Software List - Inventory -WMIC Product

Question

Hi,

I am trying to generate a list of the installed software using WMIC Product, but it seems like I am getting one a few items listed with command.
See below screenshot for the installed product (available in Control Panel) and the WMIC Product Output as well as my current Windows version.
What might I am doing wrong?

Answer 1

My output is empty / blank, see belwo.

The example is missing the trailing slash after Uninstall. I get different software lists when I look at the 32/64 bit entries.

Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | sort-object -property DisplayName | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize

Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | sort-object -property DisplayName | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize

For a combined view, run this.

function Analyze( $p, $f) {
    Get-ItemProperty $p |foreach {
       if (($_.DisplayName) -or ($_.version)) {
            [PSCustomObject]@{ 
                    From = $f;
                    Name = $_.DisplayName;
                    Version = $_.DisplayVersion;
                    Install = $_.InstallDate 
             }
       } 
    }
}

$s = @() 
$s += Analyze 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' 64
$s += Analyze 'HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*' 32
$s | Sort-Object -Property Name 

Instead of WMIC, try Get-CimInstance

Get-CimInstance Win32_Product | Sort-Object -property Name | Format-Table -Property Version, InstallDate, Name

One behavior I have noticed is that referencing Win32_Product generates an event for each product in the application event log. Check your log. You might be getting an error that is stopping the analysis.

Answer 2

Hi,
I guess it might be related that "Win32_Product WMI class represents products as they are installed by Windows Installer. A product generally correlates to one installation package."

And per further searching, there is also powershell command shared to get installed applications:
Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize
