This behavior is controlled by how Excel windows are saved and reopened, not by a setting to “lock” a fixed position. Excel reuses the last window layout that was saved with a workbook or with Excel itself.
To keep a consistent layout:
- Open one of the workbooks.
- Arrange and resize the Excel window exactly where it should appear on the desktop.
- Close any extra Excel windows for that same workbook (if there are multiple windows like
Book1:1,Book1:2). - Press
Ctrl+Sto save the workbook while it is in the desired position. - Close Excel.
- Reopen the workbook; Excel should now reuse the last saved window arrangement for that file.
If multiple windows of the same workbook are being saved, Excel can reopen them in different positions. In that case, close the extra windows first and then save, as described above.
