Office Word. How to open the same document in separate windows?

If you'd like to work on different parts of the same document, you can click "View" - "New Window" or "Split". New Window - well, it's quite obvious. "Split" means the 2 windows will be stacked.

Repeat for as many documents as you like. Note that it is still 1 document - edits you do in 1 window will be transferred to all windows.

On older versions of Word the new window command is under the 'window' menu.

Open the document. Then click File, then Recent, right click on the open document, then Open a Copy. Same document in two separate windows - done.

You can also right click on the documents icon (in Windows 7) and select "new", this will open a new instance of the same file.
