Today, the Microsoft Security Response Center (MSRC) posted details about the August security updates.
If you have automatic updating turned on, most of these updates will download and install on their own. Sometimes you may need to provide input for Windows Update during an installation. In this case, you’ll see an alert in the notification area at the far right of the taskbar—be sure to click it.
In Windows 8, Windows will turn on automatic updating during setup unless you choose to turn it off. To check this setting and turn on automatic updating, open the Search charm, enter Turn automatic updating on or off, and tap or click Settings to find it.
If you are a technical professional
The Microsoft Security Bulletin Advance Notification Service offers details about security updates approximately three business days before they are released. We do this to enable customers (especially IT professionals) to plan for effective deployment of security updates.
