What is it?

Windows Update is a service provided by Microsoft that provides updates for the Microsoft Windows operating system and its installed components, including Internet Explorer. Windows Update can be configured to install critical updates automatically so long as the computer is connected to the Internet, without the user needing to install them manually, or even be aware that an update is required.
Description of wuauclt.exe from Microsoft
When you turn on automatic updating, most updates will download and install without you having to lift a finger. But sometimes Windows Update will need your input 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. If you don't respond to a Windows Update alert, your PC might end up missing an important download.
