When you clear the Add new documents to Documents on Start Menu box in TweakUI, Windows 2000 Logo compliant programs no longer display the most recently used (MRU) file list, including the MRUs in the File, Save, and Open dialogs?
Windows 2000 Logo compliant programs must honor the Do not keep history of recently opened documents Group Policy at User Configuration\AdministrativeTemplates\Start Menu & Taskbar.
To resolve the problem, either check the Add new documents to Documents on Start Menu box in TweakUI, or use Regedt32 to set the NoRecentDocsHistory value name, a REG_BINARY data type, at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer, to 00 00 00 00.
NOTE: TweakUI enables the policy by setting NoRecentDocsHistory to 01 00 00 00.
