Introduction
The new modular architecture in IIS 7.0 is great. You can use it to limit the potential attack surface on your IIS installation, or to replace built-in features with third-party or custom implementations. In general, this new architecture offers you an unprecedented ability to control how you deploy IIS on your network.
But if there is a downside to this new architecture, it is that you can no longer be certain every IIS component you need is available, just because IIS has been installed. You might also discover that making sure multiple servers all have the same IIS components can be a chore.
To work around these issues, we are publishing 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. Use the table below to match IIS component names with their registry keys.
Registry Keys
These keys appear in the following registry hive:
HKEY_LOCAL_MACHINE\Software\Microsoft\InetStp\Components\
