How to Reset the Excel 2003 Application to Default Settings

1. Save and rename your workbook and worksheet settings templates if you want to use them again. Save them in the Templates folder, which is located here: C:\Documents and Settings\user_name\Application Data\Microsoft\Templates.
2. Click on your computer's start menu and search for the following in the search dialog box at the bottom of the menu: C:\Program Files\Microsoft Office\OFFICE11\XLSTART. Delete any template files in this folder. If you'd only like to delete workbook settings templates, delete templates with 'Book.xlt.' If you'd only like to delete worksheet settings templates, delete templates with 'Sheet.xlt.'
3. Open Microsoft Excel 2003 on your computer if there are no files located in the folder specified in Step 2. Click on 'Tools,' then 'Options' and then on the 'General' tab. Delete the Book.xlt and/or Sheet.xlt files specified beside 'At startup, open all files in.'
