Microsoft officially begins discontinuing support for processors 32-bit with the release of Windows 10 version 2004, thus setting the requirement that Windows 10 only run on 64-bit machines.
Microsoft will no longer support 32-bit versions of Windows 10. Starting with Windows 10 2004, which is already available to OEMs and developers, the company is now discontinuing support for 32-bit versions of the operating system for new OEMs. The change refers to the documentation of minimum material requirements.
To be clear, this change doesn't affect existing PCs, and Microsoft says it's still committed to providing support capabilities on 32-bit versions of older machines. That means you can still buy one copy retail version of Windows 10 and use it on your existing 32-bit machine.
End of support applies to new OEM computers as 32-bit processors will no longer be supported by manufacturers chip and so these devices will slowly disappear from the market. And so the manufacturers computers OEMs will not be able to produce such machines.
Any modern computer you can buy will have a 64-bit CPU and the reason for making this change is simply because there is no demand for 32-bit computers.
If you have a 32-bit computer, there is no reason to worry and it probably won't be around for long enough. These computers will likely be eliminated from their regular support schedules unless Microsoft changes its policy at some point.
The 2004 version of Windows 10 is expected to be released later this month, and the final version is already available to users in the Windows Insider preview ring. The first production devices are expected to be updated in the last week of the month.
