            Bug ID: 56795
           Summary: Windows version is detected as outdated by
                    XboxInstaller.exe
           Product: Wine
           Version: 9.10
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs(a)winehq.org

      Distribution: ---

The Xbox App installer has a minimum requirement of Windows 10 19H1 or higher.
However, even when the version is set to 10 or 11, the app shows a message
saying that the version is outdated and that an update has to be performed
before the installer can run.

The GetVersionExW() function in dlls/kernelbase/version.c is returning version
information for Windows 8 instead of 10. This happens because of this line in
init_current_version, where the RtlImageNtHeader has the version 4.0 so it
defaults to Windows 8 as the reported version.

This looks intentional, so maybe the real issue is that the
IsWindows[x]OrGreater functions are missing from wine.

Note, it is only possible to start the app without crashing if this patch is
applied:
