If you’re planning to host websites, test web applications, or develop projects locally on a Windows computer, enabling Internet Information Services (IIS) is one of the first steps you need to take. IIS is Microsoft’s built-in web server that allows you to run websites directly from your Windows PC without installing third-party web server software. Whether you’re a beginner or an experienced web developer, IIS provides a reliable environment for testing and managing web applications.
This guide walks you through the exact process of turning on IIS in Windows, following the same steps demonstrated in the video tutorial.
What Is IIS?
Internet Information Services (IIS) is a web server created by Microsoft for Windows operating systems. It enables users to host websites, web services, FTP servers, and web applications locally or on production servers. IIS supports technologies such as HTML, CSS, JavaScript, PHP, ASP.NET, ASP.NET Core, CGI, and many other web development frameworks.
Because IIS is integrated into Windows, it offers excellent performance, security, and compatibility with Microsoft development tools.
Why Enable IIS?
There are several reasons why developers and IT professionals use IIS:
- Test websites before uploading them to a live hosting server.
- Develop ASP.NET and PHP applications locally.
- Create a local web server for development.
- Learn Windows web server administration.
- Host internal company websites or applications.
- Configure virtual directories and multiple websites.
Enabling IIS transforms your Windows computer into a fully functional web server.
Step 1: Open Windows Features
The first step is to access the Windows Features panel.
Open the Control Panel, navigate to Programs, and then click Turn Windows features on or off. Windows will load a list of optional features that can be enabled or disabled on your computer.
Scroll through the list until you find Internet Information Services.
Step 2: Expand Internet Information Services
Instead of simply checking the IIS box, expand the Internet Information Services section by clicking the plus (+) icon.
The video carefully expands each category to ensure all necessary components are available. This is especially important for developers who require advanced IIS features instead of only the default installation.
Step 3: Enable Web Management Tools
Inside IIS, expand Web Management Tools.
Make sure the IIS Management Console is selected. This component installs the graphical interface used to manage websites, application pools, virtual directories, and server settings.
Without the Management Console, administering IIS becomes much more difficult.
Step 4: Configure World Wide Web Services
Next, expand World Wide Web Services.
This section contains the main features responsible for serving websites and web applications. The video demonstrates enabling multiple subcategories to ensure IIS has complete functionality.
These categories include:
- Application Development Features
- Common HTTP Features
- Health and Diagnostics
- Performance Features
- Security
Each section contains optional components that provide additional capabilities depending on your development needs.
Step 5: Enable Application Development Features
One of the most important sections shown in the tutorial is Application Development Features.
Here, several options are selected, including support for:
- .NET Extensibility
- ASP.NET
- CGI
- ISAPI Extensions
- ISAPI Filters
- Server-Side Includes
These features allow IIS to process dynamic web applications instead of serving only static HTML pages.
If you develop PHP websites, enabling CGI is particularly important because it allows PHP to communicate with IIS using FastCGI.
Step 6: Select Common HTTP Features
The tutorial also enables several options under Common HTTP Features.
These features include support for:
- Default Document
- Directory Browsing
- HTTP Errors
- Static Content
These settings allow IIS to correctly serve website files, display custom error pages, and automatically load default pages such as index.html, default.aspx, or index.php.
Step 7: Configure Additional IIS Features
Depending on your Windows version, you may also see optional features for diagnostics, logging, request filtering, compression, and security.
The video reviews these categories and enables the components necessary for a complete IIS installation. Although some options are optional for beginners, installing them now can save time later if your projects require additional functionality.
Step 8: Install IIS
After selecting all required IIS components, click OK.
Windows will begin installing the selected features automatically. During this process, Windows copies the required files and configures IIS in the background.
Installation usually takes only a few minutes, depending on your computer’s performance.
Once the installation is complete, Windows displays a confirmation message indicating that the requested changes have been successfully applied.
Step 9: Verify the Installation
After installation finishes, open your preferred web browser.
In the address bar, type:
If everything has been configured correctly, the IIS default welcome page will appear.
This confirms that IIS has been installed successfully and your local web server is running properly.
Managing IIS
Once IIS is enabled, you can launch IIS Manager by pressing Windows + R, typing inetmgr, and pressing Enter.
From IIS Manager, you can:
- Create new websites
- Manage application pools
- Configure bindings
- Add virtual directories
- Manage SSL certificates
- Configure authentication
- Monitor server performance
This graphical interface makes IIS administration simple, even for beginners.
Conclusion
Enabling Internet Information Services in Windows is a straightforward process that provides a powerful web server for local development and testing. As demonstrated in the video, expanding the IIS options and selecting the appropriate features ensures that your installation supports modern web technologies, including ASP.NET, PHP, CGI, ISAPI, and static website hosting.
Once IIS is installed, you can begin building websites, testing applications, and learning server administration without installing additional web server software. Whether you’re developing personal projects, business applications, or enterprise websites, IIS offers a stable, secure, and professional platform for Windows-based web development.
