Windows Update is a feature of Microsoft Windows that automatically updates the operating system and device drivers. By default, Windows Update is enabled, and it is automatically configured to check for, download and install updates everyday. It is recommended that you do not change the default Windows Update settings. However, you can still configure Windows Update in order to tightly control its behavior. For instance, you could decide to manually run Windows Update and select which updates you want to install. To configure Windows Update, follow these steps:
Open the Start menu, click All Programs, and select Windows Update.
Windows Update will show on the screen. Click Change settings on the left side of Windows Update.
In the next window, you can change settings for Windows Update. In most cases, you can leave the settings as is. However, if you prefer manual settings, configure Windows Update as shown in the picture below.
