3. On the General tab, click to clear the Recently used file list check box, and then click OK.

To delete the most recently used files list in the 2007 Microsoft Office suites, follow these steps:

To modify the registry key and to clear the most recently used files list in a program in Office, follow these steps.

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate the following registry key, as appropriate for your version of Office:
2007 Office suite
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Open Find
Office 2003
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Open Find
Office XP
HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Common\Open Find
3. In the Open Find subkey, locate the program for which you want to clear the most recently used files list.

In each program subkey, you find another subkey that is named Settings. In that subkey, you find several additional subkeys. Each of these subkeys contains a most recently used files list.

For example, the Microsoft Office Word\Settings subkey contains subkeys such as Insert File, Save As, Open, or Modify Location. These keys may vary depending on the past actions that were performed in Microsoft Word.

Under each subkey is another subkey that is named File Name MRU.
4. To delete a specific list of most recently used files, delete the Value entry in any File Name MRU subkey.
