WPKG is a software deployment system and no inventory system.

You could run a batch file or DOS command script to parse the output of 
querying the uninstall registry tree.
You would filter out the DisplayName and DisplayVersion values.

Find an example below.

REM --- code start (watch for line wraps)
@echo off
cls
echo.

set script_name=%~dpn0

if exist "%script_name%_%COMPUTERNAME%.txt" move /y 
"%script_name%_%COMPUTERNAME%.txt" "%script_name%_%COMPUTERNAME%_old.txt"
if exist "%script_name%_%COMPUTERNAME%_filtered.txt" move /y 
"%script_name%_%COMPUTERNAME%_filtered.txt" 
"%script_name%_%COMPUTERNAME%_old_filtered.txt"

echo Reading installation information ...
reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" /s 
 >"%script_name%_%COMPUTERNAME%.txt"

reg query 
"HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" 
 >nul 2>&1
if ERRORLEVEL 1 goto :quit

echo.
echo Reading WOW64 installation information ...
reg query 
"HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" 
/s >>"%script_name%_%COMPUTERNAME%.txt"

:quit

echo.
echo Creating filtered output ...
findstr DisplayName "%script_name%_%COMPUTERNAME%.txt" | findstr /v 
"ParentDisplayName Hotfix Update" | sort /o 
"%script_name%_%COMPUTERNAME%_filtered.txt"

echo.
pause
REM --- code end
