The Software Manager is a program that is installed on Original Equipment Manufacturer PCs. This helps keep preinstalled programs up-to-date.

The update notices include the size of the update, and a description of the update. From this list, choose the updates you wish to install. Clicking on an update listing allows you to learn more about the update, or to remove the update notice.
Also Internet Explorer 10 is outdated on Windows 7, and I would advise that you upgrade to Internet Explorer 11 via this link:
