Microsoft Word Viewer was a free application developed by Microsoft that allowed users to open and view documents created in Microsoft Word without needing the full version of the software. It supported various Word file formats, making it easy for users to access and read documents on their computers. Although it was useful for viewing documents, Microsoft Word Viewer did not allow users to edit or create new documents. The application was discontinued in 2017, and users were encouraged to use Microsoft Word Online or other alternatives for viewing Word documents.
