Why are you using 1, 2, 3, etc. when you want Windows, Linux, etc.?
Perhaps this little example will help:
<?php
if( isset($_GET['OS']) ) {
foreach( $_GET['OS'] as $key => $value) {
printf("Selected %s<br>\n", $value);
}
}
?>
<html>
<head></head>
<body>
<form action="test.php" method="GET">
<select name="OS[]" size="5" multiple>
<option>Windows</option>
<option>Linux</option>
</select>
<input type="submit">
</form>
</body>
</html>
