            Bug ID: 43999
           Summary: GetVersion incorrectly fails to lie about the OS
                    version when masquerading as Windows 8.1 or 10
           Product: Wine
           Version: 2.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32

Windows 8.1 and Windows 10 require applications to have an embedded manifest
specifically targeting their versions before they will respond truthfully to
GetVersion, GetVersionEx, and (10 only) VerifyVersionInfo calls.

Wine answers truthfully for unmanifested applications, which is unfortunately
the wrong behavior.

says:

"In Windows 8.1 and Windows 10, the GetVersion and GetVersionEx functions have
been deprecated. In Windows 10, the VerifyVersionInfo function has also been
deprecated. While you can still call the deprecated functions, if your
application does not specifically target Windows 8.1 or Windows 10, you will
get Windows 8 version (6.2.0.0)."

https://msdn.microsoft.com/en-us/library/windows/desktop/ms724439(v=vs.85).aspx
says:

"With the release of Windows 8.1, the behavior of the GetVersion API has
changed in the value it will return for the operating system version. The value
returned by the GetVersion function now depends on how the application is
manifested.

Applications not manifested for Windows 8.1 or Windows 10 will return the
Windows 8 OS version value (6.2). Once an application is manifested for a given
operating system version, GetVersion will always return the version that the
application is manifested for in future releases."
