Excel Process Stops Responding (Hangs) on Shut Down

Excel may be slow to shut down if the Excel15.xlb file is corrupted. This file stores changes to the ribbons in Excel.

A simple fix to this issue is to rename Excel15.xlb. A clean Excel15.xlb file is rebuilt the next time you start Excel.

The Excel15.xlb file is located in the C:\Users\user\AppData\Roaming\Microsoft\Excel folder.

To rename the Excel15.xlb file, see Renaming or Deleting the Excel xx.xlb File.
