DisableAll

HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\PermanentSettingChanges

Data type Range Default value
REG_DWORD 0 | 1 0

Description

Determines whether users can save changes to the display settings of graphics devices. The display settings, usually changed by using Display in Control Panel, include characteristics such as resolution, color depth, and refresh rate. This entry is less restrictive than DisableAll in the TemporarySettingChanges subkey, which allows users to change display settings, but not save these changes.

Value Meaning
0 All users can save the changes they make to display settings.
1 No users, including the Administrator, can save changes made to display settings.
 

Note Image Note

Windows 2000 does not add this entry to the registry. You can add this entry to override the default configuration of graphics drivers by using a program which edits the registry.

Setting DisableAll to 1 is more restrictive than disabling Display in Control Panel (NoDispCPL). DisableAll prevents the use of the ChangeDisplaySettings API. Disabling Display in Control Panel does not prevent the user from using other programs that call the ChangeDisplaySettings API.
