Need to get the installed softwares list and there versions in Windows?

Hi,
Please help me with this;
I need to get the list of softwares installed along with their versions in Windows irrespective of OS.
In details, need to fetch the DsiplayName along with the DisplayVersion of all the softwares installed from the uninstall section of registry hive ;
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall -if present(64bit machines have these).

Can anyone create like a batch file, run it and get the data from a text file generated in a proper manner(i.e. Diisplayname and corresponding DisplayVersion)??

Thanks,
Subrat
