What are the potential pitfalls of using the WMI class Win32_Product in PHP to retrieve software versions?

One potential pitfall of using the WMI class Win32_Product in PHP to retrieve software versions is that it can be slow and resource-intensive, especially on large networks with many installed programs. This can lead to performance issues and delays in retrieving the information. To solve this issue, it is recommended to use alternative methods such as querying the registry directly or using a more lightweight WMI query to retrieve the necessary information. 

<?php
$wmi = new COM('winmgmts:{impersonationLevel=impersonate}//./root/cimv2');
$software = $wmi->ExecQuery("SELECT * FROM Win32_Product");

foreach ($software as $app) {
    echo $app->Name . " - " . $app->Version . "\n";
}
