Windows 11 hits a new PC gaming milestone on Steam with over 70% market share — Windows 10’s time is running out

Despite decades of people calling for “the year of Linux,” fresh data from Steam’s Hardware Survey for June 2026 suggests Windows is still firmly the norm. Linux’s market share fell by 0.30 percent to 3.69%. Yes, that’s a relatively small decline, but considering Linux’s smaller gains have often been celebrated, I think it’s only fair to mention it. To keep things balanced, though, Linux is still well ahead of where it was this time last year, when it sat at just 2.57%.

Before we jump into what we all actually care about (Windows), macOS also saw a small increase, rising by 0.05 percent to 2.21%, up from 1.76% this time last year. I know rattling off percentages can get a little mind-numbing, but there are actually some genuinely interesting trends hiding in this month’s data, so let’s get into the Windows side of things, because that’s where things get particularly interesting.
