The number of Windows 8 users on Steam is now more than the number of Windows XP user, according to the newly updated Steam hardware survey report for Feburary 2013 From Neowin:

While Net Applications gives an idea about how Windows 8 is doing from a more general PC audience, the tens of millions of Steam users show how the operating system is being accepted by the more hardcore PC gaming crowd. Today, the latest Steam hardware survey results are in for the month of February 2013 and it shows that Windows 8 is now ahead of Windows XP among its user base.

The new survey results show that a total of 9.63 percent of Steam users (combining 32-bit and 64-bit SKUs) have Windows 8 installed on their gaming rig, compared to 8.76 percent in January 2013. Windows XP is still being used by 9.33 percent of Steam subscribers, down from the 10.05 percent that it had in January.
