### enum QSysInfo::WinVersion

This enum provides symbolic names for the various versions of the Windows operating system. On Windows, the QSysInfo::WindowsVersion variable gives the version of the system on which the application is run.

MS-DOS-based versions:

`QSysInfo::WV_98` | `0x0003` | Windows 98
`QSysInfo::WV_Me` | `0x0004` | Windows Me

NT-based versions (note that each operating system version is only represented once rather than each Windows edition):

Constant | Value | Description
--- | --- | ---
`QSysInfo::WV_NT` | `0x0010` | Windows NT (operating system version 4.0)
`QSysInfo::WV_2000` | `0x0020` | Windows 2000 (operating system version 5.0)

`QSysInfo::WV_4_0` | `WV_NT` | Operating system version 4.0, corresponds to Windows NT
`QSysInfo::WV_5_0` | `WV_2000` | Operating system version 5.0, corresponds to Windows 2000
`QSysInfo::WV_5_1` | `WV_XP` | Operating system version 5.1, corresponds to Windows XP
`QSysInfo::WV_5_2` | `WV_2003` | Operating system version 5.2, corresponds to Windows Server 2003, Windows Server 2003 R2, Windows Home Server, and Windows XP Professional x64 Edition
`QSysInfo::WV_6_0` | `WV_VISTA` | Operating system version 6.0, corresponds to Windows Vista and Windows Server 2008
`QSysInfo::WV_6_1` | `WV_WINDOWS7` | Operating system version 6.1, corresponds to Windows 7 and Windows Server 2008 R2
`QSysInfo::WV_6_2` | `WV_WINDOWS8` | Operating system version 6.2, corresponds to Windows 8
`QSysInfo::WV_6_3` | `WV_WINDOWS8_1` | Operating system version 6.3, corresponds to Windows 8.1, introduced in Qt 5.2
`QSysInfo::WV_10_0` | `WV_WINDOWS10` | Operating system version 10.0, corresponds to Windows 10, introduced in Qt 5.5

The following masks can be used for testing whether a Windows version is MS-DOS-based or NT-based:

Constant | Value | Description
--- | --- | ---
`QSysInfo::WV_DOS_based` | `0x000f` | MS-DOS-based version of Windows
`QSysInfo::WV_NT_based` | `0x00f0` | NT-based version of Windows
`QSysInfo::WV_None` | `0x0000` | Operating system other than Windows.
