Background information
TweakUI sets can the value for The REG_BINARY NoRecentDocsHistory in the key to "1". This value will suppress the list of recent documents, however, it does not suppress the presence of the Open Recent item in the menu.
In some cases a user might not have TweakUI installed on their system and did not create this REG_BINARY in the key; however, something may have triggered this problem. There are similar applications, like WinChanger, with similar settings, that can cause the same issue.
The setting for the Open Recent menu is a per-user setting, which is why it is located in HKEY_CURRENT_USER. Therefore, if a user logs into the administrative account they may not encounter the problem.
The information about Open Recent settings are stored in the Saved Data file. In some cases deleting the InDesign SavedDated file solves the issue.
