A family of Microsoft word processing software products for creating web, email, and print documents.
Watermarks are objects (shapes, images or text boxes) which are anchored to the header paragraph in your document. If you display headers/footers, for example by double-clicking the header area, you can then select and delete any watermark that you want to get rid of.
The screen shot below illustrates an "active" header and a selected watermark. You can get rid of a selected watermark by pressing the Delete key on your keyboard.
