Do not keep history of recently opened documents
User Configuration\AdministrativeTemplates\Start Menu & Taskbar
Prevents Windows 2000 and programs Certified for Microsoft Windows from creating and displaying shortcuts to recently opened documents.
If you enable this policy, the system and Certified for Microsoft Windows programs do not create shortcuts to documents opened while the policy is in effect. Also, they retain, but do not display, existing document shortcuts. The system empties the Documents menu on the Start menu, and programs Certified for Microsoft Windows do not display shortcuts at the bottom of the File menu.
Disabling this policy has no effect on the system.
You can use this policy, in coordination with the Remove Documents menu from Start Menu and Clear history of recently opened documents on exit policies in this folder, to manage access to recently opened files.
The system saves document shortcuts in the user profile in the System-drive \Documents and Settings\ User-name \Recent folder.
If you enable this policy and do not enable the Remove Documents menu from Start Menu policy, the Documents menu appears on the Start menu, but it is empty.
If you enable the policy, and then later disable it or set it to Not configured , the document shortcuts saved before the policy was enabled reappear in the Documents menu and program File menus.
This policy does not hide document shortcuts displayed in the Open dialog box. See the Hide the dropdown list of recent files policy.
