Broadly speaking, bundled software is software that comes with a new Windows® or Macintosh® computer. While some bundled software, such as the operating system, is absolutely essential and every machine will have one, pretty much everything else can change. Not only the exact software applications, but also the licensing terms of use and other details may vary. Bundled software is also used less frequently to apply to several software applications that are marketed in a single package.

Because a computer manufacturer can purchase software in bulk, it may be relatively inexpensive to place software on all new computers. In addition, it may be a selling point for some customers. In addition, trial software for other companies may generate goodwill. Bundled software is different than pre-installed software that a user has ordered and paid for along with a new machine and which has received a courtesy factory install.

Macintosh® bundled software has an Address Book, calendar called iCal®, instant messaging program called iChat®, music program called iTunes®, Mail, and a web browser called Safari®. It generally also includes the iLife® software suite. This package has four programs: iPhoto® for organizing photographs; iMovie® for creating or editing movies; GarageBand® for recording or mixing songs; and iWeb™ for creating custom websites. With Snow Leopard®, also known as Mac OS X 10.6, an alternate version of QuickTime® may also be available. Trial software and non-Apple products are not the norm.

Windows® computers, too come with an installed operating system. The software bundle may include full versions of software applications, as well as lite or demo versions, and trial versions that have a limit of 60 or 90 days. In the case of lite software, the user has the option to upgrade. With demo or trial software, the user can either purchase a license to unlock the software that is already on the machine or purchase a full version. If the user does not wish to use the software, it is possible to uninstall it, which should be done according to manufacturer’s instructions to avoid leaving unwanted remnants behind. Sample bundled software that might be included with a Windows® computer includes: a demo or trial version of an antivirus program, Windows® Media Player, Windows® Photo Gallery, Windows® Movie Maker, Windows® DVD Maker, a collection of games, the browser Microsoft® Internet Explorer®, Adobe® Reader®, Microsoft® Works, and a trial version of Microsoft® Office.
