[Development] Windows 10's EOL in Qt

[Vladimir Minenko]

Hi,

I think there is a danger in mixing different topics in one discussion.

Qt has never supported Windows Server; it was only known to be compatible so that one can make Qt build and run on a Windows Server.

I am not aware of any plans to start removing some code for Windows 10 support specifically, but this might still happen, since there will be no CI for Windows 10 for 6.13 and later. Some other code changes might come in, and no one would notice this since they have only been tested on Windows 11. If users need Qt on Windows 10, they should consider moving to Qt 6.12 LTS which will be commercially supported until 203, see https://www.qt.io/blog/windows-10-eol-plans-in-qt.

With all this, I would have no objections to having something in the code to make/keep Qt being just compatible with Windows Server.

Hi everyone,

we just removed the inoffical support for Windows Server 2016 (based on
Windows 10 [1607]) for Qt 6.13.0 [1].

Because our customers request to support Windows Server 2019 (based on
Windows 10 [1809]) until 9. Jan. 2029 [2] and Windows Server 2022
(based on Windows 10 [21H2]) until 14. Okt. 2031 [3] we would like to
no fully remove the support of Windows 10 with Qt 6.13.0.

It could be a solution when the Windows 10 specific code will not be
removed but moved into blocks with "#ifdef QT_WIN_SERVER_2019_COMPAT"
or "#ifdef QT_WIN_SERVER_2022_COMPAT". So it is still easy for people
to compile Qt for own usage with Windows Server compatibility.
