When you turn on Automatic Updates, you don't have to search for updates online or worry that critical fixes might be missing.
Windows automatically downloads and installs them for you, using a schedule that you determine.
Reliability Updates are downloaded behind the scenes whenever you're connected to the Internet.
If you are uncertain which edition to install, ask your ACL account administrator before continuing with the installation.
If you prefer to download and install updates yourself, you can also set up Automatic Updates to notify you whenever any high-priority updates become available. If you have not turned on Windows Automatic Updates, your computer is more vulnerable to viruses and other security threats.
When you turn on Automatic Updates, Windows routinely checks the Windows Update Web site for high-priority updates that can help protect your computer against attacks.
