The Windows 8 developer preview build installation media contains an executable called wicainventory.exe. Wicainventory tool collects application and device information. There is also a wica.ini file that contains 2 URLs. I assume that the Tool is used by Microsoft to collect telemetry data.
While there are plenty of other methods to collect software and hardware inventory data, wicainventory provides a nice way to collect Internet Explorer add-on information. For running wicainventory standalone the following files must be copied from the Windows 8 installation sources.
.:\sources\wicainventory.exe
.:\sources\wica.dll
.:\sources\aeinv.dll
.:\sources\devinv.dll
To collect Internet Explorer Add-on information, run the following command at the command prompt.
wicainventory.exe /IEADDONS /output IEAddons.xml
With a few clicks the output xml can be easily imported into Microsoft Excel where then you get a clear view of the installed Internet Explorer Add-on’s.
