Windows 10 going 64 bit only, sort of
« on: May 15, 2020, 06:30:45 am »
From Minimum hardware requirements still dated 05/02/2017:

* 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.
o Lazarus v2.1.0 r63871, FPC v3.3.1 r46876, macOS 10.14.6 (with sup update), Xcode 11.3.1

But Windows support will continue "endlessly" for win32 apps which run on Wow64.
A prominent example is MS Visual Studio 2019: It's available only as 32-bit process
and installs to Program Files (x86), regardless of install options (even if the installer
refers to 64-bit in its name, this has effect only on subcomponents of Visual Studio).

And current Win10 on ARM64 can run only x86-apps (via x86-emulation)
and native AArch64 apps, but not yet x64-apps (via x64-emulation).

Please note the really relevant part:
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.
It affects only hardware manufacturers and system builders, as the rest of the quote explains.

And those OEM distributors that still distribute 32 bit  are not many if any.
I do not understand that 64 bit windows is mainstream for over 5 years and people still ask. You should not develope new code on 32 bit intel windows at all. Maintenance is OK of course.
