How to Suppress and Control Verb Visibility
This topic tells you how to control verb visibility.
You can use Windows policy settings to control verb visibility. Verbs can be suppressed through policy settings by adding a SuppressionPolicy subkey or a SuppressionPolicyEx GUID value to the verb's registry subkey. Set the value of the SuppressionPolicy subkey to the policy ID. If the policy is turned on, the verb and its associated shortcut menu entry are suppressed. For possible policy ID values, see the RESTRICTIONS enumeration.
