Valve updated its Hardware & Software Survey today for January, revealing that more than one in every three gamers on Steam is now using Windows 10. The latest and greatest from Microsoft may have just passed 11 percent market share, but on Steam the adoption rate is already at 34 percent.

In its first month, Windows 10 adoption on Steam passed Windows 8, Windows Vista, Windows XP, Mac OS X, and Linux. After two months, Windows 8.1 was also conquered, leaving just Windows 7. Six months in, it’s getting very close at dethroning the top dog.

Here is the January operating system market share list for Steam:

• Windows 10: 34.05 percent
• Windows 8.1: 14.43 percent
• Windows 8: 2.06 percent
• Windows 7: 42.08 percent
• Windows Vista: 0.42 percent
• Windows XP: 2.31 percent
• Mac OS X: 3.55 percent
• Linux: 0.95 percent

Windows 10 is poised to pass Windows 7 this year, probably in the next few months. Other Windows versions are losing adoption on Steam, meaning Windows 10 is gaining more than Windows 7 is losing.

Breaking down the numbers even more, here is how each operating system version fared:

Between December and January, Windows 10 jumped 1.59 percentage points — a small increase compared to months in 2015. These gains have to come from somewhere: Windows 8.1 dropped 1.06 points, Windows 8 slipped 0.14 points, Windows 7 fell 0.50 points, and Vista dipped 0.03 points. XP somehow managed to gain 0.14 points, but this is merely a blip and nothing to significant.

On the whole, Windows still dominates Steam with over 95 percent share. Mac and Linux slipped 0.01 points each in January.
