In Windows, Microsoft Word documents (.doc and .docx) can be opened by double-clicking on the file. The document will open in Microsoft Word if it is installed on your device.
If Microsoft Word is not installed, you can open documents with the free Microsoft Word Viewer application. You can download this application from the Microsoft Download Center (https://www.microsoft.com/en-us/download/details.aspx?id=4). Once the application is installed, you can then double-click on the Word document to open it in the Word Viewer.
Alternatively, you can open the document in a different word processor such as Google Docs, LibreOffice, or Apple Pages. To do this, first upload the document to the cloud (using Google Drive, Dropbox, or any other cloud service) or save it to an external hard drive. Then, open the document in the corresponding program.
Finally, you can open the document using an online viewing service such as SmallPDF or PDF Elementary. These services allow you to view Word documents without having to install any software or applications. You just need to upload the document to their website, and you will be able to view it directly in your internet browser.
No matter what method you use, you should never open a Word document directly from an email attachment or from an unknown source. This can result in the introduction of malicious code into your device.
