c++ - How can I enumerate/list all installed applications in Windows XP?

Question

When I say "installed application", I basically mean any application visible in [Control Panel]->[Add/Remove Programs].

I would prefer to do it in Python, but C or C++ is also fine.

Answer 1

If you mean the list of installed applications that is shown in AddRemove Programs in the control panel, you can find it in the registry key:

HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionUninstall

more info about how the registry tree is structured can be found here.

You need to use the winreg API in python to read the values from the registry.
