  • on Windows Server 2012 R2 and Windows 8.1
  • on Windows Server 2012 and Windows 8
  • on Windows Server 2008 R2 and Windows 7

IIS 7 and newer versions are built on a modular architecture, plugging in to the kernel-mode HTTP.SYS listener. User-mode Modules can be added or removed individually so that only modules required for specific functionality have to be installed.

IIS includes these module groups:

  • HTTP (request-processing pipeline, errors, redirects)
  • security
  • content
  • compression
  • caching
  • logging and diagnostics

The IIS Manager (INETMGR) is the IIS administrative GUI.

The command-line utility "AppCmd" provides a scriptable interface to the IIS configuration data.

The PowerShell WebAdministration module is included with IIS 7.5+.

The newer PowerShell IISAdministration module is included in IIS 10+. It is the only IIS PS Admin module supported on Nano server at the time of release.
