Downloading available updates
If you set up automatic updating to notify you before downloading any updates, an icon appears in the notification area each time new updates are found.
To download available updates
Your selected updates will be downloaded in the background, allowing you to continue working uninterrupted. This way, downloading will not interfere with or slow down other network activity, such as Internet browsing.
When downloading is finished, the icon appears in the notification area again, this time to notify you that updates are ready to be installed.
To pause or resume downloading
After the download has started, you can pause or resume downloading at any time. If you close your Internet connection or restart your computer after pausing a download, Windows automatically resumes the download the next time you are connected to the Internet.
