Windows Update is the online extension of Windows. It's a web site where you find the most recent updates for your operating system, software programs and hardware. Windows Update scans your computer and lists the code updates required for your system. Then you can choose whether to download and install them.
To use Windows Update, you need to establish a connection to the Internet.
The first time you go to the Windows Update web site, click Yes when prompted to install any required software or controls.
You might need to be logged on as an administrator or a member of the Administrators group in order to perform some tasks.
