The MS-DOS version 5.0 or later upgrades and packaged products are licensed to customers for use on one computer at a time. If you want to use MS-DOS on another computer (such as a laptop computer), you must remove or uninstall MS-DOS before it is used on the other computer. Microsoft Windows version 3.1 and later is licensed the same as MS-DOS. This also applies to network users.

Microsoft does offer license packs (a license to use the software on one computer) and other options for multiuser environments. Contact End User Sales (800-426-9400) for more information. A brochure titled "Microsoft Licensing Policies: Answers to Frequently Asked Questions" is also available from End User Sales.


Microsoft programs are licensed differently from Microsoft operating systems. A Microsoft Word for Windows licensee who uses a particular computer 80 percent of the time can load the program onto a computer she or he uses 20 percent of the time, without purchasing another license. This applies to Microsoft products such as Microsoft Excel, Word, and Microsoft PowerPoint.

For more information about Microsoft licensing policies, call End User Sales at (800) 426-9400.
