Update minimal supported OS version to Windows 10 1809 #1456
Description
Description
Since #1329 Mozc for Windows has required Windows 10 1507 or later to be installed. It's probably time to bump the minimal required version from Windows 10 1507 to Windows 10 1809.
Here are rationales:
- Qt 6.9.1, which we currently use, requires Windows 10 1809 or later as the minimal supported version already. Luckily Qt 6.11.1, which we are going to switch to at
build_qt.pyfails with Xcode 26.4 on macOS #1455, still requires Windows 10 1809 as the minimal supported version. - To fully support Per-Monitor DPI v2 protocol in Windows (Conform Per-Monitor DPI v2 protocol in Windows #831), APIs such as
GetSystemMetricsForDpineed to be used. Such APIs were available in Windows 10 1607 and later.
Steps to reproduce
- Try to install Mozc for Windows
Expected behavior
- You can install Mozc for Windows only on Windows 10 1809 and later.
Actual behavior
- You can install Mozc for Windows only on Windows 10 1507 and later.
