In the event the Table of Contents is not visible, use the following method to restore it.
- Close ArcMap.
- Open Windows Explorer and navigate to the following directory. The AppData folder is hidden in Windows by default. To view hidden folders, refer to Windows: Show hidden files.
- Under the templates directory right-click Normal.mxt and rename it to Normal1.mxt.
- Close Windows Explorer.
- Restart ArcMap. After restarting ArcMap, a new template called Normal.mxt is created.
If the original Normal.mxt (the one renamed to Normal1.mxt) is not customized, the template can be deleted.
If the template is customized, rename it to an appropriate name for easy reference but do not delete it.
