Hi @Binumon George ,
Microsoft has published a list of registry keys that show whether any given IIS module has been installed. Use these registry keys to programmatically check on IIS components. If a component has been installed, the registry key has a DWORD value of 00000001. If a component has never been installed or has been uninstalled, the registry key does not exist. The registry hive is as follows:

HKEY_LOCAL_MACHINE\Software\Microsoft\InetStp\Components\

Refer to this document, match the IIS component name to its registry key.
