Installing WSUS

With the prerequisites out of the way, you can now install WSUS. Here I will lead you through these steps.

1. Locate the WSUS application you've downloaded, and double-click it to begin the installation.
2. When the wizard's Welcome page appears, click Next.
3. Make sure that Full Server Installation Including Administration Console is selected, and click Next.
4. Review the License Agreement. Select I Accept the Terms of the License Agreement, and click Next.
5. Accept the defaults on the Select Update Source page. This will set the C:\WSUS folder to be used to store the updates. Alternatively, you can browse to a different location to store the updates. Click Next.
6. Review the options on the Database Options page. Accept the default Install Windows Internal Database On This Computer in the C:\WSUS folder. Click Next.
7. On the Web Site Selection page, accept the default Use the Existing IIS Default Web Site (Recommended) option.
   This graphic has some important information under the selections. It identifies how you should configure the client computers to access Windows Server Update Services using http://servername. I have installed it on a server named DC1, so the address is http://DC1. Port 80 is the default port used for HTTP.
8. Review the information on the Ready to Install page. Notice that it also identifies the path for the Client Self Update Site as http://serverName/selfupdate. Click Next to begin the installation.
9. After several minutes, the installation will complete. Click Finish.
10. The Windows Server Update Services Configuration Wizard will launch automatically.
11. Review the information on the Before You Begin page and click Next.
12. Review the information on the Microsoft Update Improvement Program page and click Next.
13. On the Choose Upstream Server page, accept the default Synchronize From Microsoft Update and click Next.
    If you were using both upstream and downstream servers, you'd configure the downstream servers to obtain their updates from the upstream server, and the upstream servers would obtain their updates from the Microsoft Update site.
14. If your network uses a proxy server, specify the details in the Specify Proxy Server page. Click Next.
15. The Connect to Upstream Server page will appear. Since this is the only WSUS server, the Windows Update server is considered the upstream server. Make sure that your server has Internet connectivity, and click Start Connecting. This process will take several minutes to complete. When it completes (the progress bar will reach the far right-hand side), click Next.
16. On the Choose Languages page, select your language and click Next.
17. Review the information on the Choose Products page. By default, Office updates and Windows updates are included. You can select or deselect any updates desired. Click Next.
18. Review the information on the Choose Classifications page. The graphic shows the default selections, but you can choose other classifications to download. Click Next.
19. On the Set Synch Schedule page, accept the default Synchronize Manually. Click Next.
20. Review the information on the Finished page. The Launch The Windows Server Update Services Administration Console and Begin Initial Synchronization Server selections are both checked by default. Click Next.
21. Review the information on the What's Next page and click Finish. Note that when WSUS connects with the Microsoft Update site at this point, it does not download the updates but instead downloads an XML file that describes the updates. Once the updates are approved, they are downloaded to the WSUS server and are available to deploy to clients.
22. WSUS will launch. Expand by the server by clicking the plus (+) sign. Select Updates in the Update Services console, and you'll see a display similar to the following graphic.
23. At this point, WSUS is successfully installed, and other network components can be configured to ensure your clients get their updates from this WSUS server.
