One way to delete a watermark from your Microsoft Word document is to use the Watermark menu. This is the menu that you also use to add watermark to your documents, according to HowtoGeek.

Open Your Document: Launch Microsoft Word and open the document from which you want to remove the watermark. Access the Design Tab: Click on the ‘Design’ tab located in the top menu of Word.

Word will then place the faint watermark behind the text (or where the text will go if you don't yet have any in your document). In my case, I've gone for the Confidential watermark.

Adding a watermark to a Word document is important if you want to protect confidential data and to indicate the legality of a document. You can also add watermarks in a bid to avoid counterfeiting.

The Document Inspector feature will search and remove hidden data in your document, such as comments, watermarks, and other metadata before, publishing.
