Windows Update scans the user’s computer and provides a tailored selection of updates that apply only to the software and hardware on that specific computer.Windows Update then enables users to choose updates for their computer's operating system and hardware.Gone are the days of losing hours of work to a poorly-timed Windows Update! Open the Settings menu and click Update & recovery. If the update requires a restart, you'll see a new section in the Windows Update window that says "A restart has been scheduled." Under this section, you can choose to have the computer automatically restart ("during a time you don't usually use your device"), or you can click Select a restart time to choose the time and day you want the restart to occur.If you want to simply restart the computer now, click Restart now.When Automatic Updates is configured so that updates automatically download and install, users do not need to visit special Web pages or remember to periodically check for new updates.

If you are prompted to download the file, this means that the client can reach the WSUS server and it is not a connectivity issue. If you are not prompted to download the file, you might have a name resolution or connectivity issue, or WSUS is not config¬ured correctly.

If you are using Group Policy settings to configure Windows Update, use the Resultant Set of Policy (RSOP) tool (Rsop.msc) to check the computer’s effective configuration.
