Steam app is now 64-bit only on systems that support it, 32-bit support enters final countdown — 32-bit users will stop receiving updates in 2026

Valve’s latest client update shifts Steam to 64-bit on Windows systems.

Tom's Hardware

Valve has previously said that 32-bit Windows installations represent around 0.01% of active Steam systems.

I feel like it’s fair to sunset 32-bit Windows support if this segment represents 0.01% of your installed base

If they’re willing to issue refunds for all games bought for 32bit.
Are there any games that won’t work on 64bit?
64 bit architecture can emulate / run 32 bit processes but the reverse doesnt work.

They could, actually. I was there, in the olden times.

Not efficiently, of course. And these days it’d be a disaster. But it was possible.

You learn something new everyday, must have been prone to mem allocation issues no?

I had the choice when buying a new PC to go with single threaded 64-bit or multiple cores. Particularly for gamin, I figured a single fire was all I really needed, and 64-bit was the future.

The correct choice at the time was multiple cores. Everything going to 64-bit wasn’t going to happen until that computer was long dead.
