Installing Windows 7
Check For Updates
When you click Check For Updates, Windows Update will retrieve a list of available
updates from the Internet. You can then click View Available Updates to see what updates
are available. Updates are marked as Important, Recommended, or Optional. Figure 1.3
shows a sample list of updates.
FIGURE 1.3 Checking for updates
There are two ways that a user can receive updates: directly from Microsoft or using a
Microsoft Windows Server Update Service (WSUS). WSUS runs on a Windows server and
that server goes out to Microsoft’s website and downloads the updates for your Windows
clients. This allows client machines to receive their updates from a local server.
One advantage to using WSUS is that administrators can approve the updates before
they get deployed to the client machines. Another advantage is that your clients only need
to download updates locally without using your Internet bandwidth.
WSUS is discussed in detail in MCTS: Windows Server 2008 R2 Complete
Study Guide by William Panek (Sybex, 2011).
