This article demonstrates the installation and configuration steps of WSUS on Windows Server 2016. The thing you need to consider is enough disk space to store updates before starting the installation process.
To begin the process, open up Server Manager and add the new server. Right-click All Servers and select “Add Servers.” Enter the name of the new server.
Select the Server and Click OK. In Server Manager, click “Manage” then “Add Roles and Features.” If you see a “Before You Begin” page, click Next.
Select a Role-based installation.
Select your server in the list
Select the Windows Server Update Services role, Click Next
You’ll be prompted to install other required features, such as different IIS features. Go ahead and install those as well.
The next page will show you Windows features to be installed. Do not uncheck anything here, as some of the items were enabled to support the WSUS installation. Click Next.
Here you’ll see a summary of related WSUS services. I’m going to use the Windows Internal database for WSUS, so I’ll leave this as-is and click Next.
Specify the location for the downloaded updates. Make sure you have enough disk space. Click Next
I’ll accept the defaults. Click Next
Confirm your selection and click Install
Installation process started.
Don't forget to export configuration settings for later use.
Once installation complete, reboot your server.
Once reboot complete, Open up Server Manager, WSUS, Click More
Click "Launch Post-Installation tasks"
Depends on your environment whether you want to configure SSL or not. Click Connect
Start configuring your WSUS post installation tasks as they are self explanatory.
