Here's one way: 
use warnings;
use strict;
use Win32;
my ($servicepack,$major,$minor,$build,$id) = Win32::GetOSVersion;
my $os;
my $version = $major+($minor/10);
$version = sprintf "%2.1f", $version;

if    ($id == 0 ) { $os = "Win32s"; }
elsif ($id == 1 ) { $os = "Win95";  }
elsif ($id == 2 ) { $os = "WinNT";  }
else              { $os = "Unknown"; }

print "You are running $os version $version with $servicepack\n";
