To completely uninstall Office 2013 from your system automatically, open the "How to uninstall Office 2013 or Office 365" page (link in Resources) and click the "Microsoft Fix It" button. You can back up any registry key by right-clicking it, selecting "Export," typing a name for the backup and then clicking "Save." Saved keys can be restored by double-clicking them. Ensure the key or subkey contains the rest of the characters - 0FF1CE}- or F01FEC, for example - before you delete it. The asterisk character in various registry keys and subkeys represents one or more random characters. Don't forget to delete the registry entries common to both click-to-run and MSI installations.

Also delete the "_Office15*" subkey from the "UpgradeCodes" key. Expand the "HKEY_CLASSES_ROOT\Installer" key and then delete the "_F01FEC" subkeys from the "Features," "Products" and "UpgradeCodes" keys.

Expand the "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office" key and then delete the "15.0" subkey.
