Lock Down Display Settings

If you administer several office PCs, you may want to prevent users from changing their screen resolutions or digging into the details of your monitor and video card settings. This Registry tweak hides the Settings tab in the
Display Properties window to make all resolution and monitor settings
inaccessible.

1. Start > Run > Regedit

2. Go to
HKEY_CURRENT_USER\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\POLICIES.

3. Right-click the key and choose New and Key to create a new key, and
name it System. With the new System key highlighted, right-click and
choose New and DWORD Value. Name the valueNoDispSettingsPage.

4. Double-click this new value and set the Value data to 1 to remove
the Settings tab from the Display Properties window. The effect will be
immediate.

You can restore the Settings tab either by deleting this
NoDispSettingsPage value or setting the value data to 0.
