, which still means around 11.5 million gamers are using XP. Windows Vista also lost market share by 2.26 percent (down to 20.98%) for the 32 bit version and 1.8 percent (9.19%) for the 64bit version.
This means that Windows 7 64 bit version gained a huge 3.62 percent (or 1.5 million gamers) in a single month to gain a total of 13.16 percent. This is particularly impressive because it has now overtaken all the other 64bit operating systems combined. The 32 bit version gained 2.64 percent as well in one month.
When you look at the fact that Windows 7 has already almost the same user share as 32 bit Windows Vista then we can see just how popular the new Microsoft operating system really is, even in such a short time period.
It may take some time but in 2010 we would expect Windows 7 to overtake even Windows XP as the adoption rate increases via New Year computer sales and ‘word of mouth’. Our predictions are that by April/May 2010 that Windows 7 may very well be the most popular gaming OS on the planet.
