Not yet. Downloading updates only saves the update files to your computer. You must then install the updates to help protect your computer.
If you use Microsoft Update, the updates you select are downloaded and installed at the same time. If you have configured automatic updating to download updates but not install them, you will get a notice like the following when the updates have downloaded.
This notice appears after the download is finished. If you see this notice, don’t delay. Click the balloon to install the updates right away.
If you are an IT professional or a system administrator, or if you’d like additional information about security updates, go to Security TechNet or read the Microsoft Security Response Center Blog.
