Microsoft security updates FAQ
Here are answers to some frequently asked questions about Microsoft security updates.
| Q. | I updated my software last month. Do I have to do it again? |
| A. | Yes. Each Microsoft security update addresses a specific issue. Unless you install the update, you will not be protected from that particular issue. |
| Q. | I downloaded the updates. Am I done? |
| A. | Not yet. Downloading only saves the update files to your computer, installing enables them to go to work to help protect your computer. If you use Microsoft Update or Office Update, the updates you select are downloaded and installed at the same time. If you have configured your Windows Automatic Updates feature to download updates but not install them, you will get a notice like the following when the updates have downloaded:

| Q. | Can my computer update itself? |
| A. | Yes. The latest versions of Windows include an Automatic Updates feature, which allows you to schedule downloads and install them on a schedule that you specify. |
| Q. | How can I learn whether new updates have been released? |
| A. | Whenever major security updates are released, Microsoft sends instant message or e-mail alerts to subscribers of our free notification service. Learn more about getting IM or e-mail notification about security alerts. |
| Q. | What do the severity ratings mean? |
| A. | The Microsoft Security Response Center (MSRC) has developed a rating system to help customers determine which updates to install first. The severity rating system provides a rating from "low" to "critical" for each computer vulnerability. |
