We use a software to connect up remotely to computers called Teamviewer. We always inventory these when we are deploying new computers but I would like to be able to pull these up by looking at the same open-audit software. The keys can be found in the registry using the following path.
Windows XP - HKLM\Software\TeamViewer\Version5\ClientID
Windows Vista/7/8 - HKLM\Software\Wow6432Node\TeamViewer\Version5\ClientID
The Version5 being an old version. They have version8 out right now and still retains the same path. I would say 5-8 would be nice to be able to pull. If you need any assistance from me to try and get this working let me know and I would be more than happy to test things out for you. If noone else has any interest in this it wouldn't be a big deal just would be nice.
