You may experience a long delay where an Office 2013 application seems to hang for a number of seconds when you click on the File menu item, for example when trying to access the Save options for a Word or Excel file:
Clicking on File should bring up the Backstage view, where you can manage your files and related data by creating or saving files or setting options:
In cases where it takes a long time for the Backstage to appear, the application may be trying to contact a network location such as OneDrive, and network latency could cause the application to hang for a number of seconds. If you are consistently experiencing this symptom, and you are not using OneDrive, you can resolve the issue be enabling the following option: File > Options > Save > Don't show the Backstage when opening or saving files
With this setting enabled, the File menu should show up immediately. Instead of getting a Backstage view when clicking Save or Open, you will be presented with a classic Open or Save dialog box instead:
In order to implement this setting on all computers in your organization, you can use a registry key to enable this option. Configure the registry key below with a value of 1. Create the SkipOpenAndSaveAsPlace key as a DWORD value if it does not already exist.
