Microsoft started rolling out its Windows 10 Fall Creators update on October 17, but it failed to impress the Steam gamers who are apparently returning to Windows 7.

According to the latest statistics, Windows 10 64-bit lost around 17.14 per cent of its share on the gaming platform, which is probably the biggest drop an OS has ever experienced on Steam.

On the flip side, Windows 7 64-bit recorded an impressive surge of up to 22.59 per cent, becoming the top desktop OS for gaming with 63.60 per cent. Windows 8.1 is on the third spot with 3.09 per cent shy from Windows 10’s 28.23 per cent current Steam share.

There could be many reasons for the sudden decline in the share, including inaccurate data from Valave, it turns out that another substantial share change was experienced in the case of languages being used to play games on Steam. In the month of October, English lost the number one language spot dropping by 13.40 per cent to 21.24 per cent, with Chinese going up by 26.83 per cent to reach 56.37 percent of the computers that are running Valve’s gaming software.

This could be a possible reason of the sudden increase of Windows 7, since Chinese users are more likely to use the 2009 OS given the high piracy rate in the country.

Even after the sudden decline, Apple still doesn’t pose a threat to Windows, considering the macOS only powers up to 1.60 per cent of the systems used for playing games on Steam. The same goes for Linux as the open-source platform only supports up to 0.35 per cent of the gaming computers.

macOS and Linux users have second OS - Windows for gaming.
