Hi All,
I am trying to see if the Windows version I am using is newer than Windows 7 or Windows Server 2008 R2 (minimum requirements). I googled a bit and run into your post. Here is my question, I am running on Windows 10 machine and these lines:

 
print ("(\$ENV{\"OS\"}: " . ($ENV{"OS"}) . "\n");
    use Win32;
    print "GetOSName: " . Win32::GetOSName() . "\n";
    use Config;
    print "$Config{osname}\n";
    print "$Config{archname}\n";
    print "$Config{osvers}\n";
    my ($name, $major, $minor, $build, $id) = Win32::GetOSVersion();
    my %versions = (
    0 => {'' => {'' => "Win32s"}},
    1 => {
        4 => {
            0  => "Windows 95",
            10 => "Windows 98",
            90 => "Windows Me"
        }
    },
    2 => {
        3 => {51 => "Windows NT 3.51"},
        4 => {0  => "Windows NT 4"},
        5 => {
            0 => "Windows 2000",
            1 => "Windows XP",
            2 => "Windows Server 2003"
        },
        6 => {
            0 => "Windows Vista or Server 2008",
            1 => "Windows 7"
        }
    },
    );
    
    print "version: " . $id . ", " . $major . "," . $minor . "\n";

yields me:

($ENV{"OS"}: Windows_NT
    GetOSName: Win2003
    MSWin32
    MSWin32-x86-multi-thread
    4.0
    version: 2, 6,2

My questions are:
1) How can I see it is windows 10? Why do I receive "Windows_NT" and "Windows2003" in my first two lines?
2) @marto why do I get the version to be 4.0?
3) @GrandFather, I looked into the link you posted http://search.cpan.org/~jdb/Win32-0.52/Win32.pm, but all I see there is a table of:

        OS                      ID    MAJOR   MINOR
    Win32s                   0      -       -
    Windows 95               1      4       0
    Windows 98               1      4      10
    Windows Me               1      4      90

    Windows NT 3.51          2      3      51
    Windows NT 4             2      4       0

    Windows 2000             2      5       0
    Windows XP               2      5       1
    Windows Server 2003      2      5       2
    Windows Server 2003 R2   2      5       2
    Windows Home Server      2      5       2

    Windows Vista            2      6       0
    Windows Server 2008      2      6       0
    Windows 7                2      6       1
    Windows Server 2008 R2   2      6       1
    Windows 8                2      6       2
    Windows Server 2012      2      6       2

Where is Windows 10, 2016 and other which are newer (regular/server) from the requirement I wrote?
