Description

Currently our installer for Windows does not strictly enforce the target machine to be Windows 10 or higher.

We should be able to specify the minimum supported build number to the installer.

Steps to reproduce

1. Try to build Mozc64.msi with a certain minimum supported Windows build number, say 26100 as Windows 11 24H2.
2. Try to install Mozc64.msi into an earlier version of Windows, say Windows 11 23H2.

Expected behavior

The installation will fail with a clear message.

Actual behavior

Currently there is no way to specify the minimum supported Windows build number.

• Microsoft also stopped supporting older versions of Windows 10/11 in the consumer channels.
• Extended Security Updates (ESU) program for Windows 10 will be offered to Windows 10 22H2 (build number 19045) only.
• Here is the mapping table between Windows 10/11 releases and their build numbers.
