Microsoft Works
Microsoft Works is a word processor developed by Microsoft that is often included on OEM computers. Microsoft Works is used as an alternate solution to Microsoft Word because of the cost difference between the two different programs.
Because Microsoft Works is completely different from Microsoft Word, these programs use different files (Microsoft Word documents are usually *.DOC and Microsoft Works documents are usually *.WPS). Therefore, users who wish to open a Microsoft Works document in Microsoft Word must convert the files to open them properly.
