Vista - win32_product not valid

I am in the process of writing a query for win32_product but the component is
not installed on some of our boxes. I don't have the luxury of adding this
component, is there a another way to gather installed apps on a server via
powershell?

Thanks in advance,

By component I assume you mean the Win32_Product?

You can query the HKLM\Software Regkey. Unfornutately, its a little over
zealous (Win32_Product only display stuff installed using Windows
Installer... this is everything) on the results, but it may be good enough
for your purposes.

CODE:
================
function Get-InstalledApplications{
Param($server)
$hklm =
[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine,$server)
$InstalledApps = $hklm.OpenSubKey("Software")
$InstalledApps.GetSubKeyNames()
}
================

I find that a good substitute is looking at the Uninstall key. It doesn't
show you everything though.

I typically use this approach also because gwmi Win32_Product is
phenomenally slow on most machines that I have tried it on.
