While not many saw it coming, it was only waiting to happen. New Windows 10 PCs, starting with the May 2020 Feature Update (version 2004), will be able to run 64-bit Windows 10 only. That means any new hardware you are going to buy will eventually be 64-Bit only, which not only offers support for more RAM, Storage, and powerful configuration, which is limited with the 32-bit version.
New PCs will be able to run 64-bit Windows 10 only
The excellent news that existing PCs are unaffected. If you have 32-bit hardware running Windows 10, then you will still get the update via Windows 10 Update. The information comes via the Microsoft minimum hardware requirement page, which indicates the phasing out of the 32-bit version of Windows.
Beginning with Windows 10, version 2004, all new Windows 10 systems will be required to use 64-bit builds and Microsoft will no longer release 32-bit builds for OEM distribution.
This does not impact 32-bit customer systems that are manufactured with earlier versions of Windows 10; Microsoft remains committed to providing feature and security updates on these devices, including continued 32-bit media availability in non-OEM channels to support various upgrade installation scenarios.
Since Microsoft is not going to offer a 32-bit version to OEMs, it means they will not be able to test, and hence when you buy a new Windows 10 PC, it will come with the 64-bit hardware. It was a much-needed space because some of the hardware sellers been selling underpowered Windows 10 PC, which had never been appropriately tested. Those tablets delivered a bad experience, and the end-user would only blame the operating system over the hardware.
If you are still on a 32-bit version, it is about time that you upgrade to 64-bit. Since OEMs will not have access to newer versions of 32-bit any more, it means all they will rollout are minor updates to the drivers or anything that OEMs have developed.
Microsoft recently made the ISOs available on MSDN, and they were all 64-bit versions.
