How to Close a Word 2010 Document
Closing a Word 2010 document when you're finished working with it is simple. When you're done writing a Word document, you just need to do the electronic equivalent of putting it away. That electronic equivalent is the Close command:
Choose the Close command from the File tab menu.
Alternatively, you can use the handy Ctrl+W keyboard shortcut. If you haven't saved your document recently, Word prompts you to save before you close. When the document has been saved, closing it simply removes it from view — you're done!
If your document needs to be saved, click the Yes button in the prompt that appears.
If you haven't ever saved the document yet — shame on you! — you see the Save As dialog box.
If the Save As dialog box appears, type a name for your document in the File Name text box.
Word automatically selects the first line or first several words of your document as a filename and puts it in the Save dialog box. If that’s okay, you can move to Step 4. Otherwise, type a name in the File Name box.
(Optional) Choose a location for your file.
Use the various gizmos in the Save As dialog box to choose a specific folder for your document.
Click the Save button.
The file is now safely stored in the PC’s storage system.
You don't have to choose the Close command. You can choose the Exit command from the File tab menu if you're done with Word, which is almost the same thing: You're prompted to save your document if it needs saving; otherwise, the Exit Word command quits Word rather than keeps the window open.
You can also just close the Word program window, which closes the document. When you close the last open Word program window, you also quit Word.
