The total of the operating systems that won't be supported anymore after the end of 2023 is 1.94%. Windows 7 is listed there with 1.58% and Windows 8.1 with 0.36%. Valve's hardware survey for February 2023 provides insights on the operating systems that are used by Steam users.

In the worst case, Steam customers may no longer be able to access their purchased games on the platform. The installation of Linux on these devices would also ensure that Steam can be run on the devices after January 1, 2024.

There is another option available though, which Valve Software does not mention. Steam users who can't upgrade their devices won't be able to use Steam anymore on the platform.

Upgrades to Windows 11 may not be possible for many machines, as Microsoft changed the system requirements when it released Windows 11. Most Windows 7 and 8.1 devices can be upgraded to Windows 10, as the newer operating system has the same system requirements than the older versions. Valve Software recommends that Steam customers upgrade their devices to a supported version of the Windows operating system. Future versions of Steam will use security features and non-security features that are only present in Windows 10 and newer versions of the Windows operating system.Since Google ended support for Windows 7 and 8.1, newer versions of Chrome won't run on devices with these operating systems anymore. Steam uses an embedded version of Google Chrome.Valve provides two reasons for its decision to end support for the unsupported Windows operating system versions: Several companies, including Google and Microsoft, have announced end of support for some of their software products for these operating systems already. The operating systems are no longer supported, which means that they do not get any updates, security or otherwise, anymore. Microsoft ended support for Windows 7, Windows 8 and Windows 8.1 in January 2023. Valve Software, the company behind Steam and maker of smash hits such as Half-life or Counter-strike, has announced the end of support for the Windows platform on the Steam support website.
