NoteHKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\TemporarySettingChanges
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
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 more restrictive than DisableAll in the PermanentSettingChanges 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 change display settings. |
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.
