If you open a workbook that has been worked on by someone else, you may be surprised when you see not one, but two windows open. If these windows are named (in the title bar) something like MyFile.xls:1 and MyFile.xls:2, then the two windows represent different views of the same worksheet.
To solve this problem, make a change or two somewhere in the worksheet. (Make the change in either window; it doesn't matter.) This change can be as simple as editing a cell or entering something into a blank cell and then deleting it.
Next, close one of the windows by clicking the Close button in the upper-right corner of the window. The window should close, but the other window remains open. Notice, as well, that the :1 or :2 notation should disappear from the remaining window's title bar.
Now save the file and close it. When you later reopen it, the extra window is gone. It was there before because Excel remembers how many windows you have open for any given file. It saves that information with the workbook file itself, and then opens that many windows when the workbook is later opened.
If this doesn't solve the problem, it could be that the workbook being opened has an AutoOpen macro that is running and that the macro is opening the additional window. Changing macro-based behavior like this entails changing the macro or disabling it in some way.

Definitely close MyFile.xls:2 before you close MyFile.xls:1
I highly recommend closing all workbooks numbered ":2" and higher first.
Why? Because the ":1" version is the view that most likely has all of the original display settings like show/hide gridlines, frozen rows or columns, and others.
The higher-numbered views typically don't share those same settings. That's a bug, not a feature, and it's annoying.
If you close your original workbook ":1" view before the newer views (":2", ":3", ...), you can lose all those settings and have to redo them.
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
