List installed program in windows

Question

I would like to get a list of unique installed programs in windows,like in "add/remove programs" in windows. But the data at HKLM\Software\Microsoft\Windows\Current Version\Uninstall, has some duplicates. How do I filter them?

thanks

Answer 1

The recommended Win32 way of doing this would be to use the Microsoft Installer API. The function you want is MsiEnumProductsEx.
