Valve has announced that Steam will soon stop supporting 32-bit Windows operating systems, but if you're worried that might mean you, don't fret: it almost certainly doesn't.
In a news post, Valve says that it will end support for systems running 32-bit Windows instances on January 1st next year. Essentially, that means if you're somehow still running a 32-bit version of Windows 10, it won't be supported from New Year's Day.
However, Valve quickly qualifies this announcement by clarifying that according to its Steam Hardware Survey, this decision will only apply to around 0.01% of systems, so it's very unlikely that the end of 32-bit Windows support is going to affect you (although not impossible!).
If you're still running Windows 10 and want to check whether or not you've got a 32-bit instance of the OS, all you need to do is head to the System menu, then About. You'll see whether you've got a 64-bit or 32-bit Windows version there.
Windows 11 users need not fret; there is no 32-bit version of Windows 11, so if you've already upgraded to Microsoft's latest operating system, then this move definitely won't affect you....
