Ill 7-7 7 Automate Operating System Patching with Automatic Updates In addition to the on-demand Windows Update site, Microsoft provides the Automatic Update service to help you keep your system up-to-date. This service uses your Internet connection to check for new security updates.

If you need to change the setting, choose a time that your system will be powered on but not in use. Automatic Updates Settings The options for installation of updates give you the opportunity to customize it to suit your needs. We will describe each one and give an example of where it might be used. Automatic (Recommended) This setting is recommended by Microsoft because it ensures updates will be downloaded and installed without user intervention. This is 7 especially important for those who are not aware their systems need protection. In the past, systems were compromised simply because their owners did not know security was an issue. Now these systems are protected by default, and often without the user’s knowledge. This setting is also a good basic setting for most configurations. When an update is available, you will receive notification via a small pop-up message from the Automatic Updates service. You may choose to install the update immediately or wait for the automatic installation process to pe ...
