Executing commands may hang on Windows XP for some programs

[GoogleCodeExporter]

It's a PHP bug 44942:
https://bugs.php.net/bug.php?id=44942

When executing wmic.exe to fetch software/hardware information, it will hang:

  ob_start();
  $ret = system("C:\Windows\System32\wbem\wmic.exe path win32_computersystemproduct get uuid");
  $output = ob_get_contents();
  ob_end_clean();

Tried using WScript.Shell COM object and its method Exec() instead, but it 
failed as well.

We may introduce ExecuteCommand function to javascript API.

Another option is to create a helper executable for eg. exec-cmd.exe that would 
work around the PHP bug, it would be called like this:

  system("exec-cmd.exe \"C:\Windows\System32\wbem\wmic.exe path win32_computersystemproduct get uuid\"");

No XP support anymore, right?

The last version that supported XP is the 47.5 release. Some people will still need/ask for XP support, so that 47.5 release will be still provided on Download wiki page for a long time. I am not closing this issue because it is still an issue for those who need to support XP.

Alternatively you could use a NirCmd command-line utility, see:
