Final answer:
Opening Microsoft Word presents a blank document titled 'Document1' or a number derivative if others are open. The name changes when the document is first saved.
Step-by-step explanation:
When you open the Word application, it typically starts up with a blank document. This is a clean slate for you to begin typing and formatting your new document. The temporary name of this document is usually 'Document1', or a similar sequentially-numbered name if you open additional new documents during the same session. This name remains until you save your document for the first time, at which point you'll be prompted to give the document a unique name of your own choosing.
