5 Ways To Check Installed Version Of IIS In Windows

IIS is available in most modern Windows operating systems but needs to be enabled manually. However, every Windows OS version has a different IIS version available, with different features. Learn how to check which IIS version is installed on your computer.

IIS Version

Internet Information Service (IIS) is a web server from Microsoft used to host anything on the web. It will host your websites and applications on the web. It provides support for HTTP, HTTPS (which contains a security certificate and is more secure than HTTP), FTP (File Transfer Protocol used to transfer files), and SMTP (Simple Mail Transfer Protocol used in transferring email). It is included in Windows by default in optional features.

You can enable IIS from Optional Features. Press the Windows button and then type “Turn Windows features on and off”. Select “Internet Information Services.” You will be asked to restart the system to finish installing the request.

To check your installed IIS version, type in “reg query HKLM\SOFTWARE\Microsoft\InetStp” in an elevated Command Prompt, and view the value for VersionString in the results.
